fix(es/es2015): preserve this in static field parameters (#12085) **Description:** Preserve lexical `this` while lowering arrows with rest/default parameters in static class field initializers. Static public and private fields now use initializer-local captures, matching instance-field behavior. Adds snapshot and execution coverage for static and instance `Scope.module` calls, and updates the existing static-field regression snapshot. **BREAKING CHANGE:** None. **Related issue (if exists):** Fixes #12084 **Validation:** - `cargo test -p swc_ecma_transforms_compat` - `cargo test -p swc_ecma_compat_es2015` - `cargo fmt --all` - `cargo clippy --all --all-targets -- -D warnings` --------- Co-authored-by: Labor0 Bot <279936132+labor0-bot[bot]@users.noreply.github.com>

chore: Publish `@swc/types@v0.1.28` `@swc/types@0.1.27` was published on 2026-06-16, from the version bump in b182fbd5bc (#11917). `reactCompiler.environment.enableFunctionOutlining` was added to `packages/types/index.ts` later, in 52b78aa1d7 (#12030, 2026-07-23), without a version bump, so the field is missing from every published tarball. `@swc/types` is published only by the manual `publish-misc-packages.yml` workflow and is not part of the `@swc/core` release pipeline, so the shipped typings drifted from the Rust config, which has supported the option since `@swc/core` 1.15.47.

fix(plugin): make raw byte reconstruction unsafe (#12089) **Description:** Makes `PluginSerializedBytes::from_raw_ptr` an unsafe public function with a precise safety contract, and removes the clippy suppression that hid its raw-pointer dereference. Audits every wasm hygiene, host-allocation proxy, and procedural-macro caller with narrow unsafe blocks and ABI-specific safety justification. Also adds positive raw-buffer coverage and a compile-fail API test. Validated the affected crates, plugin feature and wasm compilation paths, the full plugin backend integration suite, formatting, and workspace clippy with warnings denied. **BREAKING CHANGE:** `PluginSerializedBytes::from_raw_ptr` and the `plugin_transform`-generated `__transform_plugin_process_impl` entry point are now unsafe. Direct callers must use an unsafe block and uphold the documented pointer, length, initialization, alignment, and lifetime requirements. **Related issue (if exists):** Closes #11988 --------- Co-authored-by: Labor0 Bot <279936132+labor0-bot[bot]@users.noreply.github.com> Co-authored-by: Donny/강동윤 <kdy.1997.dev@gmail.com>
