+Nageru and Futatabi 1.9.3, April 12th, 2020
+
+ - Support (video-only) V4L2 output. The intended use case is output into
+ v4l2loopback to get into videoconferencing or the likes:
+
+ sudo apt install v4l2loopback-dkms
+ sudo modprobe v4l2loopback video_nr=2 card_label='Nageru loopback' max_width=1280 max_height=720 exclusive_caps=1
+ nageru --v4l-output /dev/video2
+
+ Start Nageru before any readers.
+
+
+Nageru and Futatabi 1.9.2, March 29th, 2020
+
+ - Support handling white balance directly in Nageru, without themes
+ manually inserting a WhiteBalanceEffect or handling set_wb().
+ To use it, call scene:add_white_balance() instead of
+ scene:add_effect(WhiteBalanceEffect.new()). If using this functionality,
+ white balance will be properly propagated to the MJPEG feed and
+ through Futatabi, so that replays get the correct white balance.
+ Futatabi's UI will still be uncorrected, though.
+
+ - Make it possible to siphon out a single MJPEG stream, for remote
+ debugging, single-camera recording, single-camera streaming via
+ Kaeru or probably other things. The URL for this is /feeds/N.mp4
+ where N is the card index (starting from zero).
+
+ - The theme can now access some audio settings; it can get (not set)
+ number of buses and names, get/set fader volume, get/set mute,
+ and get/set EQ parameters.
+
+ - In Futatabi, it is now possible to set custom source labels, with
+ the parameter --source-label NUM:LABEL (or -l NUM:LABEL).
+
+ - When the playback speed changes in Futatabi, ease into the new speed.
+ The easing period is nominally 200 ms, but it will be automatically
+ shortened or lengthened (up to as much as two seconds in extreme
+ cases, especially involving very slight speed change) if this
+ helps getting back into a cadence of hitting the original frames.
+ This can mean significant performance improvements when ramping
+ from higher speeds back into 100%.
+
+ - Updates for newer versions of CEF (tested with Chrome 80).
+
+ - Various bugfixes and performance improvements.
+
+
+Nageru and Futatabi 1.9.1, November 17th, 2019
+
+ - Support disabling optional effects if a given other effect is _enabled_
+ (typically for mutually exclusive effects).
+
+ - Make it possible for the theme to override the status line, by declaring
+ a function format_status_line() in the theme. Inspired by a C++ patch by
+ Alex Thomazo in the Breizhcamp repository.
+
+ - Various bugfixes.
+
+
+Nageru and Futatabi 1.9.0, July 20th, 2019
+
+ - Significant reworking of the theme engine: Chains (now called scenes)
+ can now instantiate different versions behind-the-scenes instead of the
+ user having to worry about input types, low/high quality, or replacing
+ effects with others. Menus can have submenus and checkboxes. Finally, some
+ callbacks, such as num_channels(), have been replaced with easier-to-use
+ imperative functions, ie., an explicit call to Nageru.set_num_channels(N).
+
+ See the documentation for more information, or the included themes,
+ which have been ported to the new interfaces. Existing themes will continue
+ to run without modification, but the old interfaces are deprecated.
+
+ Martin Sandsmark contributed a bugfix to this work.
+
+ - Support cross-compilation. Patch from Helmut Grohne.
+
+ - Kaeru now has a parameter --disable-audio for transcoding streams
+ with no audio.
+
+ - Various bugfixes. In particular, work around an issue where Mesa's shader
+ cache interacts with Qt's EGL support to create a confusing crash with
+ “vertex shader lacks `main'”.
+
+
+Nageru and Futatabi 1.8.6, April 19th, 2019
+
+ - Filenames for the recordings are now without colons; it caused
+ too much problems with various software, including most players.
+
+ - Various bugfixes.
+
+
+Nageru and Futatabi 1.8.5, March 30th, 2019
+
+ - Experimental support for audio in Futatabi: The MJPEG export from
+ Nageru now supports audio, and Futatabi will store it and play it
+ back. Audio is currently only supported when playing at 100% speed
+ (no pitch shift or time stretching), and there is no audio output
+ to the Futatabi operator.
+
+ - Significant optimizations to MJPEG encoding, both when in use and when
+ not in use.
+
+ - Various bugfixes.
+
+
+Nageru and Futatabi 1.8.4, March 11th, 2019
+
+ - Various bugfixes, in particular for 32-bit platforms.
+
+
+Nageru and Futatabi 1.8.3, March 10th, 2019
+
+ - Allow controlling video mixing from MIDI events. Adapted from a patch
+ by Yann Dubreuil, from the BreizhCamp repository.
+
+ - Use ALSA hardware timestamps for input; gives more stable delay.
+ Patch by Yann Dubreuil, from the BreizhCamp repository.
+
+ - For FFmpeg inputs, add an option for playing as fast as possible
+ (set rate >= 10.0).
+
+ - In Futatabi, support queueing and playing clips with no cue-out point.
+ This opens up for new and even faster UI workflows.
+
+ - Many bugfixes.
+
+
+Nageru and Futatabi 1.8.2, January 19th, 2019
+
+ - Futatabi now supports MIDI controllers like Nageru, including an editor
+ and a sample mapping for the Behringer CMD PL-1.
+
+ - Futatabi now supports changing master speed during play, both via a
+ MIDI controller and the GUI.
+
+ - Various bugfixes.
+
+
+Nageru and Futatabi 1.8.1, December 30th, 2018
+
+ - Futatabi can now communicate its queue status through a subtitle track,
+ and Nageru can consume it. This allows Nageru themes to get precise
+ information programmatically, e.g. to show status or automatically
+ switch away when the queue is about to end.
+
+ - Futatabi can now reuse the computed flow across successive frames when
+ interpolating between the same frame pair. This significantly reduces
+ the GPU load when doing super-slow motion (slower than 0.5x).
+
+ - Various smaller fixes.
+
+
+Nageru and Futatabi 1.8.0, December 20th, 2018
+
+ - Initial release of Futatabi, a multicamera slow motion video server
+ designed to be used with Nageru. Futatabi is currently in alpha stage
+ and largely undocumented.
+
+ - Add support for multi-camera export from Nageru. A multi-camera stream
+ contains all frames from all camera inputs (unless overridden by
+ --mjpeg-export-cards), unprocessed except for MJPEG encoding.
+ MJPEG encoding is done in hardware (via VA-API) on Skylake or newer,
+ or using libjpeg otherwise. The intended user of this stream is Futatabi.
+
+
Nageru 1.7.5, November 11th, 2018
- Fix a bug where --record-x264-video would not work when VA-API was
