v5.0.0-alpha.129 Jun 2026 pre-releaseRelease notes
Open source →Completes 22ece5199 (open 5.0 dev line): root is 5.0.x-dev but the
self-referential api-platform/* constraints were left at ^4.4@alpha,
which is unresolvable in the component split-tests (published 4.4
alphas require metadata ^4.4, conflicting with the 5.0 root). -
v4.4.0-alpha.312 Jul 2026 pre-releaseRelease notes
Open source →-
perf(state): skip response body on HEAD requests
-
feat(symfony): add enable_head_request_optimization config flag
HEAD responses now omit some observable headers (Content-Length, per-item cache tags); per semver that is a backward-
incompatible behavior change, so this commit ships an opt-out flag — setenable_head_request_optimization: falseto restore the
prior GET-equivalent behavior.- fix(state): do not list HEAD in Allow header without GET operation
