While the SM snapshots contained up-to-date gamedata since very, very shortly before the update was released, the SM gamedata updater did not initially have this updated data. I had to remember to hit the button on it after the update was released, and I forgot until probably close to an hour later. If anyone is still having an issue with CSWeaponDrop or RoundRespawn not being found, restart your server.
Additionally, the new include/core.inc was missing some MarkNativeAsOptional calls for 7 of the new Pb* natives. If you've updated your plugins to work on both CS:GO and other games, you'll want to recompile against the new version of the file (found in SM 1.5.0-hg3756 or later, any OS) to make sure that they can still load properly on other games without error.
