Haiku R1/beta6 was released on August 26, 2026, about two years after the previous beta and a week after the project celebrated its 25th anniversary. Haiku is an open-source operating system inspired by the BeOS system of the 1990s, developed by a community of volunteers. The release includes updates described in the project's release notes and offers users the option to download the new version or upgrade existing installations. The Haiku development team continues to maintain the operating system, and users are encouraged to test the beta and report any issues.
