Release 2.5.19.1 (Sep 15 2025) -- compared to 2.5.19.0
- ffmpeg: Replace deprecated and soon removed avcodec_close with avcodec_free_context #4837 (by Vlad Erium)
- heic: Use get_plane2 introduced by libheif 1.20.2 #4851 (by toge)
- ci: Various fixes to repair CI that had rusted away in the last few
months due to changes on the runners or to dependencies.
Note that this is a patch release for the obsolete 2.5 branch that merely repairs its ability to build under new versions of some dependencies. You need not upgrade if you are not encountering build problems. Except for legacy constraints, everybody should currently be using OIIO 3.0 and testing the beta for 3.1 which will become the new supported branch very soon.
