+- Improve DMABuf's usage, both upstream and dowstream, and
+ memory:DMABuf caps feature is also negotiated when the dmabuf-based
+ buffer cannot be mapped onto user-space.
+
+- VA initialization was fixed when it is used in headless systems.
+
+- VA display sharing, through GstContext, among the pipeline, has been
+ improved, adding the possibility to the application share its VA
+ display (external display) via gst.vaapi.app.Display context.
+
+- VA display cache was removed.
+
+- libva's log messages are now redirected into the GStreamer log
+ handler.
+
+- Decoders improved their upstream re-negotiation by avoiding to
+ re-instantiate the internal decoder if stream caps are compatible
+ with the previous one.
+
+- When downstream doesn't support GstVideoMeta and the decoded frames
+ don't have standard strides, they are copied onto system
+ memory-based buffers.
+
+- H.264 decoder has a low-latency property, for live streams which
+ doesn't conform the H.264 specification but still it is required to
+ push the frames to downstream as soon as possible.
+
+- As part of the Google Summer of Code 2017 the H.264 decoder drops
+ MVC and SVC frames when base-only property is enabled.
+
+- Added support for libva-2.0 (VA-API 1.0).
+
+- H.264 and H.265 encoders handle Region-Of-Interest metas by adding a
+ delta-qp for every rectangle within the frame specified by those
+ metas.
+
+- Encoders for H.264 and H.265 set the media profile by the downstream
+ caps.
+
+- H.264 encoder inserts an AU delimiter for each encoded frame when
+ aud property is enabled (it is only available for certain drivers
+ and platforms).
+
+- H.264 encoder supports for P and B hierarchical prediction modes.
+
+- All encoders handles a quality-level property, which is a number
+ from 1 to 8, where a lower number means higher quality, but slower
+ processing, and vice-versa.
+
+- VP8 and VP9 encoders support constant bit-rate mode (CBR).
+
+- VP8, VP9 and H.265 encoders support variable bit-rate mode (VBR).
+
+- Resurrected GstGLUploadTextureMeta handling for EGL backends.
+
+- H.265 encoder can configure its number of reference frames via the
+ refs property.
+
+- Add H.264 encoder mbbrc property, which controls the macro-block
+ bitrate as auto, on or off.
+
+- Add H.264 encoder temporal-levels property, to select the number of
+ temporal levels to be included.
+
+- Add to H.264 and H.265 encoders the properties qp-ip and qp-ib, to
+ handle the QP (quality parameter) difference between the I and P
+ frames, and the I and B frames, respectively.
+
+- vaapisink was demoted to marginal rank on Wayland because COGL
+ cannot display YUV surfaces.
