+**0.19.0**
+- Fix direwolf connection setup by implementing a retry loop
+- Pass direct sampling mode changes for rtl_sdr_soapy to owrx_connector
+- OSM maps instead of Google when google_maps_api_key is not set (thanks @jquagga)
+- Improved logic to pass parameters to soapy devices.
+  - `rtl_sdr_soapy`: added support for `bias_tee`
+  - `sdrplay`: added support for `bias_tee`, `rf_notch` and `dab_notch`
+  - `airspy`: added support for `bitpack`
+- Added support for Perseus-SDR devices, (thanks @amontefusco)
+- Property System has been rewritten so that defaults on sdr behave as expected
+- Waterfall range auto-adjustment now only takes the center 80% of the spectrum into account, which should work better
+  with SDRs that oversample or have rather flat filter curves towards the spectrum edges
+- Bugfix for negative network usage
+- FiFi SDR: prevent arecord from shutting down after 2GB of data has been sent
+- Added support for bias tee control on rtl_sdr devices
+- All connector driven SDRs now support `"rf_gain": "auto"` to enable AGC
+- `rtl_sdr` type now also supports the `direct_sampling` option
+- Added decoding implementation for for digimode "JS8Call"
+  (requires an installation of [js8call](http://js8call.com/) and
+  [the js8py library](https://github.com/jketterl/js8py))
+- Reorganization of the frontend demodulator code
+- Improve receiver load time by concatenating javascript assets
+- Docker images migrated to Debian slim images; This was necessary to allow the use of function multiversioning in
+  csdr and owrx_connector to allow the images to run on a wider range of CPUs
+- Docker containers have been updated to include the SDRplay driver version 3
+- HackRF support is now based on SoapyHackRF
+- Removed sdr.hu server listing support since the site has been shut down
+- Added support for Radioberry 2 Rasbperry Pi SDR Cape
+
+**0.18.0**
+- Support for SoapyRemote
+
+**2020-02-08**
+- Compression, resampling and filtering in the frontend have been rewritten in javascript, sdr.js has been removed
+- Decoding of Pocsag modulation is now possible
+- Removed the 3D waterfall since it had no real application and required ~1MB of javascript code to be downloaded
+- Improved the frontend handling of the "too many users" scenario
+- PSK63 digimode is now available (same decoding pipeline as PSK31, but with adopted parameters)
+- The frequency can now be manipulated with the mousewheel, which should allow the user to tune more precise. The tuning
+  step size is determined by the digit the mouse cursor is hovering over.
+- Clicking on the frequency now opens an input for direct frequency selection
+- URL hashes have been fixed and improved: They are now updated automatically, so a shared URL will include frequency
+  and demodulator, which allows for improved sharing and linking.
+- New daylight scheduler for background decoding, allows profiles to be selected by local sunrise / sunset times
+- New devices supported:
+  - LimeSDR (`"type": "lime_sdr"`)
+  - PlutoSDR (`"type": "pluto_sdr"`)
+  - RTL_SDR via Soapy (`"type": "rtl_sdr_soapy"`) on special request to allow use of the direct sampling mode
+
+**2020-01-04**
+- The [owrx_connector](https://github.com/jketterl/owrx_connector) is now the default way of communicating with sdr
+  devices. The old sdr types have been replaced, all `_connector` suffixes on the type must be removed!
+- The sources have been refactored, making it a lot easier to add support for other devices
+- SDR device failure handling has been improved, including user feedback
+- New devices supported:
+  - FiFiSDR (`"type": "fifi_sdr"`)
+
+**2019-12-15**
+- wsjt-x updated to 2.1.2
+- The rtl_tcp compatibility mode of the owrx_connector is now configurable using the `rtltcp_compat` flag
+
+**2019-12-10**
+- added support for airspyhf devices (Airspy HF+ / Discovery)
+
+**2019-12-05**
+- explicit device filter for soapy devices for multi-device setups
+
+**2019-12-03**
+- compatibility fixes for safari browsers (ios and mac)
+
+**2019-11-24**
+- There is now a new way to interface with SDR hardware, .
+  They talk directly to the hardware (no rtl_sdr / rx_sdr necessary) and offer I/Q data on a socket, just like nmux
+  did before. They additionally offer a control socket that allows openwebrx to control the SDR parameters directly,
+  without the need for repeated restarts. This allows for quicker profile changes, and also reduces the risk of your
