- New upstream release 3.7.0

 - New Features

 * New codec controls:

 * AV1E_SET_QUANTIZER_ONE_PASS: Set quantizer for each frame.
 * AV1E_ENABLE_RATE_GUIDE_DELTAQ: enable the rate distribution guided delta
 quantization in all intra mode. The 'enable-rate-guide-deltaq' option is
 added for this control.
 * AV1E_SET_RATE_DISTRIBUTION_INFO: set the input file for rate
 distribution used in all intra mode. The 'rate-distribution-info' option
 is added for this control.
 * AV1E_GET_LUMA_CDEF_STRENGTH
 * AV1E_SET_BITRATE_ONE_PASS_CBR

 * AOM_SCALING_MODE is extended to include 2/3 and 1/3 scaling.
 * aom_tune_metric is extended to include AOM_TUNE_VMAF_SALIENCY_MAP.
 The 'tune' option is extended to include 'vmaf_saliency_map'.
 * SVC example encoder svc_encoder_rtc is able to use the rate control
 library.
 * Loopfilter level and CDEF filter level is supported by RTC rate control
 library.
 * New speed (--cpu-used) 11, intended for RTC screen sharing, added for
 faster encoding with ~3% bdrate loss with 16% IC (instruction count)
 speedup compared to speed 10.

 - Compression Efficiency Improvements

 * Improved VoD encoding performance

 * 0.1-0.6% BDrate gains for encoding speeds 2 to 6
 * Rate control accuracy improvement in VBR mode

 * RTC encoding improvements

 * Screen content mode: 10-19% BDrate gains for speeds 6 - 10
 * Temporal layers video mode, for speed 10:

 * 2 temporal layers on low resolutions: 13-15% BDrate gain
 * 3 temporal layers on VGA/HD: 3-4% BDrate gain

 - Perceptual Quality Improvements

 * Fixed multiple block and color artifacts for RTC screen content by

 * Incorporating color into RD cost for IDTX
 * Reducing thresholds for palette mode in non RD mode
 * Allowing more palette mode testing

 * Improved color sensitivity for altref in non-RD mode.
 * Reduced video flickering for temporal layer encoding.

 - Speedup and Memory Optimizations

 * Speed up the VoD encoder

 * 2-5% for encoding speed 2 to 4
 * 9-15% for encoding speed 5 to 6
 * ARM

 * Standard bitdepth

 * speed 5: +31%
 * speed 4: +2%
 * speed 3: +9%
 * speed 2: +157%

 * High bitdepth

 * speed 5: +85%

 * RTC speedups

 * Screen content mode

 * 15% IC speedup for speeds 6-8
 * ARM: 7% for speed 9, 3% for speed 10

 * Temporal layers video mode

 * 7% speedup for 3 temporal layers on VGA/HD, for speed 10

 * Single layer video

 * x86: 2% IC speedup for speeds 7-10
 * ARM: 2-4% speedup across speeds 5-10

 - Bug Fixes

 * aomedia:3261 Assertion failed when encoding av1 with film grain and
 '--monochrome' flag
 * ... [Please see the references for more information on the vulnerabilities]");
