The assembly version does not have any important meaning, not for assemblies used in this manner. It would only matter if you were to reference other assemblies across files, which is not done for these application settings - and even then the only real importance would be to increment it when its changed in an incompatible manner, not necessarily linked to the application version, which is stored in a resource file instead of the assembly. - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
