+# 26.0.0
+
+## Major
+ - Removed the `--extras` and `-qscale:v` cli options.
+ - The `ae-ffmpeg` pypi package is deprecated and will be removed in a future release. Future versions of auto-editor will not ship ffmpeg cli binaries.
+ - The `--my-ffmpeg` and `--ffmpeg-location` cli options are deprecated and can be removed in a future release.
+
+## Features
+ - Remove all uses of ffmpeg-cli for video rendering; improves performance by ~20%
+ * Using `--my-ffmpeg` no longer means that libx264 (and friends) would necessarily be used. Instead, use a GPLv3 build of PyAV.
+
+## Fixes
+ - Never write a "null frame" if the timeline is known to be linear. Fixes #468
+
+**Full Changelog**: https:/WyattBlue/auto-editor/compare/25.3.1...26.0.0
