Brightness/contrast node was changing color but did not modify alpha or ensured colors are premultiplied on the output. This was giving artifacts later on unless alpha was manually converted. Compositor is supposed to work in premultiplied alpha (except of some really corner cases) so it makes sense to ensure premultiplied alpha after brightness/contrast node. This is now done as an option enabled by default, so we: (a) Keep compatibility with old files. (b) Have correct behavior for newly created files. Later on we can get rid of this option.
