+Nageru 1.5.0, April 5th, 2017
+
+ - Support for low-latency HDMI/SDI output in addition to (or instead of) the
+ stream. This currently only works with DeckLink cards, not bmusb. See the
+ manual for more information.
+
+ - Support changing the resolution from the command line, instead of locking
+ everything to 1280x720.
+
+ - The A/V sync code has been rewritten to be more in line with Fons
+ Adriaensen's original paper. It handles several cases much better,
+ in particular when trying to match 59.94 and 60 Hz sources to each other.
+ However, it might occasionally need a few extra seconds on startup to
+ lock properly if startup is slow.
+
+ - Add support for using x264 for the disk recording. This makes it possible,
+ among other things, to run Nageru on a machine entirely without VA-API
+ support.
+
+ - Support for 10-bit Y'CbCr, both on input and output. (Output requires
+ x264 disk recording, as Quick Sync Video does not support 10-bit H.264.)
+ This requires compute shader support, and is in general a little bit
+ slower on input and output, due to the extra amount of data being shuffled
+ around. Intermediate precision is 16-bit floating-point or better,
+ as before.
+
+ - Enable input mode autodetection for DeckLink cards that support it.
+ (bmusb mode has always been autodetected.)
+
+ - Add functionality to add a time code to the stream; useful for debugging
+ latency.
+
+ - The live display is now both more performant and of higher image quality.
+
+ - Fix a long-standing issue where the preview displays would be too bright
+ when using an NVIDIA GPU. (This did not affect the finished stream.)
+
+ - Many other bugfixes and small improvements.
+
+
+Nageru 1.4.2, November 24th, 2016
+
+ - Fix a thread race that would sometimes cause x264 streaming to go awry.
+
+
+Nageru 1.4.1, November 6th, 2016
+
+ - Various bugfixes.
+
+
+Nageru 1.4.0, October 26th, 2016
+
+ - Support for multichannel (or more accurately, multi-bus) audio,
+ choosable from the UI or using the --multichannel command-line
+ flag. In multichannel mode, you can take in inputs from multiple
+ different sources (or different channels on the same source, for
+ multichannel sound cards), apply effects to them separately and then
+ mix them together. This includes both audio from the video cards
+ as well as ALSA inputs, including hotplug. Ola Gundelsby contributed
+ invaluable feedback on this feature throughout the entire
+ development cycle.
+
+ - Support for having MIDI controllers control various aspects of the
+ audio UI, with relatively flexible mapping. Note that different
+ MIDI controllers can vary significantly in what protocol they speak,
+ so Nageru will not necessarily work with all. (The primary testing
+ controller has been the Akai MIDImix, and a pre-made mapping for
+ that is included. The Korg nanoKONTROL2 has also been tested and
+ works, but it requires some Korg-specific SysEx commands to make
+ the buttons and lights work.)
+
+ - Add a disk space indicator to the main window.
+
+ - Various bugfixes. In particular, an issue where the audio would pitch
+ up sharply after a series of many dropped frames has been fixed.
+
+
+Nageru 1.3.4, August 2nd, 2016
+
+ - Various bugfixes.
+
+
+Nageru 1.3.3, July 27th, 2016
+
+ - Various changes to make distribution packaging easier; in particular,
+ theme data can be picked up from /usr/local/share/nageru.
+
+ - Fix various FFmpeg deprecation warnings, now that we need FFmpeg
+ 3.1 for other reasons anyway.
+
+
+Nageru 1.3.2, July 23rd, 2016
+
+ - Allow limited hotplugging (unplugging and replugging) of USB cards.
+ You can use the new command-line option --num-fake-cards (-C) to add
+ fake cards that show only a single color and that will be replaced
+ by real cards as you plug them in; you can also unplug cards and have
+ them be replaced by fake cards. Fake cards can also be used for testing
+ Nageru without actually having any video cards available.
+
+ - Add Metacube timestamping of every keyframe, for easier detection of
+ streams not keeping up. Works with the new timestamp feature of
+ Cubemap 1.3.1. Will be ignored (save for some logging) in older
+ Cubemap versions.
+
+ - The included default theme has been reworked and cleaned up to be
+ more understandable and extensible.
+
+ - Add more command-line options for initial audio setup.
+
+
+Nageru 1.3.1, July 1st, 2016
+
+ - Various display bugfixes.
+
+
+Nageru 1.3.0, June 26th, 2016
+
+ - 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.
+
