  3. 14.4Editor 14.4: more detailed export versionsDec 9, 2025
    This is a very small update. It lets the export screen show the exact minecraft versions that are supported by an export (e.g. 1.21.10 or 1.20.6) rather than just the major version (e.g. 1.21 or 1.20). Note that this is an Editor-only update, so this release does not contain a plugin release, since it would be identical to Custom Items 14.3.
