+  documented.
+  [#8869](https://github.com/rust-lang/cargo/pull/8869)
+
+### 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)
+

 ## Cargo 1.49 (2020-12-31)
-[75615f8e...HEAD](https://github.com/rust-lang/cargo/compare/75615f8e...HEAD)
+[75615f8e...rust-1.49.0](https://github.com/rust-lang/cargo/compare/75615f8e...rust-1.49.0)
 
 ### Added
 - Added `homepage` and `documentation` fields to `cargo metadata`.
   [#8744](https://github.com/rust-lang/cargo/pull/8744)
+- Added the `CARGO_PRIMARY_PACKAGE` environment variable which is set when
+  running `rustc` if the package is one of the "root" packages selected on the
+  command line.
+  [#8758](https://github.com/rust-lang/cargo/pull/8758)
+- Added support for Unix-style glob patterns for package and target selection
+  flags on the command-line (such as `-p 'serde*'` or `--test '*'`).
+  [#8752](https://github.com/rust-lang/cargo/pull/8752)
 
 ### Changed
 - Computed LTO flags are now included in the filename metadata hash so that
   changes in LTO settings will independently cache build artifacts instead of
   overwriting previous ones. This prevents rebuilds in some situations such as
   switching between `cargo build` and `cargo test` in some circumstances.
   [#8755](https://github.com/rust-lang/cargo/pull/8755)
+- `cargo tree` now displays `(proc-macro)` next to proc-macro packages.
+  [#8765](https://github.com/rust-lang/cargo/pull/8765)
+- Added a warning that the allowed characters for a feature name have been
+  restricted to letters, digits, `_`, `-`, and `+` to accommodate future
+  syntax changes. This is still a superset of the allowed syntax on crates.io,
+  which requires ASCII. This is intended to be changed to an error in the
+  future.
+  [#8814](https://github.com/rust-lang/cargo/pull/8814)
+- `-p` without a value will now print a list of workspace package names.
+  [#8808](https://github.com/rust-lang/cargo/pull/8808)
 
 ### Fixed
 - Fixed building a library with both "dylib" and "rlib" crate types with LTO enabled.
   [#8754](https://github.com/rust-lang/cargo/pull/8754)
+- Fixed paths in Cargo's dep-info files.
+  [#8819](https://github.com/rust-lang/cargo/pull/8819)
+- Fixed inconsistent source IDs in `cargo metadata` for git dependencies that
+  explicitly specify `branch="master"`.
+  [#8824](https://github.com/rust-lang/cargo/pull/8824)
+- Fixed re-extracting dependencies which contained a `.cargo-ok` file.
+  [#8835](https://github.com/rust-lang/cargo/pull/8835)
 
 ### Nightly only
-
+- Fixed a panic with `cargo doc -Zfeatures=itarget` in some situations.
+  [#8777](https://github.com/rust-lang/cargo/pull/8777)
+- New implementation for namespaced features, using the syntax `dep:serde`.
+  [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#namespaced-features)
+  [#8799](https://github.com/rust-lang/cargo/pull/8799)
+- Added support for "weak" dependency features, using the syntax
+  `dep_name?/feat_name`, which will enable a feature for a dependency without
+  also enabling the dependency.
+  [#8818](https://github.com/rust-lang/cargo/pull/8818)
+- Fixed the new feature resolver downloading extra dependencies that weren't
+  strictly necessary.
+  [#8823](https://github.com/rust-lang/cargo/pull/8823)
+- Vendored builds now work with `-Zbuild-std`.
+  [#8834](https://github.com/rust-lang/cargo/pull/8834)
