Stabilized APIs #

These APIs are now stable in const contexts:

Cargo #

  • Enable -Zdoctest-in-workspace by default. When running each documentation test, the working directory is set to the root directory of the package the test belongs to. docs #12221 #12288
  • Add support of the “default” keyword to reset previously set build.jobs parallelism back to the default. #12222

Compatibility Notes #

  • Alter Display for Ipv6Addr for IPv4-compatible addresses
  • Cargo changed feature name validation check to a hard error. The warning was added in Rust 1.49. These extended characters aren’t allowed on crates.io, so this should only impact users of other registries, or people who don’t publish to a registry. #12291
