First, long dev sessions should get leaner and more stable. Pull request 100374 addresses heap growth tied to Node's internal module parent links keeping old compilation graphs alive after cache invalidation. In testing with 30 edits and server hot reloading disabled, heap use after forced garbage collection grew…
Second, Turbopack is closing a parity gap with Webpack for Route Handlers. Pull request 100372 fixes a failure where a Route Handler rendering a flight payload with client components produced an empty client module list and the error could not find the module in the React client manifest. The cause was client…
