Metamod:Source versions 1.6.2 and 1.4.4 have been released. These are small bug-fix releases.

The 1.6.2 fixes a potential compatibility bug with an upcoming Orange Box SDK update. We would like to thank "omega" at Valve for notifying and verifying this for us ahead of time.

1.6.2:

 - Fixed a bug where VDF files were opened by MM:S even if the .vdf extension was 
   not at the very end of the filename. For example, "plugin.vdf.disabled" would have 
   been opened in previous versions.  (bug 1534)
 - Removed FCVAR_REPLICATED from MM:S convars. The following message will no 
   longer appear in client consoles: ConVarRef metamod_version doesn't point to an 
   existing ConVar. (bug 1480)
 - Fixed a compatibility bug against future IServerPluginCallbacks API versions.

1.4.4:

 - Fixed a bug where loading plugins built for MM:S 1.3 or older (API ver <= 9)
   would cause a crash.
 - Fixed a bug where loading plugins using VDF files caused Metamod:Source
   to crash on The Ship. (bug 1523)
 - Fixed a class of crashes caused by improper cvar removal handling. (bug 1416)
 - Fixed a bug where VDF files were opened by MM:S even if the .vdf extension was 
   not at the very end of the filename. For example, "plugin.vdf.disabled" would have 
   been opened in previous versions. (bug 1534)
 - Removed FCVAR_REPLICATED from MM:S convars. (bug 1479)

Special thanks goes to Damaged Soul for fixing the notorious ConVar removal crashing bugs in the 1.4 branch.

Metamod:Source 1.6.1 has been released. It is a small bug-fix release to fix an incompatibility issue with an upcoming Orange Box update. I would like to thank Valve for notifying us about this problem so we could fix it in advance.
