Pietro Albini is a member of the Rust infrastructure, release and crates.io teams, contributing to the project since 2018 both as a volunteer and a contractor. Among other things, Pietro managed the release of multiple Rust versions and is the maintainer of Crater, a tool to test compiler changes across the Rust ecosystem to detect regressions.
A new version of the Rust compiler is released every six weeks, with lots of new features and bug fixes in it. So far the Rust team managed to ship stable releases on schedule with almost no regressions, ensuring everyone can upgrade their toolchain without fear of broken builds. This talk explains how our release process works and the tools we developed to catch regressions before our users do.
