 API changes, most recent first:
 
+2022-08-xx - xxxxxxxxxx - lavu 57.34.100 - pixfmt.h
+  Add AV_PIX_FMT_RGBX64 and AV_PIX_FMT_BGRX64 pixel formats.
+
 2022-08-19 - 352799dca8 - lavc 59.42.102 - codec_id.h
   Deprecate AV_CODEC_ID_AYUV and ayuv decoder/encoder. The rawvideo codec
   and vuya pixel format combination will be used instead from now on.
