Nah, it just looks like an old archive (those are really changes that were there yesterday or the day before).
I updated it late last night (PST) with the last of the changes, and the current push is just missing most of it (and still has those nasty (De)Compiler comments).
Sometimes it can get a little tough to follow since I still diff to Jon's "official" b19 sources and toss out unnecessary differences, which leads to code changing in strange ways (appearance-wise). But it's not like he or Fred are coming back; I probably shouldn't bother anymore, but what can you do.
EDIT: OK, probably final edits up (23:40). You should probably toss the projectile arrays; I'm not really happy with them being there (nuking the one in EffectFactory is still fine tho because it had no real use). I think the best thing would be to try and extend ProRef to actually do something useful (or a more generic 'IdsRef or this static Bitmap' class), but I don't have the strength. Wouldn't make a difference in BG2 anyhow. There are still some dumb bugs in IWD scripting, but it's not my fault and I don't care anymore, (There might be another bug in the history code, but it's better than it was.)
Not really any good changes this year, I guess, but at least it got some small structure updates for the less worthy IE games.
