+Nageru 1.7.2, April 28th, 2018
+
+ - Several improvements to video (FFmpeg) inputs: You can now use
+ them as audio sources, you can right-click on video channels
+ to change URL/filename on-the-fly, themes can ask for forced
+ disconnection (useful for network sources that are hanging),
+ and various other improvements. Be aware that the audio support
+ may still be somewhat rough, as A/V sync of arbitrary video
+ playout is a hard problem.
+
+ - The included themes have been fixed to properly make the returned
+ chain preparation functions independent of global state (e.g. if
+ the white balance for a channel was changed before the frame was
+ actually rendered). If you are using a custom theme, you may want
+ to apply similar fixes to it.
+
+ - In Metacube stream output, mark each keyframe with a pts metadata
+ block. This allows Cubemap 1.4.0 or newer to serve fMP4 fragments
+ for HLS from Nageru's output, without any further remuxing or
+ transcoding.
+
+ - If needed, Nageru will now automatically try to autodetect a
+ usable --va-display parameter by probing all DRM nodes for H.264
+ encoders. This removes the need to set --va-display in almost all
+ cases, and also removes the dependency on libpci.
+
+ - For GPUs that support querying available memory (in practice only
+ NVIDIA GPUs at the current time), expose the amount of used/total
+ GPU memory both on standard output and in the Prometheus metrics
+ (as well as included Grafana dashboard).
+
+ - The Grafana dashboard now supports heatmaps for the chosen x264
+ speedcontrol preset (requires Grafana 5.1 or newer). (There used to
+ be a heatmap earlier, but it was all broken.)
+
+ - Various bugfixes.
+
+
+Nageru 1.7.1, March 26th, 2018
+
+ - Various bugfixes, mostly related to HTML and video inputs.
+
+
+Nageru 1.7.0, March 8th, 2018
+
+ - Support for HTML5 graphics directly in Nageru, through CEF
+ (Chromium Embedded Framework). This performs better and is more
+ flexible than integrating with CasparCG over a socket. Note that
+ CEF is an optional component; see the documentation for more
+ information.
+
+ - Add an HTTP endpoint for enumerating channels and one for getting
+ only their colors. Intended for remote tally applications;
+ set the documentation.
+
+ - Add a video grid display that removes the audio controls and shows
+ the video channels only, potentially in multiple rows if that makes
+ for a larger viewing area.
+
+ - Themes can now present simple menus in the Nageru UI. See the
+ documentation for more information.
+
+ - Various bugfixes.
+
+
+Nageru 1.6.4, January 25th, 2018
+
+ - Fix compilation with the upcoming FFmpeg 3.5.
+
+ - Switch to LuaJIT for the theme engine, which is faster.
+
+ - Various bugfixes and smaller optimizations.
+
+
+Nageru 1.6.3, November 8th, 2017
+
+ - Add quick-cut keys (Q, W, E, etc.) below the preview keys.
+ Since it's easy to hit these by accident and put up a signal
+ you didn't want, they are disabled by default (they can be
+ enabled in the video menu, or with the command line flag
+ --quick-cut-keys).
+
+ - Rework the x264 speedcontrol presets to better match newer
+ x264 versions.
+
+ - Add an option for changing the HTTP port (--http-port).
+
+ - Various smaller bug and integration fixes.
+
+
+Nageru 1.6.2, July 16th, 2017
+
+ - Various smaller Kaeru fixes, mostly around metrics. Also,
+ you can now adjust the x264 bitrate in Kaeru (in 100 kbit/sec
+ increments) by sending SIGUSR1 (higher) or SIGUSR2 (lower).
+
+
+Nageru 1.6.1, July 9th, 2017
+
+ - Add native export of Prometheus metrics.
+
+ - Rework the frame queue drop algorithm. The new one should handle tricky
+ situations much better, especially when a card is drifting very slowly
+ against the master timer.
+
+ - Add Kaeru, an experimental transcoding tool based on Nageru code.
+ Kaeru can run headless on a server without a GPU to transcode a
+ Nageru stream into a lower-bitrate one, replacing VLC.
+
+ - Work around a bug in some versions of NVIDIA's OpenGL drivers that would
+ crash Nageru after about three hours (fix in cooperation with Movit).
+
+ - Fix a crash with i965-va-driver 1.8.x.
+
+ - Reduce mutex contention in certain critical places, causing lower tail
+ latency in the mixer.
+
+
+Nageru 1.6.0, May 29th, 2017
+
+ - Add support for having videos (from file or from URL) as a separate
+ input channels, albeit with some limitations. Apart from the obvious use of
+ looping pause clips or similar, this can be used to integrate with CasparCG;
+ see the manual for more details.
+
+ - Add a frame analyzer (accessible from the Video menu) containing an
+ RGB histogram and a color dropped tool. This is useful in calibrating
+ video chains by playing back a known signal. Note that this adds a
+ dependency on QCustomPlot.
+
+ - Allow overriding Y'CbCr input interpretation, for inputs that don't
+ use the correct settings. Also, Rec. 601 is now used by default instead
+ of Rec. 709 for SD resolutions.
+
+ - Support other sample rates than 48000 Hz from bmusb.
+
+
Nageru 1.5.0, April 5th, 2017
- Support for low-latency HDMI/SDI output in addition to (or instead of) the
