v2.15.0 Preview 2

Added 2025-08-27 03:51:30 +0000 UTC

Howdy patrons! We’ve just shipped v2.15.0-pre.2 - a release focused mainly on bug fixes and polish as we prepare for the big public launch. While this one is mostly about tightening bolts and squashing bugs, we couldn’t resist adding some shiny new things: the AI Toolkit package, a Manual Install button for extensions, Next/Previous navigation on Civitai results, Negative Rejection Steering (NRS) by @reithan in Inference, and a full Czech translation courtesy of @PEKArt.

Looking ahead, we want your input for v2.16! 💡 We’ll be putting up a poll soon, but please drop your ideas in the comments - we’ll gather them up and add them to the poll so everyone can vote. Your feedback directly shapes what comes next, so don’t be shy!
