+- Update to release 4.0.0
+  * Extended the CRF range to 70, reducing the impact or QP scaling
+    allowing the encoder to reach lower bitrates.
+  * Added quarter steps between CRF increments to allow for further
+    granularity in QP selection.
+  * Added ability to calculate per-frame PSNR and SSIM metrics.
+  * Added tune IQ and MS-SSIM for Still Image coding mode.
+  * ~5-8x speedup M11-M0 at the same quality levels with tune
+    MS-SSIM, and ~5-8% BD-Rate improvements at the same complexity
+    with tune MS-SSIM.
+  * ~5-15% speedup at similar quality levels in `--rtc` mode across
+    presets 7–11.
+  * Tradeoff improvements for the Random Access mode (VOD use case)
+    showing a 10–25% speedup across presets M7 down to M0 for
+    `--fast-decode 1` and 2.
+  * Added AC Bias, a psychovisual feature that improves detail
+    preservation and film grain retention.
+  * Update S-Frame support to allow setting it in a specific decode
+    order option and with more QP options.
