+VOLTHA Releases
+===============
+
+VOLTHA, up until the 2.8 release had a tight development and release schedule of 3 months.
+Starting June 2021 operates on a 6 months release schedule, with a Long Term Support release every 18 months.
+Long Term Support means that throughout the lifetime of a release there is a commitment to update,
+patch and maintain the software.
+
+VOLTHA process for releases is as follows:
+
+- each LTS release has an 18 months support period with bug fixes and testing.
+- LTS releases are 18 months apart.
+- VOLTHA has 6 month release cycles.
+- Two interim releases between LTS versions.
+- Bugfixes will be back ported to LTS (if applicable) from master and interim release.
