Plone

Plone is a content management system that is built on the powerful Zope application server. The project experienced many delays with its 2.1 release. This made it difficult for Plone consultants to choose whether to use the old release or wait for the new one, and users faced many upgrade issues when 2.1 was finally released and had many changes. Partly to address these problems and partly in order to sync their releases with Zope, they decided in 2005 to move to a six month time based release cycle.

OpenOffice.org

OpenOffice.org is an office suite offering various integrated applications, such as a word processor and a spreadsheet. Originally developed by StarDivision, StarOffice was acquired by Sun who released it as free software as OpenOffice.org in July 2000. While Sun still maintains fairly tight control over the development of OpenOffice.org, many other vendors, in particular Novell, are important contributors to the project. The project had a fairly long release cycle of about 18 months to accommodate StarOffice, the commercial product from Sun. There were many delays, making it hard for vendors to decide which version to include. OpenOffice.org moved to a three month release cycle after their long-delayed 2.0 release, published 26 months after 1.1. The new release cycle is viewed as a positive development by contributors who get their features and fixes out to users faster. Nevertheless, at the end of 2006 a discussion took place in which a six month interval was suggested. Apparently users didn't want new features every three months and the short interval between releases put a lot of pressure on the QA team.
