    aronwk released this 2025-01-27 18:01:37 -06:00 | 3125 commits to main since this release

    Backwards incompatible changes in this release:

    The dolt_branches system table has changed. The table now has a ninth column to indicate that a branch is dirty. Some software may depend on the dolt_branches table having exactly eight columns, and will require updates to work with this latest version.

    Per Dolt’s versioning policy, this is a minor version bump because these changes may impact existing applications. Please reach out to us on GitHub or Discord if you have questions or need help with any of these changes.
