+### Added
+
+### Changed
+- 🔥 Cargo now supports git repositories where the default `HEAD` branch is not
+ "master". This also includes a switch to the version 3 `Cargo.lock` format
+ which can handle default branches correctly.

+
+### Fixed
+
+### Nightly only
+- The `strip` profile option now supports `true` and `false` values.

 ## Cargo 1.51 (2021-03-25)
-[75d5d8cf...HEAD](https://github.com/rust-lang/cargo/compare/75d5d8cf...HEAD)
+[75d5d8cf...rust-1.51.0](https://github.com/rust-lang/cargo/compare/75d5d8cf...rust-1.51.0)
 
 ### Added
+- 🔥 Added the `split-debuginfo` profile option.
+ [docs](https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#split-debuginfo)
+ [#9112](https://github.com/rust-lang/cargo/pull/9112)
+- Added the `path` field to `cargo metadata` for the package dependencies list
+ to show the path for "path" dependencies.
+ [#8994](https://github.com/rust-lang/cargo/pull/8994)
+- 🔥 Added a new feature resolver, and new CLI feature flag behavior. See the
+ new [features](https://doc.rust-lang.org/nightly/cargo/reference/features.html#feature-resolver-version-2)
+ and [resolver](https://doc.rust-lang.org/nightly/cargo/reference/resolver.html#feature-resolver-version-2)
+ documentation for the `resolver = "2"` option. See the
+ [CLI](https://doc.rust-lang.org/nightly/cargo/reference/features.html#command-line-feature-options)
+ and [resolver 2 CLI](https://doc.rust-lang.org/nightly/cargo/reference/features.html#resolver-version-2-command-line-flags)
+ options for the new CLI behavior. And, finally, see
+ [RFC 2957](https://github.com/rust-lang/rfcs/blob/master/text/2957-cargo-features2.md)
+ for a detailed look at what has changed.
+ [#8997](https://github.com/rust-lang/cargo/pull/8997)
 
 ### Changed
+- `cargo install --locked` now emits a warning if `Cargo.lock` is not found.
+ [#9108](https://github.com/rust-lang/cargo/pull/9108)
+- Unknown or ambiguous package IDs passed on the command-line now display
+ suggestions for the correct package ID.
+ [#9095](https://github.com/rust-lang/cargo/pull/9095)
+- Slightly optimize `cargo vendor`
+ [#8937](https://github.com/rust-lang/cargo/pull/8937)
+ [#9131](https://github.com/rust-lang/cargo/pull/9131)
+ [#9132](https://github.com/rust-lang/cargo/pull/9132)
 
 ### Fixed
+- Fixed environment variables and cfg settings emitted by a build script that
+ are set for `cargo test` and `cargo run` when the build script runs multiple
+ times during the same build session.
+ [#9122](https://github.com/rust-lang/cargo/pull/9122)
+- Fixed a panic with `cargo doc` and the new feature resolver. This also
+ introduces some heuristics to try to avoid path collisions with `rustdoc` by
+ only documenting one variant of a package if there are multiple (such as
+ multiple versions, or the same package shared for host and target
+ platforms).
+ [#9077](https://github.com/rust-lang/cargo/pull/9077)
+- Fixed a bug in Cargo's cyclic dep graph detection that caused a stack
+ overflow.
+ [#9075](https://github.com/rust-lang/cargo/pull/9075)
+- Fixed build script `links` environment variables (`DEP_*`) not showing up
+ for testing packages in some cases.
+ [#9065](https://github.com/rust-lang/cargo/pull/9065)
+- Fixed features being selected in a nondeterministic way for a specific
+ scenario when building an entire workspace with all targets with a
+ proc-macro in the workspace with `resolver="2"`.
+ [#9059](https://github.com/rust-lang/cargo/pull/9059)
+- Fixed to use `http.proxy` setting in `~/.gitconfig`.
+ [#8986](https://github.com/rust-lang/cargo/pull/8986)
 
 ### Nightly only
+- Removed the `publish-lockfile` unstable feature, it was stabilized without
+ the need for an explicit flag 1.5 years ago.
+ [#9092](https://github.com/rust-lang/cargo/pull/9092)
+- Added better diagnostics, help messages, and documentation for nightly
+ features (such as those passed with the `-Z` flag, or specified with
+ `cargo-features` in `Cargo.toml`).
+ [#9092](https://github.com/rust-lang/cargo/pull/9092)
+- Added support for Rust edition 2021.
+ [#8922](https://github.com/rust-lang/cargo/pull/8922)
+- Added support for the `rust-version` field in project metadata.
+ [#8037](https://github.com/rust-lang/cargo/pull/8037)
