Support timeline

This timeline outlines how long different versions of SilverStripe CMS will remain supported. 'Being supported' or 'support' means that SilverStripe Ltd will be releasing security patches, fixing major bugs, testing, and providing technical documentation to support these versions. This will not cover issues related to individual sites e.g custom code.

Please note - this timeline is is an indication of our plans and not a contractual obligation; if you require a committed support contract for a given duration, please contact [email protected]. The release dates of future releases are provisional and subject to change. It is reasonable to assume that if a release is delayed, its entire support timeline is pushed forward.

General Principles

Semantic Versioning

SilverStripe 3.2 onward, follows Semantic Versioning, which makes minor release upgrades (e.g. from 4.1 to 4.2) as painless as possible.

Longer versions, regular shorter minor releases 

SilverStripe 3.2 and onward, we support major versions for longer periods of time, with regular minor version releases that are supported for shorter periods 

In it for the longhaul

SilverStripe 4 onward, some releases are marked as "LTS". We recommend that customers seeking multi-year stability make use of LTS (Long-Term Support) releases.
