 ## Notable Features :id=notable-features
 
-_0.25.0_ is mainly a maintenance release of QMK Firmware -- as per last few breaking changes cycles, there have been a lot of behind-the-scenes changes, mainly:
-
-* continued migration of configuration into `.json` files
-* addressing technical debt
+May 2024 brings about another heavy maintenance release of QMK. Of the 208 PRs created this breaking changes cycle against the `develop` branch, 173 behind-the-scenes PRs (83%!) were aimed at converting, consolidating, and cleaning up keyboards and their configuration data. Not the most glamorous work, but it means QMK is in a much more manageable spot than what it was 3 months prior. The work steadily continues!
