Node compat filled in several big gaps
Hooks and module-loader support were tightened again, including restoring Module.register/registerHooks behavior, improving nextLoad()/createRequire() edge cases, and fixing builtin redirects. Crypto, DNS, WASI preview1, node:test, node:trace_events, worker_threads, node:https, and diagnostics_channel also picked up targeted compatibility fixes.
Inspector and DevTools networking got much more useful
Network event plumbing was expanded so fetch(), WebSocket traffic, and node:http requests now surface in CDP even under plain --inspect. Deno also added response-body/post-data retrieval, correct disconnect notifications, hostname-based inspector binding, and process.debugPort reporting for a more Node-like debugging experience.
CLI and test workflows improved
deno ci landed as a frozen, lockfile-required install path for reproducible environments. deno check --watch now reruns on graph changes, deno install -g defaults bare package names to npm, and deno audit fix is accepted as a shorthand. On the testing side, Deno.test() now defaults sanitizers off, node:test gained watch-mode events and a Node-compatible TAP reporter, and JUnit output was rewritten locally.
Startup and binary size were trimmed
The startup snapshot was cut by about 27%, ICU data duplication was removed after the V8 upgrade, release builds switched to panic=abort, and networking/install paths shed a few dependencies and extra provider code. These changes should help cold-start cost and shipped binary size.
Other misc changes
- TypeScript libs now expose newer runtime APIs like
Math.sumPreciseandIntl.Locale.variants. createImageBitmapwas fixed for wide raw buffers.- Several dependency cleanups and small refactors landed across the workspace.
