+Compatibility Notes
+-------------------
+
+- [Refactor weak symbols in std::sys::unix][90846]
+  This may add new, versioned, symbols when building with a newer glibc, as the
+  standard library uses weak linkage rather than dynamically attempting to load
+  certain symbols at runtime.
+- [Deprecate crate_type and crate_name nested inside `#![cfg_attr]`][83744]
+  This adds a future compatibility lint to supporting the use of cfg_attr
+  wrapping either crate_type or crate_name specification within Rust files;
+  it is recommended that users migrate to setting the equivalent command line
+  flags.
+- [Remove effect of `#[no_link]` attribute on name resolution][92034]
+  This may expose new names, leading to conflicts with preexisting names in a
+  given namespace and a compilation failure.
+- [Cargo will document libraries before binaries.][cargo/10172]
+- [Respect doc=false in dependencies, not just the root crate][cargo/10201]
+- [Weaken guarantee around advancing underlying iterators in zip][83791]
+- [Make split_inclusive() on an empty slice yield an empty output][89825]
+- [Update std::env::temp_dir to use GetTempPath2 on Windows when available.][89999]
+
+Internal Changes
+----------------
+
+These changes provide no direct user facing benefits, but represent significant
+improvements to the internals and overall performance of rustc
+and related tools.
+
+- [Fix many cases of normalization-related ICEs][91255]
+- [Replace dominators algorithm with simple Lengauer-Tarjan][85013]
+- [Store liveness in interval sets for region inference][90637]
+
+- [Remove `in_band_lifetimes` from the compiler and standard library, in preparation for removing this
+  unstable feature.][91867]
