Rustup v1.22.1 Release Notes

Release Date: 2020-07-08 // 5 months ago
  • A regression in proxied behaviour slipped in due to a non-compatible change in url slipping in in 2.1 which caused a misbehaviour in env_proxy. ๐Ÿš€ which was fixed but not released to crates.io until after 1.22.0 was built.

    Fortunately, inejge noticed and provided a fix for us by publishing a new env_proxy and providing us with this fix.

    We apologise for any inconvenience this caused.

    ๐Ÿ”„ Changed

    • โšก๏ธ Update to env_proxy 0.4.1 - #2399
    • ๐Ÿ›  Fixed website copy button and copy space overflow - #2398

    Thanks

Previous changes from v1.22.0

  • โ™ป๏ธ Alongside a significant amount of internal refactoring and code updates, ๐Ÿš€ the highlights of this release include:

    • ๐Ÿš€ We have switched to Github Actions to make our CI and release process more consistent.
    • We've invested time in the flow when you reinstall rustup atop an existing installation.
    • We've doubled down on discouraging the use of the internal-development-focussed complete profile. Please use default or minimal unless you're trying to test/develop the Rust tooling itself.
    • We've made a number of subtle quality-of-life improvements around the CLI.
    • โž• Added a (provisionally unofficial) snap of rustup
    • We've worked hard to improve a lot of the messages (error and informational) in the tool.
    • We've increased internal timeouts and retries in an attempt to improve the situation for McAfee users.
    • While it's not a change, we've documented that rust-toolchain must be UTF8 encoded.

    While the changes spanned around 90 individual pull requests, here are the main changes and additionsโ€ฆ

    ๐Ÿ”„ Changed

    • Increased width of copy box on rustup website - #2208
    • When updating a toolchain, indicate the version you updated from as well. - #2152

    โž• Added

    • It is now possible to install rustup even when there's an existing rustup.sh installation, and we can install alongside rustc or cargo without necessarily forcing via -y by means of the RUSTUP_INIT_SKIP_EXISTENCE_CHECKS environment variable. - #2214