+  SDR hardware from failing during the switchover. See `config_webrx.py` for further information and instructions.
+- Offset tuning using the `lfo_offset` has been reworked in a way that `center_freq` has to be set to the frequency you
+  actually want to listen to. If you're using an `lfo_offset` already, you will probably need to change its sign.
+- `initial_squelch_level` can now be set on each profile.
+- As usual, plenty of fixes and improvements.
+
+**2019-10-27**
+- Part of the frontend code has been reworked
+  - Audio buffer minimums have been completely stripped. As a result, you should get better latency. Unfortunately,
+    this also means there will be some skipping when audio starts.
+  - Now also supports AudioWorklets (for those browser that have it). The Raspberry Pi image has been updated to include
+    https due to the SecureContext requirement.
+  - Mousewheel controls for the receiver sliders
+- Error handling for failed SDR devices
+
+**2019-09-29**
+- One of the most-requested features is finally coming to OpenWebRX: Bookmarks (sometimes also referred to as labels).
+  There's two kinds of bookmarks available:
+  - Serverside bookmarks that are set up by the receiver administrator. Check the file `bookmarks.json` for examples!
+  - Clientside bookmarks which every user can store for themselves. They are stored in the browser's localStorage.
+- Some more bugs in the websocket handling have been fixed.
+
+**2019-09-25**
+- Automatic reporting of spots to [pskreporter](https://pskreporter.info/) is now possible. Please have a look at the
+  configuration on how to set it up.
+- Websocket communication has been overhauled in large parts. It should now be more reliable, and failing connections
+  should now have no impact on other users.
+- Profile scheduling allows to set up band-hopping if you are running background services.
+- APRS now has the ability to show symbols on the map, if a corresponding symbol set has been installed. Check the
+  config!
+- Debug logging has been disabled in a handful of modules, expect vastly reduced output on the shell.
+
+**2019-09-13**
+- New set of APRS-related features
+  - Decode Packet transmissions using [direwolf](https://github.com/wb2osz/direwolf) (1k2 only for now)
+  - APRS packets are mostly decoded and shown both in a new panel and on the map
+  - APRS is also available as a background service
+  - direwolfs I-gate functionality can be enabled, which allows your receiver to work as a receive-only I-gate for the
+    APRS network in the background
+- Demodulation for background services has been optimized to use less total bandwidth, saving CPU
+- More metrics have been added; they can be used together with collectd and its curl_json plugin for now, with some
+  limitations.
+
+**2019-07-21**
+- Latest Features:
+  - More WSJT-X modes have been added, including the new FT4 mode
+  - I started adding a bandplan feature, the first thing visible is the "dial" indicator that brings you right to the
+    dial frequency for digital modes
+  - fixed some bugs in the websocket communication which broke the map
+
+**2019-07-13**
+- Latest Features:
+  - FT8 Integration (using wsjt-x demodulators)
+  - New Map Feature that shows both decoded grid squares from FT8 and Locations decoded from YSF digital voice
+  - New Feature report that will show what functionality is available
+- There's a new Raspbian SD Card image available (see below)
+
+**2019-06-30**
+- I have done some major rework on the openwebrx core, and I am planning to continue adding more features in the near
+  future. Please check this place for updates.
+- My work has not been accepted into the upstream repository, so you will need to chose between my fork and the official
+  version.
+- I have enabled the issue tracker on this project, so feel free to file bugs or suggest enhancements there!
+- This version sports the following new and amazing features:
+  - Support of multiple SDR devices simultaneously
+  - Support for multiple profiles per SDR that allow the user to listen to different frequencies
+  - Support for digital voice decoding
+  - Feature detection that will disable functionality when dependencies are not available (if you're missing the digital
+    buttons, this is probably why)
+- Raspbian SD Card Images and Docker builds available (see below)
+- I am currently working on the feature set for a stable release, but you are more than welcome to test development
+  versions!

