+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.
