Release Cycle
LTS-only-users from TYPO3 4.5 to TYPO3 6.2
ignoring versions 4.6, 4.7, 6.0 and 6.1 = four versions
4.6: caching framework & race conditions
4.7: Extbase persistence features
6.0: file abstraction layer & namespaces
deprecations - methods are removed two versions later
statistics: ~ 60-70% are LTS-only-users

Release Cycle
public testing feedback
alpha & beta not tested
but release candidates are
feature rush prior to LTS
… it’s about the next three years …
feature freeze phase is too long
bugfix vs. feature/refactoring
