Built-in snapshot testing for deno test (
2ac9a90)
deno test now supports t.assertSnapshot(actual, options?) plus a first-class --update-snapshots/-u flag. Snapshots use the same __snapshots__/<test file>.snap format as @std/testing/snapshot, making migration from userland snapshot helpers straightforward.
node:test gains mock.module() support (e38a472)
Deno's Node compatibility layer now implements mock.module(specifier, options) for swapping modules during tests, including ESM import() and CJS require() paths. The mock context can be restored explicitly and integrates with broader mock reset/restore flows, matching newer Node behavior.
deno install can seed from bun.lock (1a62c3c)
First-run deno install now recognizes a sibling bun.lock and can seed deno.lock from it, extending the importer chain after npm and pnpm lockfiles. This makes Deno easier to adopt in Bun-based repos without a manual lockfile conversion step.
PnPM lock seeding now handles workspaces and catalog: deps (dcfb5ed)
The pnpm importer now walks every importer instead of only the root, so workspace member dependencies are preserved when seeding deno.lock. It also resolves pnpm catalog entries, avoiding incomplete or empty seeded locks in monorepos that rely on cataloged versions.
Coverage now merges hash/query variants of the same module (
e8a9000)
deno coverage now normalizes file:, http:, and https: URLs by stripping search params and fragments before merging ranges. That fixes duplicate partial entries when the same source is loaded as mod.ts, mod.ts?x, or mod.ts#y.
node:test hook ordering and error handling fixed (9855054)
The Node test polyfill now runs before()/after() hooks once per context in the right places, instead of leaking them across subtests. This also improves failure behavior around nested subtests and aligns Deno more closely with Node's hook semantics.
Workspace npm members now link into root node_modules by name (
717715a)
Workspace members that are themselves npm packages are now symlinked into the root node_modules using their real package name. That unblocks external Node tools that resolve through node_modules and previously couldn't find bare workspace members.
deno update --lockfile-only gets stale-cache protection (73ba7ce)
The outdated/update flow now refetches npm metadata for packages that may move within their existing version ranges, instead of trusting stale cached packuments. This closes a case where deno outdated reported an update but --lockfile-only failed to advance the lockfile.
node:child_process IPC no longer panics on empty buffers (
5967471)
Sending zero-length Buffers or typed arrays over advanced IPC no longer crashes the runtime during deserialization. Empty-backed ArrayBuffers are now handled safely instead of unwrapping a null backing store.
deno pack surfaces slow type diagnostics (
0b96ea9)
Pack now keeps slow type-check diagnostics visible instead of hiding them, which should make packaging failures and type issues easier to diagnose.
Other misc changes
- Lazy-loading and startup/perf work for
node:buffer,node:timers, and macOS frameworks - Test fixture/version bumps and test flake annotations
- Smaller install, doctest, and node-worker behavior fixes
