On the Google Antigravity Releases page ( Google Antigravity ), under the ‘Antigravity IDE’ tab, the listed 1.x.x versions (e.g., 1.0.55 to 1.0.35) are wrong and all of their download links return a 404 Not Found error.
Previously, the highest stable version in the 1.x.x series was 1.23.2. It seems the old release data was incorrectly mapped or lost during the recent update. Please restore the correct 1.x.x download links.
