For major releases that are in "Active development" or "Full support", minor versions are released approximately every three months, and their End-of-Life (EOL) is announced at least six months in advance. The latest minor release is supported as long as its underlying major release.
Bug and security fixes are managed differently depending on whether the underlying major release is in “Full support” or “Limited support”. For more information, read our Release Process.
General Principles
Semantic Versioning
Silverstripe CMS 3.2 onward, follows Semantic Versioning, which makes minor release upgrades (e.g. from 4.1 to 4.2) as painless as possible.
