 # Changelog
 
+## 2025-11-16 - 4.3.8 - fix(core)
+Ensure correct ArrayBuffer return, fix fetch body typing, reorganize node-only tests, and bump tsbuild devDependency
+
+- core_node: Fix arrayBuffer() to ensure an ArrayBuffer is returned (avoid returning SharedArrayBuffer) to improve interoperability when consuming binary responses.
+- core_fetch: Cast request body to BodyInit when assigning to fetch options and preserve duplex = 'half' for ReadableStream bodies to satisfy typings and streaming behavior.
+- tests: Reorganize tests into Node-only variants (rename/remove multi-platform test files to test.*.node.ts) to separate platform-specific test coverage.
+- chore: Bump devDependency @git.zone/tsbuild from ^2.6.8 to ^2.7.1.
+
 ## 2025-11-01 - 4.3.7 - fix(ci)
 Update dependencies, add deno.lock, and reorganize tests for browser and Node environments
