+2021-09-27 v1.11.0 "Smew Duck"
+ This maintenance release adds support for VBR mode in VP9 rate control
+ interface, new codec controls to get quantization parameters and loop filter
+ levels, and includes several improvements to NEON and numerous bug fixes.
+
+ - Upgrading:
+ New codec control is added to get quantization parameters and loop filter
+ levels.
+
+ VBR mode is supported in VP9 rate control library.
+
+ - Enhancement:
+ Numerous improvements for Neon optimizations.
+ Code clean-up and refactoring.
+ Calculation of rd multiplier is changed with BDRATE gains.
+
+ - Bug fixes:
+ Fix to overflow on duration.
+ Fix to several instances of -Wunused-but-set-variable.
+ Fix to avoid chroma resampling for 420mpeg2 input.
+ Fix to overflow in calc_iframe_target_size.
+ Fix to disallow skipping transform and quantization.
+ Fix some -Wsign-compare warnings in simple_encode.
+ Fix input file path in simple_encode_test.
+ Fix valid range for under/over_shoot pct.
+
+2021-03-09 v1.10.0 "Ruddy Duck"
+ This maintenance release adds support for darwin20 and new codec controls, as
+ well as numerous bug fixes.
+
+ - Upgrading:
+ New codec control is added to disable loopfilter for VP9.
+
+ New encoder control is added to disable feature to increase Q on overshoot
+ detection for CBR.
+
+ Configure support for darwin20 is added.
+
+ New codec control is added for VP9 rate control. The control ID of this
+ interface is VP9E_SET_EXTERNAL_RATE_CONTROL. To make VP9 use a customized
+ external rate control model, users will have to implement each callback
+ function in vpx_rc_funcs_t and register them using libvpx API
+ vpx_codec_control_() with the control ID.
+
+ - Enhancement:
+ Use -std=gnu++11 instead of -std=c++11 for c++ files.
+
+ - Bug fixes:
+ Override assembler with --as option of configure for MSVS.
+ Fix several compilation issues with gcc 4.8.5.
+ Fix to resetting rate control for temporal layers.
+ Fix to the rate control stats of SVC example encoder when number of spatial
+ layers is 1.
+ Fix to reusing motion vectors from the base spatial layer in SVC.
+ 2 pass related flags removed from SVC example encoder.
+
+2020-07-29 v1.9.0 "Quacking Duck"
+ This release adds support for NV12, a separate library for rate control, as
+ well as incremental improvements.
+
+ - Upgrading:
+ NV12 support is added to this release.
+ A new interface is added for VP9 rate control. The new library libvp9rc.a
+ must be linked by applications.
+ Googletest is updated to v1.10.0.
+ simple_encode.cc is compiled into a new library libsimple_encode.a with
+ CONFIG_RATE_CTRL.
+
+ - Enhancement:
+ Various changes to improve VP9 SVC, rate control, quality and speed to real
+ time encoding.
+
+ - Bug fixes:
+ Fix key frame update refresh simulcast flexible svc.
+ Fix to disable_16x16part speed feature for real time encoding.
+ Fix some signed integer overflows for VP9 rate control.
+ Fix initialization of delta_q_uv.
+ Fix condition in regulate_q for cyclic refresh.
+ Various fixes to dynamic resizing for VP9 SVC.
+
+2019-12-09 v1.8.2 "Pekin Duck"
+ This release collects incremental improvements to many aspects of the library.
+
+ - Upgrading:
+ ARCH_* defines have been removed in favor of VPX_ARCH_*.
+
2019-07-15 v1.8.1 "Orpington Duck"
This release collects incremental improvements to many aspects of the library.
of particular interest to real time streaming applications.
Temporal scalability allows the encoder to produce a stream that can
