It appears that the Cataclysm Classic version 11.1.5-20250422-1 works on WoW Classic (add 11507 to .toc). Tested on Classic Era, Season of Discovery, and Anniversary Realms.

Could you please add official support.

I also tested on Mists of Pandaria Beta 5.5.0 and Retail 11.1.7. The only change is to the TOC as shown below:

## Interface: 110105,40402,11507,50500,110107

Thank you, I have just pushed 11.1.5-20250525-1, which adds those versions.
