+## 1.24.3
+
+- Upgrade to project-loader 4.0.0
+- Backends are now only tested against 2023.2 and above (up from 2022.2) due to a bug in MPS
+  (https://youtrack.jetbrains.com/issue/MPS-39248/Cant-find-property-constraints-errors-for-base-language)
+  which makes newer MPS versions break when opening projects from old MPS versions.
+
 ## 1.24.2
 
 - `execute` now applies the indexing workaround like `modelcheck` and `generate`.
