This timeline outlines how long different versions of SilverStripe CMS will remain supported, based on our release process. '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. Subscribe to release announcements to keep updated. Please read our Update on SilverStripe 5.x from Sept 2018.
Support timeline table
End of Life (EOL) Date
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.
