Every ArcadeDB release announcement in one place, newest first. Each entry links to the release notes on the blog and to the complete list of issues and pull requests on GitHub Releases.

ArcadeDB 26.9.1 is the largest release we have ever shipped: 992 issues and pull requests closed, 1,500 commits. Full backups are 27.6x faster and no longer stall writers, a family of wrong-result defects in SQL and openCypher is closed, indexes are used where they were not, vector search opens in constant time, and six security advisories are patched.
ArcadeDB 26.8.1 is a major release: 381 issues and pull requests closed, 669 commits. Concurrent writes to unrelated records of the same page no longer conflict, vertex deletes no longer lose edges and are 5x faster, bloom filters land on compacted LSM indexes, and 13 security advisories are closed.
ArcadeDB 26.7.3 is a focused hotfix on top of 26.7.2: it closes three security advisories (two in the MCP server transport, one in the JavaScript/Java trigger authorization gate) and repairs a data-loss regression in the commutative super-node edge-append merge.
