About Eclipse Theia
Theia ships on a steady six-week cadence, but its feed publishes contributor lists instead of changes.
Eclipse Theia is releasing minor versions roughly every six weeks — 1.72 through 1.75 since late May — with patch releases in between that list only commit hashes. The release entries themselves carry no readable changelog: each one links out to release notes and a breaking-changes page, then enumerates contributors and first-time contributors. The project is visibly active, with a wide and growing contributor base, but the feed does not say what any release contains.
