+
+* [#10530] Support [`return_position_impl_trait_in_trait`] feature
+
+* [#10480] Add completion for `for` keyword after `impl` block
+
+## Fixes
+
+* [#10554] Fix `cargo test` on Rust 1.70.0+ stable if the Test Tool Window is enable.
+           Note: now IDE runs `cargo test` with the `RUSTC_BOOTSTRAP=1` environment variable 1.70.0+ stable.
+           This enables required experimental features but may impact build and test results in rare cases.
+
+* [#10528] Fix expansion of macro 2.0 with multiple patterns (cases)
+
+## Internal Improvements
+
+* [#10514] Initial support for [E0505](https://doc.rust-lang.org/error_codes/E0505.html) using MIR framework
