+Subject: [PATCH] avcodec/libjxldec: build against libjxl 0.9
+
+Git master libjxl changed several function signatures, so this commit
+adds some #ifdefs to handle the new signatures without breaking old
+releases. Do note that old git master development versions of libjxl
+will be broken, but no releases will be.

+Subject: [PATCH] avcodec/libjxl.h: include version.h
+
+This file has been exported since our minimum required version (0.7.0),
+but it wasn't documented. Instead it was transitively included by
+<jxl/decode.h> (but not jxl/encode.h), which ffmpeg relied on.
+
+libjxl broke its API in libjxl/libjxl@66b959239355aef5255 by removing
+the transitive include of version.h, and they do not plan on adding
+it back. Instead they are choosing to leave the API backwards-
+incompatible with downstream callers written for some fairly recent
+versions of their API.
+
+As a result, we include <jxl/version.h> to continue to build against
+more recent versions of libjxl. The version macros removed are also
+present in that file, so we no longer need to redefine them.
