- [`RangeInclusive` now checks for exhaustion when calling `contains` and indexing.][78109]
- [`ToString::to_string` now no longer shrinks the internal buffer in the default implementation.][77997]
-- [`ops::{Index, IndexMut}` are now implemented for fixed sized arrays of any length.][74989]
Stabilized APIs
---------------
- [Macros that end with a semi-colon are now treated as statements even if they expand to nothing.][78376]
- [Rustc will now check for the validity of some built-in attributes on enum variants.][77015]
Previously such invalid or unused attributes could be ignored.
+- Leading whitespace is stripped more uniformly in documentation comments, which may change behavior. You
+ read [this post about the changes][rustdoc-ws-post] for more details.
+- [Trait bounds are no longer inferred for associated types.][79904]
