1Rust 2==== 3 4Rust Update Policy 5------------------ 6 7Given that for some distributions it's not feasible to keep up with the 8pace of Rust, we promise to only bump the minimum required Rust version 9following those rules: 10 11- Only up to the Rust requirement of other major Linux desktop 12 components, e.g.: 13 14 - `Firefox ESR <https://whattrainisitnow.com/release/?version=esr>`__: 15 `Minimum Supported Rust Version: 16 <https://firefox-source-docs.mozilla.org/writing-rust-code/update-policy.html#schedule>`__ 17 18 - latest `Linux Kernel Rust requirement 19 <https://docs.kernel.org/process/changes.html#current-minimal-requirements>`__ 20 21- Only require a newer Rust version than stated by other rules if and only 22 if it's required to get around a bug inside rustc. 23 24As bug fixes might run into rustc compiler bugs, a rust version bump _can_ 25happen on a stable branch as well. 26
