Deno drops its TypeScript fork for stock TS (
34d5929)
Deno now runs on upstream typescript@6.0.3 instead of its forked compiler, removing the patched 00_typescript.js bundle and several ts.deno.* host hooks. This is a major internal shift that simplifies future TS upgrades, but it also changes some LSP/check behavior to match stock TypeScript.
Unix socket access now requires net permission too (f323745)
Connecting to node:net Unix sockets now requires --allow-net=unix:<path> in addition to filesystem access. The new shared permission helper also handles abstract Linux sockets and tightens the security model around local IPC endpoints like Docker and dbus.
deno check now errors on export = in ES modules (23847c9)
TS1203 is no longer downgraded to a warning, so export = in ESM surfaces as a hard error. That brings Deno in line with stock TypeScript and removes a long-standing compatibility exception.
Deno serves a single @types/node copy in type-checking (1d4e6c1)
When a project has its own @types/node, Deno now points lib.node.d.ts at that resolved file instead of also loading the built-in copy. This avoids duplicate node declarations in the program and unblocks the single-global-table behavior needed by the TypeScript un-fork.
Transitive @types/node dependencies are detected (72edd4f)
If @types/node is only present transitively, Deno now finds that installed copy and serves it to tsc instead of loading both the built-in and nested versions. This fixes duplicate-identifier failures for packages like Express/Koa that bring node types in indirectly.
Web-platform globals now defer to DOM typings when present (8959589)
Deno's bundled lib.deno_*.d.ts files were reshaped so globals like Request, Performance, navigator, and CustomEvent can reuse DOM definitions when lib.dom is loaded. This reduces conflicts between Deno's libs and stock TypeScript's DOM globals as the fork is removed.
Packument cache now records fetch format (7d0a481)
fast-registry-json and npm cache metadata now track _deno.packumentFormat, letting Deno distinguish a full registry packument from an abbreviated one. That fixes cache behavior when registries omit publish-time data and prevents unnecessary re-fetches.
Coverage now counts branch junction lines more accurately (
95407f0)
A line shared by both branch arms is now considered covered if either arm runs. This improves LCOV/reporting accuracy for single-arm branch execution.
Docker socket-style permission checks are enforced consistently (f323745)
Unix-socket path checks were factored into ext/net so both native socket ops and node-compat paths use the same validation logic. The change also preserves abstract socket handling on Linux-style abstract addresses.

@deno/patchverbump to handle macOS binaries and removal of Google Cloud auth. - Re-enabled and adjusted LSP/check tests for the TypeScript un-fork.
