Initially this news post, and the changes detailed above, actually related to the release of SourceMod 1.4.5 - 1.4.6 is bug-fix release to fix a critical bug discovered shortly after the release of 1.4.5.
Thanks to the rest of the SM team as well as KyleS for one of the crash fixes and a minor memory leak fix, Powerlord for helping with the TF2 define updates, and PimpinJuice for the IClientListener fix.
