This one is especially for server owners as 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.

1.6.2: - Orange box version

• 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: - Original Source version

• 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)
