The process is the same for these additional release as for a .0 release. -At most two release branches are formally maintained at any given time: the -latest release and the latest release designed as LTS.

An LTS release has the distinction of being maintained for +longer than a standard release. + +LTS releases will receive bug fixes until the point that another LTS is +released. At that point, the old LTS will receive an additional year of +critical and security fixes. Critical fixes are those that are required to +ensure basic operation (e.g. memory leak fixes, crash fixes). Security fixes +are those that address concerns about exploitable flaws in OVN and that have a +corresponding CVE report. + +LTS releases are scheduled to be released once every two years. This means +that any given LTS will receive bug fix support for two years, followed by +one year of critical bug fixes and security fixes. + Release Numbering -----------------