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see

 ## Setup
 
-OpenWebRX currently requires Linux and python 2.7 to run. 
+The following methods of setting up a receiver are currently available:
 
-First you will need to install the dependencies:
+- Raspberry Pi SD card images
+- Debian repository
+- Docker images
+- Manual installation
 
-- <a href="https://github.com/simonyiszk/csdr">libcsdr</a>
-- <a href="http://sdr.osmocom.org/trac/wiki/rtl-sdr">rtl-sdr</a>
+Please checkout the [setup guide on the wiki](https://github.com/jketterl/openwebrx/wiki/Setup-Guide) for more details
+on the respective methods.
 
-After cloning this repository and connecting an RTL-SDR dongle to your computer, you can run the server:
+## Community
 
-	python openwebrx.py
-
-You can now open the GUI at <a href="http://localhost:8073">http://localhost:8073</a>.
-
-Please note that the server is also listening on the following ports (on localhost only):
-
-- port 8888 for the I/Q source,
-- port 4951 for the multi-user I/Q server.
-
-Now the next step is to customize the parameters of your server in `config_webrx.py`.
-
-Actually, if you do something cool with OpenWebRX (or just have a problem), please drop me a mail:  
-*Andras Retzler, HA7ILM &lt;randras@sdr.hu&gt;*

 However, if you hold down the shift key, you can drag the center line (BFO) or the whole passband (PBS).
 
-## Configuration tips
+## Licensing
 
-If you want to run OpenWebRX on a remote server instead of localhost, do not forget to set *server_hostname* in `config_webrx.py`, or you may get a WebSocket error.
+OpenWebRX is available under Affero GPL v3 license
+([summary](https://tldrlegal.com/license/gnu-affero-general-public-license-v3-(agpl-3.0))).
 
-DSP CPU usage can be fine-tuned in `plugins/dsp/csdr/plugin.py`: you can set transition bandwidths higher (thus degrade filter performance by decreasing the length of the kernel, but also decrease CPU usage), and also set `fft_size` lower.
-
-If you constantly get *audio overrun* errors, you may change `audio_buffer_maximal_length_sec` in `openwebrx.js` from the default 1.7 to 3.
-
-If you want a chat-box to the top of the page, <a href="https://gist.github.com/ha7ilm/15c4c5e4c80cef9b3144">here is a snippet</a> for you to include in `config_webrx.py`.
-
-## Todo
-
-Currently, clients use up a lot of bandwidth. This will be improved later.
+OpenWebRX is also available under a commercial license on request. Please contact me at the address

+openwebrx (0.19.0) buster focal; urgency=low
+  * Fix direwolf connection setup by implementing a retry loop
+  * Pass direct sampling mode changes for rtl_sdr_soapy to owrx_connector
+  * OSM maps instead of Google when google_maps_api_key is not set (thanks
+    @jquagga)
+  * Improved logic to pass parameters to soapy devices.
+    - `rtl_sdr_soapy`: added support for `bias_tee`
+    - `sdrplay`: added support for `bias_tee`, `rf_notch` and `dab_notch`
+    - `airspy`: added support for `bitpack`
+  * Added support for Perseus-SDR devices, (thanks @amontefusco)
+  * Property System has been rewritten so that defaults on sdr behave as
+    expected
+  * Waterfall range auto-adjustment now only takes the center 80% of the
+    spectrum into account, which should work better with SDRs that oversample
+    or have rather flat filter curves towards the spectrum edges
+  * Bugfix for negative network usage
+  * FiFi SDR: prevent arecord from shutting down after 2GB of data has been
+    sent
+  * Added support for bias tee control on rtl_sdr devices
+  * All connector driven SDRs now support `"rf_gain": "auto"` to enable AGC
+  * `rtl_sdr` type now also supports the `direct_sampling` option
+  * Added decoding implementation for for digimode "JS8Call" (requires an
+    installation of js8call and the js8py library)
+  * Reorganization of the frontend demodulator code
+  * Improve receiver load time by concatenating javascript assets
+  * HackRF support is now based on SoapyHackRF
+  * Removed sdr.hu server listing support since the site has been shut down
+  * Added support for Radioberry 2 Rasbperry Pi SDR Cape

