@@ -0,0 +1,150 @@
+**0.19.1**
+- Added ability to authenticate receivers with listing sites using "receiver id" tokens
+
+**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!

-First of all, thank you for taking the time to contribute to this project!
-
-Before I can accept your contributions, I need a signed copy of the Individual Contributor License Agreement (ICLA) from you, which is available <a href="ICLA.txt">here</a>.
-
-The ICLA is needed because it will allow me to dual license the OpenWebRX project under AGPL and a commercial license.
-I will also apply dual licensing to csdr, but only those parts that are original work (e.g. without the parts enabled by `-DUSE_IMA_ADPCM`; code taken from other projects is clearly separable).
-
-However, even if there is commercial interest in the projects, I promise to keep them as open as possible, keeping my original intention to provide an open-source web-based SDR receiver software to the amateur radio operators and SDR enthusiasts.
-
-This contributor agreement is based on the one of Apache Software Foundation, with some modifications. (You can review differences <a href="https://gist.github.com/ha7ilm/9e981006d24659e336c7/revisions">here</a>).
-When you contribute for the first time, I will send you the ICLA. Replying with only the information requested and the text "I Agree" is sufficient.

-
-I'm would like to say a big thanks to everyone who supported me during this project, including those who contributed either code or donations. It has been a very fruitful 6 years, but now it's time to move on to other projects. See also my [blog](https://blog.sdr.hu) about that.

-(@simonyiszk, please keep this GitHub repo for historic purposes.)
-
-Know limitations of the last version:
-
-- Python 2.7, a main dependency of the project, will be not be officially maintained from 1 January 2020. By time, probably it will not be secure to use this version on public servers, unless someone still provides security patches for Python 2. 
-- Some specific parts of the DSP code could be improved for better SNR.
-
-Even though these limitations are probably acceptable in an amateur radio project, I would not build critical infrastructure on it.  
-
-For commercial inquiries (e.g. if someone wants me to develop an improved version without these limitations), I'm still open, [drop me an e-mail](mailto:randras@sdr.hu).

-- My BSc. thesis written on OpenWebRX is <a href="https://sdr.hu/static/bsc-thesis.pdf">available here.</a>
-- Several bugs were fixed to improve reliability and stability.
-- OpenWebRX now supports compression of audio and waterfall stream, so the required network uplink bandwidth has been decreased from 2 Mbit/s to about 200 kbit/s per client! (Measured with the default settings. It is also dependent on `fft_size`.)
-- OpenWebRX now uses <a href="https://github.com/simonyiszk/csdr#sdrjs">sdr.js</a> (*libcsdr* compiled to JavaScript) for some client-side DSP tasks. 
-- Receivers can now be listed on <a href="http://sdr.hu/">SDR.hu</a>.
-- License for OpenWebRX is now Affero GPL v3. 
-
-**News (2016-02-14)**
-- The DDC in *csdr* has been manually optimized for ARM NEON, so it runs around 3 times faster on the Raspberry Pi 2 than before. 
-- Also we use *ncat* instead of *rtl_mus*, and it is 3 times faster in some cases.
-- OpenWebRX now supports URLs like: `http://localhost:8073/#freq=145555000,mod=usb`
-- UI improvements were made, thanks to John Seamons and Gnoxter.
-
-**News (2017-04-04)**
-- *ncat* has been replaced with a custom implementation called *nmux* due to a bug that caused regular crashes on some machines. The *nmux* tool is part of the *csdr* package.
-- Most consumer SDR devices are supported via <a href="https://github.com/rxseger/rx_tools">rx_tools</a>, see the <a href="https://github.com/simonyiszk/openwebrx/wiki/Using-rx_tools-with-OpenWebRX">OpenWebRX Wiki</a> on that.

-## OpenWebRX servers on SDR.hu
-
-[SDR.hu](http://sdr.hu) is a site which lists the active, public OpenWebRX servers. Your receiver [can also be part of it](http://sdr.hu/openwebrx), if you want.
-
-![sdr.hu](http://blog.sdr.hu/images/openwebrx/screenshot-sdrhu.png)
 
 ## 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>
+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
+If you have trouble setting up or configuring your receiver, you have some great idea you want to see implemented, or
-
+you just generally want to have some OpenWebRX-related chat, come visit us over on
-You can now open the GUI at <a href="http://localhost:8073">http://localhost:8073</a>.
+[our groups.io group](https://groups.io/g/openwebrx).
-
-Please note that the server is also listening on the following ports (on localhost only):
-
-- 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`.

+openwebrx (0.19.1) buster focal; urgency=low
+
+  * Added ability to authenticate receivers with listing sites using
+    "receiver id" tokens
+
+ -- Jakob Ketterl <jakob.ketterl@gmx.de>  Sat, 13 Jun 2020 16:46:00 +0000
+
+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"`)

------------------------------------------------------------
-
-PREAMBLE
-The goals of the Open Font License (OFL) are to stimulate worldwide
-development of collaborative font projects, to support the font creation
-efforts of academic and linguistic communities, and to provide a free and
-open framework in which fonts may be shared and improved in partnership
-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.
-
-DEFINITIONS
-"Font Software" refers to the set of files released by the Copyright
-Holder(s) under this license and clearly marked as such. This may
-include source files, build scripts and documentation.
-
-"Reserved Font Name" refers to any names specified as such after the
-copyright statement(s).
-
-"Original Version" refers to the collection of Font Software components as

-binary files as long as those fields can be easily viewed by the user.
-
-3) No Modified Version of the Font Software may use the Reserved Font
-Name(s) unless explicit written permission is granted by the corresponding
-Copyright Holder. This restriction only applies to the primary font name as
-presented to the users.
