There's https://wiki.mozilla.org/Rust_Update_Policy_for_Firefox which appears to be reasonably current. This is the general policy, but there can be cases like 1.25 where a regression is deemed important enough to delay upgrading the Rust version used for Mozilla builds or increasing the minimum version requirement. You can search Bugzilla for "builders rust" and "require rust" to find bugs tracking those changes respectively, such as https://bugzilla.mozilla.org/show_bug.cgi?id=1450078 This configuration is in tree, changes are made first in central / nightly and then ride the trains. -- Simon Sapin ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform

The plan is to keep the ESR versions on the Rust version that was required to build them when the ESR branch was created. We've done this for our C/C++ compiler versions and that's worked out just fine. Given Rust's compatibility guarantees, you may be able to build ESR with later Rust releases, but your best bet is using the specific Rust version that we're using.
