deno install and deno add now default unprefixed packages to npm (
6b44f6d)
This removes the need to type npm: for ordinary packages, so commands like deno install express react and deno add ajv now resolve to npm by default. It’s a practical UX improvement that makes the package workflow feel much closer to standard JS tooling.
Node child_process sync APIs gain timeout, killSignal, and pid support (43deeb2)
spawnSync/execSync/execFileSync now accept timeout and killSignal, return pid, and report timeout-killed processes with Node-like error/signal behavior. This closes an important compatibility gap for tooling that depends on sync process control.
Deno.test() no longer fails by default on leaked ops/resources (fee0589)
The test runner flips sanitizeOps and sanitizeResources to false unless explicitly enabled, reducing noisy failures from incidental async work and open resources. This is a meaningful behavior change for existing test suites and should make defaults much less surprising.
Node fd-based sockets and handles get broader support (4e6eb1e, 607c73f, ff775b2)
Several Node compat fixes landed for real OS file descriptors: net.Socket({ fd }), TCP.open(fd), and numeric stdio entries in child_process now work with actual fds instead of resource IDs. Together these changes unblock more Node-style code that passes around inherited or opened descriptors.
deno tsconfig was added, then immediately reverted (d6b5810, 863bf0b)
The day briefly introduced a new unstable deno tsconfig subcommand for generating TypeScript config files, but it was reverted after the approach was deemed unsuitable. The intended functionality will be folded into deno install instead.
Other misc changes
- Lint defaults changed for
no-process-global/no-node-globals(1 commit). - Minor Node compat and test harness tweaks.
- Test and fixture updates for the new/changed behaviors.
