+## New Features
+
+* [#8755] Support [`let_chains`](https://rust-lang.github.io/rfcs/2497-if-let-chains.html) (by [@Kobzol])
+
+* [#9105] Allow to run a specific [documentation test](https://doc.rust-lang.org/rustdoc/write-documentation/documentation-tests.html) [all the ways](https://plugins.jetbrains.com/plugin/8182-rust/docs/rust-testing.html) you can run a usual test (by [@Kobzol])
+
+  {% include gif-img.html path="/assets/posts/changelog-182/run_doctest" w="700px" %}
+
+* [#9349] Decorate MSVC type names when rendering values in the debugger on Windows. Now the Rust type names containing MSVC-specific wrappers are rendered properly, e.g. `tuple$<Foo, ref$<Bar>>` is replaced by `(Foo, &Bar)`.
+  This feature can be disabled via the `Decorate MSVC type names` checkbox in the `File | Settings | Build, Execution, Deployment | Debugger | Data Views | Rust` settings

+
+* [#7134] Add a quick-fix to generate missing trait member definitions in trait implementations (by [@Sejsel])
+
+  {% include gif-img.html path="/assets/posts/changelog-182/add_definition_to_trait" w="700px" %}
+
+* Procedural macro support improvements:
+  * [#9615] Split `org.rust.macros.proc` experimental feature into sub-features:
+    - `org.rust.macros.proc.function-like` enables [function-like] procedural macros expansion
+    - `org.rust.macros.proc.derive` enables [derive] procedural macro expansion
+    - `org.rust.macros.proc.attr` enables [attribute] procedural macro expansion
+    - `org.rust.macros.proc` enables all the above
+
+    It should help us to enable macro support gradually.
+
+    Note, since the procedural macro support is still experimental, these features are disabled by default. You can turn them on via `Help | Find Action | Experimental Features` dialog
+
+  * [#9628] Enable the expansion of [function-like] procedural macros in the [nightly builds].
+    For more information, check the [implementation PR](https://github.com/intellij-rust/intellij-rust/pull/6564) and the corresponding [tracking issue](https://github.com/intellij-rust/intellij-rust/issues/6908).
+
+  * [#9614] Fix the expansion of [attribute] and [derive] procedural macros inside functions
+
+  * [#9559] Fix duplicate completion for already imported [attribute] procedural macros
+
+  * [#9526] Insert brackets of the proper form (`()`, `[]` or `{}`, depending on the macro's documentation) when completing procedural macro calls
+
+* [#9650] Increase the minimal supported version of Rust to 1.56
+
+* [#8916] Fix emulating terminal in output console in some cases
+
+## Fixes
+
+* Type inference fixes:
+  * [#9598], [#9639] Fix false-positive `trait bound is not satisfied E0277` annotations.
+    Infer types properly when there are trait bounds on the `Self` type
+
+  * [#9552] Properly infer type of custom macros that shadow built-in macros
+
+  * [#7450] Properly infer array size when it refers to a constant (by [@Kobzol])
+
+  * [#9586] Infer const arguments in struct literal paths
+
+  * [#9620] Normalize associated type in `impl` item trait reference
+
+  * [#9631] Fix type inference in the case of normalizable associated type projections like `<A as B>::C`
+
+* [#9637] Fix [build script] evaluation failure when the native helper binary was not found
+
+* [#9627] Do not show line markers for tests in dependence crates
+
+* [#9562] Fix `Create module file` quick-fix in 2022.3 EAPs
+
+* [#9556] Temporary disable `Insert imports on paste` feature because it may be slow when copying large code fragments.
+  The corresponding option is located in `Preferences | Editor | General | Auto Import | Rust` settings
+
+* [#9550] Do not resolve and complete macros after `::` when Rust edition 2018 or later is used
+
+* [#9469] Fix randomly appearing false-positive `Variable is never used` annotation when the variable is only used in a macro call
+
+* [#9170] Fix completion for raw identifiers inside `use` declarations (by [@Stzx])
