News of the week of August 25, 2025: the two fools unpack the expected breaking changes to TSConfig in the upcoming 6.0 release, explain Node's latest LTS notable changes, and cover the latest in the JS trademark case from Deno. Plus, a PSA if you use Nx! From the community: making the case to migrate to Node's type stripping, a peek at Vitest 4, Zod's new Codecs feature, refactoring types, Rolldown is the opposite of a letdown, and a bunch of neat libraries/framework releases to watch.
