Ubuntu has recently implemented a significant policy change requiring all Ubuntu flavors to release a beta version before they can ship a stable release, with no exceptions allowed. Prior to this, some flavors could miss the beta deadline and still proceed to the final release, as was the case with Ubuntu Kylin during the 26.04 LTS cycle.
According to Canonical’s Oliver Reiche, this new regulation is intended to ensure that every flavor is thoroughly prepared for their official launch. He stated, “To ensure that every flavor is fully prepared for the final release, no flavor will be considered for an official release unless it has successfully submitted a Beta release according to the scheduled timeline.”
This mandatory beta requirement aims to enhance the stability of the final releases, allowing for more uniform testing and feedback. Daily builds can fluctuate and often involve a limited user base, while a beta provides a solid snapshot for broader testing. The differences between beta and final releases are expected to be minor, mainly limited to bug fixes, although there are provisions for late feature additions through Feature Freeze Exceptions.
The change is expected to clarify the development process for flavor maintainers by defining which issues need addressing before a release. However, it raises questions about whether this strict approach might put additional pressure on smaller teams who face challenges in attracting and retaining contributors.
