First, Vapor alignment. Several merged fixes close gaps where Vapor silently diverged. Two examples tell the story: pull request 15787 resolves component tags from slot scope, and 15786 aligns setup component lookup order with the classic renderer. The same theme covers vee show through a Transition wrapping a slot…
Second, lifecycle and output correctness. Pull request 15776 fixes stale directive bindings, where a mounted hook could see old data if the element updated in the same scheduler flush. Pull request 15782 stops watcher callbacks from accidentally tracking dependencies when they run inside another effect, a…
