+Nageru 1.3.0, not released yet
+
+ - It is now possible, given enough CPU power (e.g., a quad-core Haswell or
+ faster desktop CPU), to output a stream that is suitable for streaming
+ directly to end users without further transcoding. In particular, this
+ includes support for encoding the network stream with x264 (the stream
+ saved to disk is still done using Quick Sync), for Metacube framing (for
+ streaming to the Cubemap reflector), and for choosing the network stream
+ mux. For more information, see the README.
+
+ - Add a flag (--disable-alsa-output) to disable ALSA monitoring output.
+
+ - Do texture uploads from the main thread instead of from separate threads;
+ may or may not improve stability with NVIDIA's proprietary drivers.
+
+ - When beginning a new video segment, the shutdown of the old encoder
+ is now done in a background thread, in order to not disturb the external
+ stream. The audio still goes into a somewhat random stream, though.
+
+ - You can now override the default stream-to-card mapping with --map-signal=
+ on the command line.
+
+ - Nageru now tries to lock itself into RAM if it has the permissions to do
+ so, for better realtime behavior. (Writing the stream to disk tends to
+ fill the buffer cache, eventually paging less-used parts of Nageru out.)
+
+ - Various fixes for deadlocks, memory leaks, and many other errors.
+
+
+Nageru 1.2.1, April 15th, 2016
+
+ - Images are now updated from disk about every second, so that it is possible
+ to update e.g. overlays during streaming, although somewhat slowly.
+
+ - Fix support for PNG images.
+
+ - You can now send SIGHUP to start a new cut instead of using the menu.
+
+ - Added a --help option.
+
+ - Various tweaks to OpenGL fence handling.
+
+
+Nageru 1.2.0, April 6th, 2016
+
+ - Support for Blackmagic's PCI and Thunderbolt cards, using the official
+ (closed-source) Blackmagic drivers. (You do not need the SDK installed, though.)
+ You can use PCI and USB cards pretty much interchangeably.
+
+ - Much more stable handling of frame queues on non-master cards. In particular,
+ you can have a master card on 50 Hz and another card on 60 Hz without getting
+ lots of warning messages and a 10+ frame latency on the second card.
+
+ - Many new options in the right click menu on cards: Adjustable video inputs,
+ adjustable audio inputs, adjustable resolutions, ability to select card for
+ master clock.
+
+ - Add support for starting with almost all audio processing turned off
+ (--flat-audio).
+
+ - The UI now marks inputs with red or green to mark them as participating in
+ the live or preview signal, respectively. Red takes priority. (Actually,
+ it merely asks the theme for a color for each input; the theme contains
+ the logic.)
+
+ - Add support for uncompressed video instead of H.264 on the HTTP server,
+ while still storing H.264 to files (--http-uncompressed-video). Note that
+ depending on your client, this might not actually be more CPU efficient
+ even on localhost, so be sure to check.
+
+ - Add a simpler, less featureful theme (simple.lua) that should be easier to
+ understand for beginners. Themes are now also choosable with -t on the command
+ line.
+
+ - Too many bugfixes and small tweaks to list. In particular, many memory leaks
+ in the streaming part have been identified and fixed.
+
+
+Nageru 1.1.0, February 24th, 2016
+
+ - Support doing the H.264 encoding on a different graphics device from the one
+ doing the mixing. In particular, this makes it possible to use Nageru on an
+ NVIDIA GPU while still encoding H.264 video using Intel Quick Sync (NVENC
+ is not supported yet) -- it is less efficient since the data needs to be read
+ back via the CPU, but the NVIDIA cards and drivers are so much faster that it
+ doesn't really matter. Tested on a GTX 950 with the proprietary drivers.
+
+ - In the included example theme, fix fading to/from deinterlaced sources.
+
+ - Various smaller compilation, distribution and documentation fixes.
+
