Release Cycle of the Future

Release Cycle until now
release phases
alpha - development of everything (4-6 months)
beta - feature freeze & focus on stabilization (2-4 months)
release candidates & final release (0-2 weeks under pressure)
current supported versions
4.5 LTS (until 2015-03), 4.7 (until 2014-10)
6.1 (until 2014-10), 6.2 LTS (until 2017-03)

Long Term Support dilemma
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

Downsides Current Cycles
alpha & beta not tested in the wild
feature rush prior to LTS (… it’s about the next three years …)
too long feature freeze phase
high resources required for back porting fixes
low adoption of intermediate releases (between LTS)
little arguments for using intermediate releases

Improvements
LTS each 1,5 year, support for 3+ years
for early adopters: intermediate releases as „stable snapshots“
usable in production
smooth incremental upgrades possible
clear deprecation (API, code, TypoScript): only on major versions

Deprecation
minimum requirements and deprecations handled equally
system requirements defined when starting new major branch
browsers minimum support
PHP / MySQL minimum support
minimum requirements do not change in snapshots
deprecated stuff is kept until right after next LTS release
