Scott Long: [FreeBSD-Announce] FreeBSD Status Report July-December 2004. 2005-01-07. [dostęp 2023-03-13]. Cytat: „For the 6-CURRENT development branch as well as all future development and stable branches, we are planning to move to a schedule with fixed timelines that move away from the uncertainty and wild schedule fluctuations of the previous 5.x releases. This means that major branches will happen at 18 month intervals, and releases from those branches will happen at 4 month intervals. There will also be a dedicated period of testing and bug fixing at the beginning of each branch before the first release is cut from that branch. With the shorter and more defined release schedules, we hope to lessen the problem of needed features not reaching users in a reasonable time, as happened too often with 5.x. This is a significant change in our strategy, and we look forward to realizing the benefits of it. This will kick off with the RELENG_6 branch happing in June of 2005, followed by the 6.0 release in August of 2005. (ang.).
