-**unreleased**
-- 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.

+# OpenWebRX
 
 OpenWebRX is a multi-user SDR receiver software with a web interface.
 
+----
+
+### ⚠️ From 2019-12-29 OpenWebRX development is discontinued. ⚠️
+
+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).

+**News (2015-08-18)**
+- 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.
+
+**News (2017-07-12)**
+- OpenWebRX now has a BPSK31 demodulator and a 3D waterfall display.
+
+> When upgrading OpenWebRX, please make sure that you also upgrade *csdr*!

+## 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.

 ## Setup
 
-### Raspberry Pi SD Card Images
-
-Probably the quickest way to get started is to download the latest Raspberry Pi SD Card Image. It contains all the
-depencencies out of the box, and should work on all Raspberry Pis. It is based off the Raspbian Lite distribution,
-so [their installation instructions](https://www.raspberrypi.org/documentation/installation/installing-images/) apply.
-
-You can find the latest images [here](https://s3.eu-central-1.amazonaws.com/de.dd5jfk.openwebrx/index.html). You can
-also checkout the `nightly` folder, which has the most recent builds, albeit untested.
-
-Once you have booted a Raspberry with the SD Card, it will appear in your network with the hostname "openwebrx", which
-should make it available as https://openwebrx/ on most networks. This may vary depending on your specific setup.
-
-For Digital voice, the minimum requirement right now seems to be a Rasbperry Pi 3B+. I would like to work on optimizing
-this for lower specs, but at this point I am not sure how much can be done. 
-
-### Docker Images
-
-For those familiar with docker, I am providing
-[recent builds and Releases for both x86 and arm processors on the Docker hub](https://hub.docker.com/r/jketterl/openwebrx).
-You can find a short introduction there.
-
-### Manual Installation
-
-OpenWebRX currently requires Linux and python >= 3.6 to run. 
+OpenWebRX currently requires Linux and python 2.7 to run. 
 
 First you will need to install the dependencies:
 
-- [csdr](https://github.com/jketterl/csdr)
-- [rtl-sdr](http://sdr.osmocom.org/trac/wiki/rtl-sdr)
-- [owrx_connector](https://github.com/jketterl/owrx_connector)
-
-Optional dependencies if you want to be able to listen do digital voice:
-
-- [digiham](https://github.com/jketterl/digiham)
-- [dsd](https://github.com/f4exb/dsdcc)
-
-Optional dependency if you want to decode WSJT-X modes:
-
-- [wsjt-x](https://physics.princeton.edu/pulsar/k1jt/wsjtx.html)
-
-[Detailed installation instructions in the Wiki](https://github.com/jketterl/openwebrx/wiki/Manual-Package-installation-(including-digital-voice))
+- <a href="https://github.com/simonyiszk/csdr">libcsdr</a>
+- <a href="http://sdr.osmocom.org/trac/wiki/rtl-sdr">rtl-sdr</a>
 
 After cloning this repository and connecting an RTL-SDR dongle to your computer, you can run the server:
 
-	./openwebrx.py
-	
+	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 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 (0.18.0) 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"`)

+-----------------------------------------------------------
+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+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
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+
+"Author" refers to any designer, engineer, programmer, technical
+writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+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.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
+distributed under any other license. The requirement for fonts to
+remain under this license does not apply to any document created
+using the Font Software.
+
+TERMINATION
+This license becomes null and void if any of the above conditions are
+not met.
