Changes

hpqtypes-effectful-1.2.0.0 (2026-09-28)

  • Compatibility with hpqtypes >= 1.15.0.0.
  • Rename the WithNewConnection constructor of the DB effect to WithNewSession, to match the rename of withNewConnection to withNewSession in hpqtypes.
  • A database session is now bound to the thread that started it. If another thread runs a query in that session, the query throws ThreadMismatchError. To run queries from another thread, start a separate session there with withNewSession.
