  * Fixed affine ox and oy properties incorrect with preview
    scaling.
  * Fixed a crash and incorrect preview scaling with more than
    one affine
    filter active on the same frame.
  * Fixed preview scaling for the rotoscoping filter.
  * Added the sample_fmt property to the avformat consumer.
  * Fixed a possible segfault in the mix transition.
  * Removed support for text keyframes to the text and qtext
    filters
    to fix regression on strings containing '='.

  * Fixed a crash with with filters not supporting preview scale
    in frei0r transitions.
  * Fix artifacts in luma transition and affine filter with
    frame-threading.
  * Stop including 'title="Anonymous Submission"' in xml
    consumer.
  * Fixed a crash in opencv.tracker filter.
  * Fixed a crash in composite transition if luma file fails to
    load.
  * Added validations in opengl module to prevent asserts in
    Movit.
  * Fixed building with OpenCV 4.
  * Moved some services from gtk2 module to new gdk module:
    gtkrescale filter, pango producer and pixbuf producer
  * Deprecated the gtk2 module and no longer enabled by default.
  * Changed avformat producer to accept a '?' in
    argument/resource property by escaping it as '\?'.
  * Changed the background property of the affine filter to be
    mutable.
  * Deprecated the linsys (DVEO SDI) module.
  * Fixed changing the audio_index property in the avformat
    producer.
  * Changed resample filter to more resiliant to frequency
    changes.
  * Added a video_delay property to the sdl2_audio and rtaudio
    consumers.
  * Add millisecond options to the timer filter.
  * Fixed the in point handling for the timewarp producer.
  * Fixed some audio gaps and sync issues with the rbpitch
    filter and timewarp pitch compensation.
  * Fixed a possible crash caused by producer consumer.
  * Changed avformat consumer to set AVOption color_primaries
    based on the MLT colorspace if not already set as property.
  * Fixed crop right on image with odd width skews image in crop
    filter.
  * Fixed incorrect silence value for unsigned 8-bit audio in
    avformat producer.
  * Changed qimage to use Qt's internal orientation detection
    instead of libexif.
  * Reduced clicks in mix transition by silencing buffers on
    discontinuity.
  * Improved A/V synchronization in (sw)resample filters - also
    reduces audio clicks.
  * Improved speed of the qimage producer.
  * Fixed incorrect color using libx264rgb in avformat consumer.
  * Fixed relative paths for avfilters that have the "filename"
    option.
  * Fixed some avfilters dropping the alpha channel: smartblur,
    vaguedenoiser.
  * Improved performance of the resize filter.
  * Fixed an affine filter inside a transition was always
    nearest neighbor interpolation.
  * Changed the lift_gamma_gain filter to use round values up.
  Other:
  * Fixed melt option "-group" applies to an implicit consumer.
  * Added "-quiet" option to melt (implies -silent but more so).
  * CMake build improvments adding modules: gdk, jackrack, lumas
    resample, sox and vorbis
  * Added avformat consumer presets: Slide-Deck-H264 and
    Slide-Deck-HEVC
  * Removed intra=1 from some avformat presets (use g=1 for
    intra only): intermediate/MPEG-2, intermediate/MPEG-4
