The release branch (https://svn.boost.org/svn/boost/branches/release) is open for merging all stable changes from trunk, including bug fixes and major upgrades to existing libraries. Breaking changes should be coordinated via the mailing list with the developers of the other libraries affected. New libraries may be added, but require permission of a release manager. In other words, except for new libraries, merging changes *does not* need permission from a release manager. I.e. just do it! The release schedule is more aggressive than usual on the front end so that we can maintain our quarterly release schedule: * September 13, 2009: branches/release closed for new libraries and breaking changes to existing libraries. Still open for bug fixes and other routine changes to all libraries. * September 20, 2009: Release managers start QA checks. * October 4, 2009: branches/release closed for major code changes. Still open for serious problem fixes and docs changes. * October 11, 2009: branches/release closed for all library changes except when specific permission given by release manager(s). * October 18, 2009: Beta release target date. Further betas and/or release candidates as feedback dictates. * November 1, 2009: Release ship date.
