This page is a router for the v1.4 GA narrative: it does not duplicate the GA matrix; it points to the canonical planning artifacts and packaged maintainer docs.
Executed means we ran the listed procedure or produced the named artifact for the milestone. Waived means a matrix row was intentionally not re-run for that cut, with a documented substitute (often CI) where applicable. Neither label moves integration or deployment risk to the library — your host application still owns those boundaries.
