Changelog for Patch 1.3001

S.T.A.L.K.E.R.: LOST ALPHA Patch v1.3001 (2nd of May 2014.) changelog:
The patch is savegame compatible, so You do not have to start new game for this patch, but for maximum experience it's recommended.
If you installed 3rd party / user made fixes and mods for Lost Alpha, it's highly recommended to reinstall the game to have a clean install before you apply the official patch. This is required to avoid conflicts with the 3rd party content. We can not give support for such cases.
