SourceMod 1.2 is a major update. It is backwards compatible with all known plugins (see notes for details).

TODO List

Game Support

SourceMod 1.2 includes full support for two additional game engines:

Left 4 Dead, a new game released by Valve. Notes:
- nextmap.smx will appear disabled, since it has no use.
Do not use forked servers over one copy of SourceMod.

If you compile plugins (or extensions) with SourceMod 1.2, they cannot be run on SourceMod 1.1, even if they do not use new features.
SourceMod 1.2 cannot be "downgraded" to SourceMod 1.1 unless the extensions folder is cleared. This is because the "bintools" extension is in a new location, and the new version will be loaded over the old after downgrading.
Developers: The "usermessage" API has changed. MsgNotify has been removed entirely, and replaced with MsgPostHook. This change is transparent, and no plugins appeared to have been using the API. If you have a plugin relying on the MsgNotify functionality, your plugin will now receive intercepted calls that are blocked as well. Update your source, recompile, and use the new sent parameter to filter.
