@Rocky In download starrocks page, I can not see Starrocks version 4.0 like 4.0.10-5b36164; only 3.5 and 4.1 why 4.0 is removed from download page?

It is not that StarRocks 4.0 has been "removed" or discontinued; rather, it has been moved to the background as StarRocks 4.1 is now the current feature release for the 4.x branch. Here are the key reasons why you likely only see 3.5 and 4.1 on the main download page: 1. Release Strategy: Latest of Each Major Branch The StarRocks download page typically highlights the latest minor version of each active major branch to simplify the choice for users: * StarRocks 4.1: The latest "current" release containing the newest features (like Multi-Tenant Data Management and Large-Capacity Tablets). * StarRocks 3.5: The latest minor version of the 3.x series, which is often preferred by users looking for a more mature/stable branch before making the jump to a new major version. 2. Version Maintenance Policy StarRocks officially maintains the three latest minor versions. As of May 2026, those versions are 4.1, 4.0, and 3.5. * StarRocks 4.0 is still active: You noted version

4.0.10-5b36164

. Indeed, version 4.0.10 was released as recently as May 9, 2026. This confirms the branch is still receiving bug fixes and security patches. * Replaced by 4.1: Once a new minor version (4.1) is released, it effectively replaces the previous one (4.0) as the "featured" download for that major line. 3. Compatibility & Downgrades There are specific compatibility rules between these versions: * Upgrade Path: You can upgrade from 3.5 to 4.0 and then to 4.1. * Downgrade Restrictions: If you upgrade to 4.1, you can only downgrade to 4.0.6 or later. This makes 4.1 the primary target for 4.x users, while 4.0 remains a critical bridge or fallback. Where to find StarRocks 4.0.10? If you specifically need version 4.0.10 (e.g., for compatibility or a specific fix), you can find it via: * GitHub Releases: The StarRocks GitHub Releases page lists all versions, including every patch for 4.0. * "All Versions" Link: On the official download page, look for a "View All Versions" or "History" link, which redirects to the full archive of binaries. Summary: The UI prioritizes 4.1 (Latest Features) and 3.5 (Latest Stable 3.x). Version 4.0 is still fully supported and maintained, but it is no longer the "recommended" starting point for the 4.x series now that 4.1 is available. References • release_notes/release-4.0.md
