Rustup v1.24.3 Release Notes

Release Date: 2021-05-31 // almost 3 years ago
  • πŸš€ This patch release focusses around resolving some regressions in behaviour in πŸš€ the 1.24.x series. One problem, related to accounting for the release of data πŸ›  blocks in the unpack slab allocator, fixed in pr#2779, would manifest in the πŸ›  installer hanging during installation. A second, fixed in pr#2781, manifested in very early Rust versions (1.0 through 1.7) repeatedly having their checksums fetched despite already being installed. ⚠ Finally the heuristic which started warning that toolchains being installed may not work on the given host was improved in pr#2782 to reduce false-positive 🏁 rate and reduce worry among Windows users in particular.

    βž• Added

    • βž• Added the ability to configure the auto-self-update functionality. This will be of most use when people are testing unreleased versions of Rustup and wish to ensure they don't accidentally lose the test version, without having to remember to run with --no-self-update all the time. pr#2763

    πŸ”„ Changed

    • We no longer delete the top level of $RUSTUP_HOME/tmp and $RUSTUP_HOME/download meaning that if you have these set up as symlinks to another place, or bind mounts, etc. things should work. pr#2433
    • We more gracefully handle outlier situations with unpack-RAM, panicing less often, clamping settings into viable ranges and warning instead. pr#2780
