 # Changelog
 
+## 2025-11-16 - 4.4.0 - feat(core)
+Add Bun and Deno runtime support, unify core loader, unix-socket support and cross-runtime streaming/tests
+
+- package.json: expose ./core_bun and ./core_deno in exports and add runtime-related keywords
+- Core dynamic loader (ts/core/index.ts): detect Bun and Deno at runtime and load corresponding implementations
+- New runtime modules: added ts/core_bun/* and ts/core_deno/* (response, types, index) to provide Bun and Deno CoreResponse/CoreRequest wrappers
+- Client streaming: SmartRequest no longer immediately deletes temporary __nodeStream and __rawStreamFunc props — CoreRequest implementations handle them; temporary properties are cleaned up after CoreRequest is created
+- Node.js request: core_node/request.ts converts web ReadableStream to Node.js Readable via stream.Readable.fromWeb and pipes it; also supports passing requestDataFunc for raw streaming
+- core_node/plugins: export stream helper and rework third-party exports (agentkeepalive, form-data) for Node implementation
+- CoreResponse for Bun/Deno: new implementations wrap native fetch Response and expose raw(), stream(), and streamNode() behavior (streamNode() throws in Bun/Deno with guidance to use web streams)
+- Tests: added unified cross-runtime streaming tests and separate unix-socket tests for Node/Bun/Deno with Docker-socket availability checks; removed old node-only streaming test
+- Docs/readme: updated to describe Node, Bun, Deno, and browser support, unix socket behavior per runtime, and new test conventions
