+## New Features
+
+* [#9532] Enable [build script] evaluation by default.
+  Now the plugin builds and executes all build scripts in the project (including build scripts in external dependencies)
+  during project model loading to create source code generated during compilation and collect information about
+  generated environment variables and `cfg` options. A typical use case is to generate some code by a build script
+  and include it via `include!(concat!(env!("OUT_DIR"), "/path_to_generated_file.rs"))`. Now the plugin understands
+  where generated sources are located and includes them into its own analysis.
+  Under the hood, build script evaluation uses `cargo check` call modified in a way to compile and execute only
+  host code (i.e. only build scripts and procedural macros as well as their dependencies). Besides execution of
+  build scripts code, it also allows the plugin to compile all procedural macro libraries which is required
+  for procedural macro expansion.
+  Note, procedural macro expansion is still disabled by default. To turn it on, enable `org.rust.macros.proc`
+  [experimental] feature.
+
+  Read more about build scripts and how to work with them in Rust plugin in the corresponding
+  [blog post](https://blog.jetbrains.com/rust/2022/10/24/evaluating-build-scripts-in-the-intellij-rust-plugin/)
+
+* [#9239] Support new Cargo features syntax from Rust 1.60.0. See [Rust release blog post] for more info about the
+  syntax
+
+* [#9429] Add `Inline type alias` refactoring in addition to existing `Substitute type alias` intention
+
+  {% include gif-img.html path="/assets/posts/changelog-181/inline" w="600px" %}
+
+* [#9517] Provide code folding for `extern` blocks (`extern "C" { ... }`) (by [@Kobzol])
+
+* [#9459] Resolve and complete items from the stdlib in Rust files which don't belong to a particular Cargo project (detached and [scratch](https://www.jetbrains.com/help/idea/scratches.html) files)
+
+* [#9451] Provide completion for `'static` lifetime (by [@Kobzol])
+
+* [#9443] Add imports for macros by [`Move refactoring`].
+  Currently, only macros from dependency crates are supported
+
+* [#9433] Take into account return type of some stdlib macros in completion sorting.
+  For example, now `vec![]` will be bubbled up in the completion list if expected expression type is `Vec`
+
+* [#9502] Annotate usage of `wasm` [external ABI] as experimental
+
+## Performance Improvements
+
+* [#9488] Fix IDE freezing on searching implementation via `Has Implementation` line marker in gutter
+
+* [#9357] Slightly speed up name resolution
+
+## Fixes
+
+* [#9567] Fix possible stack overflow during type inference
+
+* [#9545] Fix name resolution of absolute path when there is `extern crate` with alias
+
+* [#9537] Fix `Attach file to module` quick-fix. Now `File is not included in module tree` bar will disappear after
+  attaching the file to a module tree as expected
+
+* [#9510] Don't use private re-exports declared in the same crate by `Import` quick-fix
+
+* [#9507] Improve error message for [`E0407`] error
+
+* [#9506] Don't reorder re-exports of legacy macros when optimizing imports
+
+* [#9504] Add imports for return type by [`Change signature`] refactoring properly
+
+* [#9485] Handle [`$crate`] variable during procedural macro expansion properly
+
+* [#9430] Fix inference of types with mixed type/const type arguments
+
+* [#9416] Fix false-positive [E0117] in some cases
+
+* [#9374] Fix nested loop/block labels shadowing
+
+* [#9358] Fix `todo!()` macro type inference
+
+* [#9312], [#9558] Filter out attribute and derive procedural macros in usual macro calls completion
+
+* [#9540] Fix procedural macro expansion cache invalidation. See issue [#9539] for more details
+
+## Internal Improvements
+
+* [#9480] Keep info about compiler features in json instead of generated Kotlin code
