+Compatibility Notes
+-------------------
+- [`rustc` no longer treats the `test` cfg as a well known check-cfg](https://github.com/rust-lang/rust/pull/131729), instead it is up to the build systems and users of `--check-cfg`[^check-cfg] to set it as a well known cfg using `--check-cfg=cfg(test)`.
+  This is done to enable build systems like Cargo to set it conditionally, as not all source files are suitable for unit tests.
+  [Cargo (for now) unconditionally sets the `test` cfg as a well known cfg](https://github.com/rust-lang/cargo/pull/14963).
+[^check-cfg]: https://doc.rust-lang.org/nightly/rustc/check-cfg.html
+- [Disable potentially incorrect type inference if there are trivial and non-trivial where-clauses](https://github.com/rust-lang/rust/pull/132325)
+- `std::env::home_dir()` has been deprecated for years, because it can give surprising results in some Windows configurations if the `HOME` environment variable is set (which is not the normal configuration on Windows). We had previously avoided changing its behavior, out of concern for compatibility with code depending on this non-standard configuration. Given how long this function has been deprecated, we're now fixing its behavior as a bugfix. A subsequent release will remove the deprecation for this function.
+- [Make `core::ffi::c_char` signedness more closely match that of the platform-default `char`](https://github.com/rust-lang/rust/pull/132975)
+  This changed `c_char` from an `i8` to `u8` or vice versa on many Tier 2 and 3
+  targets (mostly Arm and RISC-V embedded targets). The new definition may
+  result in compilation failures but fixes compatibility issues with C.
+  The `libc` crate matches this change as of its 0.2.169 release.
+- [When compiling a nested `macro_rules` macro from an external crate, the content of the inner `macro_rules` is now built with the edition of the external crate, not the local crate.](https://github.com/rust-lang/rust/pull/133274)
+- [Increase `sparcv9-sun-solaris` and `x86_64-pc-solaris` Solaris baseline to 11.4.](https://github.com/rust-lang/rust/pull/133293)
+- [Show `abi_unsupported_vector_types` lint in future breakage reports](https://github.com/rust-lang/rust/pull/133374)
+- [Error if multiple super-trait instantiations of `dyn Trait` need associated types to be specified but only one is provided](https://github.com/rust-lang/rust/pull/133392)
+- [Change `powerpc64-ibm-aix` default `codemodel` to large](https://github.com/rust-lang/rust/pull/133811)
+
+<a id="1.85.0-Internal-Changes"></a>
+
+Internal Changes
+----------------
+
+These changes do not affect any public interfaces of Rust, but they represent
+significant improvements to the performance or internals of rustc and related
+tools.
+
+- [Build `x86_64-unknown-linux-gnu` with LTO for C/C++ code (e.g., `jemalloc`)](https://github.com/rust-lang/rust/pull/134690)
