 ## Supported versions {#supported-versions}
 
-At any point in time, the core development team will support a set of releases to varying levels:
-
-- The status of major releases is determined by the [roadmap](http://silverstripe.org/roadmap)
-- Minor releases of major releases in "active development" or in the "bug and security fixes" phase are released roughly 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 the underlying major release
-- API changes and major new features are applied to the master branch, to be included in the next major release
-- New APIs can be applied to the current minor release of major releases in "active development", but should usually be marked as "internal" APIs until they're considered stable
-- Enhancements are applied to the next minor release of major releases in "active development"
-- Non-critical bugfixes and all security fixes are applied to all supported minor releases of major releases in "active development" or in the "bug and security fixes" phase
-- Critical bugfixes and [critical security fixes](#severity-rating) are applied to the all minor releases of major releases in "active development", "bug and security fixes" or "security fixes only"
-- [Non-critical security fixes](#severity-rating) are backported to releases in the "security fixes only" phase on a best effort basis
-- Any patches applied to older minor releases are merged up regularly to newer minor releases (in the same major release)
-- Any patches applied to older major releases are merged up regularly to newer major releases
