************ October Release Notes update ******************
Security flaw in FFmpeg 5.1 was discovered and Andrew forwarded the patch for us to use.
A Direct Copy speed-up has been added for EXR and PPM sequences that Andrew found.
Tiny corrections and addition to Cinelerra_factory presets and plugin.opts.
Newer versions of Ubuntu require an additional package install for bld_prepare.sh as Goat found.
The Manual has had another section added, Alternative Views of Overlay Modes, which presents a more “real world” usage display of the overlay modes using a color/black & white gradient + video.
