+Release: release:2025-03-17[] (`v0.3.2345`)
+
+== Announcement
+
+This release brings two major changes, which might make it slightly _spicier_ than usual.
+
+The first is upgrading to the latest version of `salsa`, the incremental evaluation framework used by rust-analyzer.
+This will make it possible to implement parallel evaluation and persistency in the future.
+
+The second change is to use `salsa` for the crate graph, making it incremental.
+Adding or removing a dependency, or editing a build script or proc macro, will now invalidate only the affected crates instead of the entire workspace.
+
+== New Features