+
+openwebrx (0.18.0) buster; urgency=low
+
+  * Compression, resampling and filtering in the frontend have been rewritten
+    in javascript, sdr.js has been removed
+  * Decoding of Pocsag modulation is now possible
+  * Removed the 3D waterfall since it had no real application and required ~1MB
+    of javascript code to be downloaded
+  * Improved the frontend handling of the "too many users" scenario
+  * PSK63 digimode is now available (same decoding pipeline as PSK31, but with
+    adopted parameters)
+  * The frequency can now be manipulated with the mousewheel, which should
+    allow the user to tune more precise. The tuning step size is determined by
+    the digit the mouse cursor is hovering over.
+  * Clicking on the frequency now opens an input for direct frequency selection
+  * URL hashes have been fixed and improved: They are now updated
+    automatically, so a shared URL will include frequency and demodulator,
+    which allows for improved sharing and linking.
+  * New daylight scheduler for background decoding, allows profiles to be
+    selected by local sunrise / sunset times
+  * The owrx_connector is now the default way of communicating with sdr
+    devices. The old sdr types have been replaced, all `_connector` suffixes on
+    the type must be removed!
+  * The sources have been refactored, making it a lot easier to add support for
+    other devices
+  * SDR device failure handling has been improved, including user feedback
+  * New devices supported:
+  * wsjt-x updated to 2.1.2
+  * The rtl_tcp compatibility mode of the owrx_connector is now configurable
+    using the `rtltcp_compat` flag
+  * explicit device filter for soapy devices for multi-device setups
+  * compatibility fixes for safari browsers (ios and mac)
+  * Offset tuning using the `lfo_offset` has been reworked in a way that
+    `center_freq` has to be set to the frequency you actually want to listen
+    to. If you're using an `lfo_offset` already, you will probably need to
+    change its sign.
+  * `initial_squelch_level` can now be set on each profile.
+  * Part of the frontend code has been reworked
+    - Audio buffer minimums have been completely stripped. As a result, you
+      should get better latency. Unfortunately, this also means there will be
+      some skipping when audio starts.
+    - Now also supports AudioWorklets (for those browser that have it).
+    - Mousewheel controls for the receiver sliders
+  * Error handling for failed SDR devices
+  * One of the most-requested features is finally coming to OpenWebRX:
+    Bookmarks (sometimes also referred to as labels).
+    There's two kinds of bookmarks available:
+    - Serverside bookmarks that are set up by the receiver administrator.
+      Check the file `bookmarks.json` for examples!
+    - Clientside bookmarks which every user can store for themselves. They are
+      stored in the browser's localStorage.
+  * Automatic reporting of spots to [pskreporter](https://pskreporter.info/) is
+    now possible. Please have a look at the configuration on how to set it up.
+  * Websocket communication has been overhauled in large parts. It should now
+    be more reliable, and failing connections should now have no impact on
+    other users.
+  * Profile scheduling allows to set up band-hopping if you are running
+    background services.
+  * APRS now has the ability to show symbols on the map, if a corresponding
+    symbol set has been installed. Check the config!
+  * Debug logging has been disabled in a handful of modules, expect vastly
+    reduced output on the shell.
+  * New set of APRS-related features
+    - Decode Packet transmissions using direwolf (1k2 only for now)
+    - APRS packets are mostly decoded and shown both in a new panel and on the
+      map
+    - APRS is also available as a background service
+    - direwolfs I-gate functionality can be enabled, which allows your receiver
+      to work as a receive-only I-gate for the APRS network in the background
+  * Demodulation for background services has been optimized to use less total
+    bandwidth, saving CPU
+  * More metrics have been added; they can be used together with collectd and
+    its curl_json plugin for now, with some limitations.
+  * New bandplan feature, the first thing visible is the "dial" indicator that
+    brings you right to the dial frequency for digital modes
+  * fixed some bugs in the websocket communication which broke the map
+  * WSJT-X integration (FT8, FT4, WSPR, JT65, JT9 using wsjt-x demodulators)
+  * New Map Feature that shows both decoded grid squares from FT8 and Locations
+    decoded from YSF digital voice
+  * New Feature report that will show what functionality is available
+  * major rework on the openwebrx core
+  * Support of multiple SDR devices simultaneously
+  * Support for multiple profiles per SDR that allow the user to listen to
+    different frequencies
+  * Support for digital voice decoding
+  * Feature detection that will disable functionality when dependencies are not
+    available (if you're missing the digital
+    buttons, this is probably why)
+  * Support added for the following SDR sources:
+    - LimeSDR (`"type": "lime_sdr"`)
+    - PlutoSDR (`"type": "pluto_sdr"`)
+    - RTL_SDR via Soapy (`"type": "rtl_sdr_soapy"`) on special request to allow
+      use of the direct sampling mode
+    - SoapyRemote (`"type": "soapy_remote"`)
+    - FiFiSDR (`"type": "fifi_sdr"`)
+    - airspyhf devices (Airspy HF+ / Discovery) (`"type": "airspyhf"`)

-with others.
-
-The OFL allows the licensed fonts to be used, studied, modified and
-redistributed freely as long as they are not sold by themselves. The
-fonts, including any derivative works, can be bundled, embedded, 
-redistributed and/or sold with any software provided that any reserved
-names are not used by derivative works. The fonts and derivatives,
-however, cannot be released under any other type of license. The
-requirement for fonts to remain under this license does not apply
-to any document created using the fonts or their derivatives.
