VERSION goes to 1.0-alpha and CHANGELOG's [Unreleased] becomes [1.0-alpha] dated 2026-08-04. Every item on the #367 checklist is closed: the open bugs (#358, #362, #363, #364, #376), the docs accuracy pass, the changelog, the single-engine and cross-engine benchmark re-measures, and a full five-major matrix green at 112 suites on each of PG15 through PG19. The extension's own default_version stays at 1.0-dev, and the changelog now says so rather than leaving it to be discovered. That field governs ALTER EXTENSION UPDATE; moving it needs an upgrade script that does not exist, and breaking installs to make a version string tidy is the wrong trade. SELECT extversion therefore reports 1.0-dev on a 1.0-alpha build. Adds a known-limitations section, because an alpha that ships its sharp edges in the tracker only is an alpha that hides them: the grouped parallel arm declined on expression grouping keys (#369), the fetch cache's real memory bound (#364), the index-fetch penalty being bounded rather than modelled (#376), and point-lookup cost growing with table width.
