+Release: release:2025-08-11[] (`v0.3.2571`)
+
+== An Update on the Next Trait Solver
+
+We are very close to switching from `chalk` to the next trait solver, which will be shared with `rustc`.
+`chalk` is _de-facto_ unmaintained, and sharing the code with the compiler will greatly improve trait solving accuracy and fix long-standing issues in `rust-analyzer`.
+This will also let us enable more on-the-fly diagnostics (currently marked as experimental), and even significantly improve performance.
+
+However, in order to avoid regressions, we will suspend the weekly releases until the new solver is stabilized.
+In the meanwhile, please test the pre-release versions (nightlies) and report any issues or improvements you might notice.
+
+== Fixes
+
+* pr:20381[] check expected type for assignments in completions.
