-Version 2.4.0:
+Version 3.0.0 (Feb 10, 2018):
+ * Major overhaul of the SDR input code - now it's modular and
+   hardware-agnostic (no longer tightly coupled with librtlsdr).
+ * Support for SoapySDR vendor-neutral SDR library - any SDR which has
+   a plugin for SoapySDR shall now work in RTLSDR-Airband.
+ * Support for Mirics DVB-T dongles via libmirisdr-4 library.
+ * Support for RTLSDR is now optional and can be disabled at compilation
+   stage.
+ * Removed the 8-channels-per-device limit in multichannel mode.
+ * Configurable per-device sampling rate.
+ * Configurable FFT size.
+ * Support for multibyte input samples.
+ * Support for rawfile outputs (ie. writing raw I/Q data from a
+   narrowband channel to a file for processing with other programs,
+   line GNUradio or csdr).
+ * INCOMPATIBLE CHANGE: removed `rtlsdr_buffers` global configuration
+   option; buffer count can now be adjusted with a per-device
+   "buffers" option.
+ * INCOMPATIBLE CHANGE: removed `syslog` global configuration option;
+   syslog logging is now enabled by default, both in foreground and
+   background mode. To force logging to standard error, use -e command
+   line option.
+ * Added -F command line option for better cooperation with systemd.
+   Runs the program in foreground, but without textual waterfalls.
+   Together with -e it allows running rtl_airband as a service of type
+   "simple" under systemd. Example rtl_airband.service file has been
+   adjusted to reflect this change.
+ * Added `type` device configuration option. It sets the device type
+   (ie. the input driver which shall be used to talk to the device).
+   "rtlsdr" is assumed as a default type for backward compatibility.
+   If RTLSDR support has been disabled at compilation stage, then
+   there is no default type - it must be set manually, or the program
+   will throw an error on startup.
+ * Frequencies in the config can now be expressed in Hz, kHz, MHz or GHz
+   for improved readability.
+ * Lots of bugfixes.
+ * Rewritten documentation on [Github Wiki](https://github.com/szpajder/RTLSDR-Airband/wiki).

+Version 2.4.0 (Oct 15, 2017):

  * Support for Icecast stream metadata updates in scanning mode. When enabled,
    every time the scanner stops on a channel, current frequency is written into
    Icecast song title, which in turn is displayed in the player. Alternatively,
    textual labels can be configured for each frequency. It is possible
