Bundle can now emit rolled-up declaration files (
229ddc0)
deno bundle gained a --declaration flag that produces a single .d.ts alongside each bundle output. This makes bundling usable for publishing TypeScript libraries without a separate declaration build step.
Workspace installs now create member-local node_modules (a4e9966)
deno install now lays out node_modules inside each workspace member, matching npm/pnpm expectations and fixing native Node tooling that runs from within a subpackage. It also prunes stale links and keeps member .bin entries in sync, which closes a real workspace resolution gap.
Console/inspect moved from JS to Rust (
d400a15)
The console formatting and inspection stack was ported to Rust, turning 01_console.js into a thin shim and moving the heavy formatting logic into native code. This is a substantial runtime refactor that should improve performance and reduce JS snapshot weight.
Formatter switches HTML/XML/SVG and components to lax-markup (bf844be)
deno fmt now uses lax-markup for markup formatting, replacing the older formatter for HTML, XML, SVG, and component/template cases. The change is aimed at safer, more predictable formatting that preserves text and inline content byte-for-byte unless whitespace changes are provably harmless.
Formatter switches CSS to lax-css (37c97f4)
CSS, SCSS, and Less formatting now go through lax-css instead of malva, and malva is removed from the dependency tree. This should fix long-standing CSS formatting issues while keeping formatting whitespace-only and syntax-preserving.
CSS module imports are now supported behind an unstable flag (08a3995)
Deno added a prototype for import ... with { type: "css" }, returning a CSSStyleSheet for browser-style module graphs. This is a notable new capability for SSR/testing web components and unmodified browser modules, though it remains behind --unstable-raw-imports.
Install now caches workspace member resolution more accurately (e855ab5)
Remote 404 responses are now negatively cached with a short TTL instead of being re-requested on every start. That should reduce repeated fetches for missing JSR or dynamic-import targets and avoid unnecessary network churn.
Test output now shows sub-millisecond durations (
af9628d)
Test reporters and related plumbing were updated so timings can display below the millisecond. This is a small but user-facing improvement to test diagnostics.
Coverage summary no longer panics without a common root (9cf4f7d)
The coverage summary reporter now handles inputs that don’t share a common root instead of crashing. This is a targeted robustness fix for a real reporter edge case.
REPL regex literal highlighting was fixed (
c6765be)
The REPL editor now highlights regex literals correctly. It’s a focused UX fix, but not a broad functional change.
Other misc changes
- Lockfile auto-resolves git merge conflicts in
deno.lock. - Dependency/version bumps and formatter/test updates for the new markup/CSS tooling.
- Internal plumbing updates for CSS module imports and bundle declaration emission.
