Full changelog

on_conflict option for enqueue — pass on_conflict="skip" to silently skip jobs whose dedupe_key already exists instead of raising. Default remains "raise". Also exposed on the CLI. (#681)

Priority preserved when merging queued and stale jobs in dequeue — a stale high-priority job could previously be starved indefinitely behind a stream of fresh lower-priority work (regression from #607). The merged set is
now ordered priority DESC, id ASC across both sources. (#684)

Test suite now runs in parallel via pytest-xdist; container startup and TTL cache tests deflaked.

@wjmorland for proposing the on_conflict feature (#678) and reviewing the implementation.
@vedarolap for the detailed report on priority loss in the dequeue merge (#684).
