| ### Compose compiler |
| |
| #### New features |
| - [`c1bbb47`](https://github.com/JetBrains/kotlin/commit/c1bbb479ed4d37b19407917bb7c3bad14f99406c) Started inferring the stability of all interfaces to be |
| `Stability.Unknown`, expect for those explicitly marked as known |
| stable. |
| |
| #### Fixes |
| - [`b/511102714`](https://issuetracker.google.com/issues/511102714) Made the default stability of non-final classes `Unknown` |
| instead of `Stable` |
| - [`b/509945632`](https://issuetracker.google.com/issues/509945632) Do not generate groups in inline lambdas without `@Composable` calls. |
| - [`b/504284805`](https://issuetracker.google.com/issues/504284805) Fix indentation for generated proguard mappings. |
| - [`b/422193018`](https://issuetracker.google.com/issues/422193018) Fix applier inference for nested composables of different types. |
| - [`b/497751457`](https://issuetracker.google.com/issues/497751457) Prevent a `$stable` property from being added to any object. |
| - [`b/427530633`](https://issuetracker.google.com/issues/427530633) Do not infer a getter call as static across when it is defined in another file. |
| - [`b/427530633`](https://issuetracker.google.com/issues/427530633) Started using `Stability.Runtime` more broadly. Now, when an |
| element depends on the stability of an `internal` or `public` class |
| defined in another file, the element will no longer infer the |
| stability of that class and will depend on the runtime stability of |
| that class instead. |
