First, locking on combined queries. Two proposals, PR 22160 and PR 22163, address the same ticket, 37432. Today, calling select for update after a union, intersection, or difference is silently dropped — your code looks locked but isn't. Both fixes raise a not-supported error instead, consistent with how Django…
Second, stale data and backend reliability. PR 22164 makes Content Type object lookups raise a lookup error when the underlying model has been removed, instead of failing downstream with a confusing error from a missing model. And PR 22161 preserves trigger terminators in Oracle SQL scripts, fixing cases where…
Finally, speed, observability, and cleanup. PR 22166 speeds up post-commit callback dispatch from quadratic to linear overhead by walking the queue once and clearing slots, without changing callback behavior.
