[`2025-08-11`](https://www.github.com/rust-lang/rust-analyzer/releases/2025-08-11) (`v0.3.2577`) + +## 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 notice, either on
