Good morning, it's Monday, November 2nd, 2026, and you're listening to your Ruby on Rails briefing.
The lead pattern is default ordering getting consistent. Four separate changes fix places where the newer default order concept was ignored, leaked, or couldn't be removed.
First, preloading and batching. Pull request 59497 fixes preloading a has-many-through association that uses default order, which was silently dropping that order while lazy loading kept it. Pull request 59523 fixes in-batches with use-ranges keeping an ignored default order, adding a needless order-by to each batch…
Second theme is output hardening, mostly small security and correctness fixes. Pull request 59511 percent-encodes the preload link header so a greater-than sign in a URL can't break out into fake link parameters, with a follow-up in 59520 to skip that work when no encoding is needed. Related work tightens streamed…
Third is performance by removing repeated work. Pull request 59505 avoids hashing the query cache key twice more on a miss, and 59518 proposes memoizing query attribute hashing. Pull request 59493 speeds up sum with a block by dropping an intermediate array, and another fix skips dynamic…
