Pull request 22132 fixes JSON and H store form fields crashing with a server error on deeply nested input — about four kilobytes is enough to exceed the recursion limit. It now catches the recursion error and returns a validation message instead. Pull request 22144…
Second, database overhead is down. Pull request 22141, linked to commits c07486b and adeef10, reduces the cost of building many-to-many related managers by moving relation-only setup to the class level and skipping database router and connection lookups for reverse foreign key managers when not needed.
