v0.4.6

Node 26.x feature support, plus removal-safe flag injection.

Runtime

Text imports (import data from "./file.txt" with { type: "text" }) now defer to Node's native implementation on Node 26.5+, where nub previously used its own polyfill. Output is byte-identical across the boundary. (#395)

New Node experimental modules are enabled automatically wherever the running Node accepts the flag — no --experimental-* flag to pass:

Module	Available from	What it is
node:ffi	Node 26.1	Call native shared libraries directly from JS
node:vfs	Node 26.4	Virtual filesystem module
node:stream/iter	Node 25.9	Stream iterator helpers

Ambiguous ES modules now run on older Node. A .js file with ESM syntax and no "type": "module" — which bare Node on the compat tier refuses — is now detected and run as ESM under nub. (#402)

Flag-injection robustness

nub unflags Node features early by injecting --experimental-* flags on the versions that need them. Node removes some of those flags in later releases, and passing a removed flag is a startup abort (node: bad option, exit 9) before any code runs.

nub now intersects the flags it would inject with the target Node binary's actual accepted-flag set, so a flag the running Node no longer recognizes is dropped instead of crashing. A future Node that removes a flag needs no nub release. (#398)

Testing & internals

• Flag-drift snapshot CI — a scheduled job diffs Node nightly's experimental-flag set against a committed snapshot and fails when a flag is added or removed, so new Node flags are reviewed before nub claims them. (#402)
• A floating latest-Node leg was added to the version-matrix sweep. (ef6ff07)
• Cross-tier tests pin the text-import behavior on Node 22.13 / 24.4 / 26.5. (#397)
• A tsconfig resolution path was adjusted to satisfy the Rust 1.97 question_mark lint; behavior unchanged. (02ce797)
