About Hydrogen
Hydrogen is drum-machine software. Its website is mainly a release news page, listing version announcements from 2018 to Oct 2, 2026, the latest being 1.2.7, a patch release with bug fixes, updated translations, and improved forward compatibility for the upcoming 2.0 release. Each announcement links to a further read-more page.

Some versions are labeled beta, which the source describes as previews of new features rather than stable releases.
