Tacoma offline installers have been updated to v2019-12-20. The relevant message from Steam (dated Dec 19, 2019):

Hi there! If you already own Tacoma, you may notice a large patch from Steam today. But, despite the patch size, it should keep everything pretty much exactly as it was: we've updated the game to be compliant with MacOS Catalina's new security requirements, which required upgrading the game to a new version of Unity-- which means practically every file got touched in the process, causing a large patch size on Steam. But, everything should work the same, just maybe running a little smoother, with a few bugs fixed that we found along the way, and better compatibility for Xbox and DualShock controllers.
