+[8662ab42...rust-1.50.0](https://github.com/rust-lang/cargo/compare/8662ab42...rust-1.50.0)
 
 ### Added
 - Added the `doc` field to `cargo metadata`, which indicates if a target is
   documented.
   [#8869](https://github.com/rust-lang/cargo/pull/8869)
+- Added `RUSTC_WORKSPACE_WRAPPER`, an alternate RUSTC wrapper that only runs
+  for the local workspace packages, and caches its artifacts independently of
+  non-wrapped builds.
+  [#8976](https://github.com/rust-lang/cargo/pull/8976)
+- Added `--workspace` to `cargo update` to update only the workspace members,
+  and not their dependencies. This is particularly useful if you update the
+  version in `Cargo.toml` and want to update `Cargo.lock` without running any
+  other commands.
+  [#8725](https://github.com/rust-lang/cargo/pull/8725)
 
 ### Changed
 - `.crate` files uploaded to a registry are now built with reproducible
   settings, so that the same `.crate` file created on different machines
   should be identical.
   [#8864](https://github.com/rust-lang/cargo/pull/8864)
+- Git dependencies that specify more than one of `branch`, `tag`, or `rev` are
+  now rejected.
+  [#8984](https://github.com/rust-lang/cargo/pull/8984)
+- The `rerun-if-changed` build script directive can now point to a directory,
+  in which case Cargo will check if any file in that directory changes.
+  [#8973](https://github.com/rust-lang/cargo/pull/8973)
+- Slightly optimize `cargo vendor`
+  [#8937](https://github.com/rust-lang/cargo/pull/8937)
+- If Cargo cannot determine the username or email address, `cargo new` will no
+  longer fail, and instead create an empty authors list.
+  [#8912](https://github.com/rust-lang/cargo/pull/8912)
+- Add period to allowed feature name characters.
+  [#8932](https://github.com/rust-lang/cargo/pull/8932)
+- The progress bar width has been reduced to provide more room to display the
+  crates currently being built.
+  [#8892](https://github.com/rust-lang/cargo/pull/8892)
+- `cargo new` will now support `includeIf` directives in `.gitconfig` to match
+  the correct directory when determining the username and email address.
+  [#8886](https://github.com/rust-lang/cargo/pull/8886)
 
 ### Fixed
+- Fixed `cargo metadata` and `cargo tree` to only download packages for the
+  requested target.
+  [#8987](https://github.com/rust-lang/cargo/pull/8987)
+- Updated libgit2, which brings in many fixes, particularly fixing a zlib
+  error that occasionally appeared on 32-bit systems.
+  [#8998](https://github.com/rust-lang/cargo/pull/8998)
+- Fixed stack overflow with a circular dev-dependency that uses the `links`
+  field.
+  [#8969](https://github.com/rust-lang/cargo/pull/8969)
+- Fixed `cargo publish` failing on some filesystems, particularly 9p on WSL2.
+  [#8950](https://github.com/rust-lang/cargo/pull/8950)
 
 ### Nightly only
 - Allow `resolver="1"` to specify the original feature resolution behavior.
