+* Fix IntelliSense crashes involving precompiled headers, `constexpr` evaluation, C++20 `requires` expressions, SFINAE, and incomplete nested class declarations.
+* Fix false IntelliSense errors for nested C++20 `requires` expressions and fold-expression constraints in MSVC module templates.
+* Fix stale IntelliSense diagnostics and inconsistent document snapshots during concurrent edits and requests.
+* Fix tag parsing of user-defined literal operator suffixes when macro expansion is involved.
+* Fix completion for declarations imported from standard-library modules when using MSVC.
+* Fix 'Create Declaration/Definition' matching for functions in the global namespace.
