Hello, it's Friday, October 9th, 2026, you're listening to Next Js Daily.
Today's lead: Turbopack is laying groundwork for more reliable chunking while sharply cutting tracing overhead, and release automation is getting simpler.
First theme: chunk group correctness. A multi-part stack canonicalizes how chunk groups are identified so incidental ordering doesn't change identity, that's PR 98733, then batches multiple groups into a single chunking task with no output change, PR 99686, and registers exactly the groups that get chunked,…
Second: observability on a diet. Three merged tracing changes remove separate allocation rows and attach them to enter and exit events, drop exit-enter pairs with almost no gap, and send only deltas when counters change — that's PR 99778, 99780 and 99779. Those rows were about two-thirds of a typical trace, and the…
Third: releases and build polish. PR 99807 replaces per-version release branches with two long-lived L-T-S refs for active and maintenance, with follow-ups for older-tag branches in PR 99929 and non-L-T-S support in PR 99948. For daily work, the build route table now shows the correct static symbol for collapsed…
