Commit: 38fb8f9
Release: 2026-04-06 (v0.3.2854)
Universal VSIX
This release adds a platform-independent VSIX that VS Code will install on platforms where rust-analyzer doesn't offer binaries.
On supported platforms, the extension should keep working as before, but a Code bug might cause it to fail to activate.
If that happens, you should uninstall and reintall the rust-analyzer extension.

#21928(first contribution) support macro expansion in#[doc = ...]attributes.#19956implement#[feature(more_qualified_paths)].#21322add option to put type hints at the end of the line.#19659add support for folding ranges in chained expressions.#21516publish universal VSIX without a built-in server binary, for unsupported platforms.
