Dolt v2.0.2 now supports ON DELETE SET DEFAULT and ON UPDATE SET DEFAULT foreign‑key actions at table creation.

Why it matters: If your schemas define FK default actions, upgrade to v2.0.2 immediately; otherwise treat as FYI.

Summary

  • 11040: fixed compat tests for a post-2.0 CI
  • 11038: remove adapative encoding matrixes
    Now that adaptive encoding is on by default, we don't need to double our CI testing efforts anymore.
  • 11035: Refactor prollyWriteSession and prollyTableWriter for individual table flushing
    This PR refactors flushing logic between prollyWriteSession and prollyTableWriter.
    Now, the prollyTableWriter is in charge of materializing the table and handling the auto increment logic, while the prollyWriteSession is in charge of keeping the workingSet up to date.
    The flush all table logic has been reworked in prollyWriteSession to use channels instead of a mutex.
    Additionally, this PR allows us to flush individual tables rather than every table in the session; this avoids concurrency overheads and no-op flushes.
  • 11032: Let merge-permission users write through dolt_conflicts_
    Adds a branch-control carve-out so a user with only Permissions_Merge on a branch can resolve a merge that produced data conflicts by writing through dolt_conflicts_<t> and via DOLT_CONFLICTS_RESOLVE. Lets a PR reviewer on the SQL workbench finish a conflicting merge without being granted full write access on the target branch.
  • 11030: Gate DELETE on dolt_conflicts_ with branch_control Write permission
  • 11029: Allow index lookups on DOLT_DIFF table function.
    Currently, the DOLT_DIFF table function does not expose any indexes. But it can.
  • 11020: .github: Factor out build-dolt and setup-dolt-config actions. Use them from workflows that want dolt binaries, like bats and sql-server-integration tests.
  • 10853: chore: fix function name in comment to match actual function
    fix function name in comment to match actual function
