@sapphi-red does rolldown still need this feature? |

Retitled from On the change itself: this Better approach: put it behind conditional compilation (a cargo feature, off by default), so the size cost is gone from normal builds but we can still flip it on when we need to chase a deadlock — instead of having to re-add the feature and rebuild mid-incident. If you'd still rather just remove it, I won't block it. |

@claude[agent] we can't remove this feature, need to document along the feature usage in Cargo.toml #8702 (comment) |

Keep the napi `tracing` feature enabled and document the reason in `Cargo.toml`. With the feature on, `#[napi]` logs every binding call, which helps debug deadlock issues like #7289 by showing which napi function is pending.

## [1.1.2] - 2026-06-18 ### 📝 Notable tsconfig behavior changes These ship via the `oxc_resolver` 11.21.3 bump (#9841) and affect `resolve.tsconfigPaths` (Vite 8 resolves through oxc-resolver): - **Honor explicit non-TS extensions in `include`** (oxc-project/oxc-resolver#1213). `compilerOptions.paths` now resolve for importers whose extension is explicitly listed in a tsconfig's `include` (e.g. `src/**/*.vue`, `src/**/*.svelte`). Previously oxc-resolver filtered importers by extension before evaluating the `include` globs, so a `.vue`/`.svelte` file listed in `include` never matched its project and its `paths` were skipped. This unblocks the default create-vite Vue + TS layout (a solution-style root plus a referenced `tsconfig.app.json` that declares `paths` and `include: ["src/**/*.ts", "src/**/*.vue"]`). Matches vue-tsc and svelte-check, which register these extensions via TypeScript's `extraFileExtensions`. - **No fallback to the outermost tsconfig in auto-discovery** (oxc-project/oxc-resolver#1220). Auto-discovery no longer attaches the topmost ancestor `tsconfig.json` to a file that no project actually owns (via `files` / `include` / project references). Previously such a file inherited the outermost ancestor's `paths` / `baseUrl`, leaking aliases into files that project does not own. oxc-resolver now returns no config in that case, matching tsserver / typescript-go, which route such files to an inferred project with no aliases. ### 🚀 Features -
