In Epoch, both the Application Operation (AOC) and collectors follow Semantic Versioning:

AOC Versioning

The Epoch AOC is always being updated with improvements and fixes; both major and minor. While backwards compatibility is usually maintained, there are some changes that make it necessary to no longer support some collector versions.

Collector Versioning

Epoch collectors also undergo changes and improvements, resulting in differing versions. By default, the collectors will auto-upgrade themselves to the lastest version when one is available, however if turned off they will not.

As a general policy, collector versions n-2 are supported.
n being the latest version, as well as the previous 2 versions.
