 # Changelog
 
+## 2025-11-19 - 3.0.0 - BREAKING CHANGE(tapbundle_serverside)
+Rename Node-specific tapbundle module to tapbundle_serverside and migrate server-side utilities
+
+- Change public export in package.json from ./tapbundle_node to ./tapbundle_serverside — consumers must update imports to @git.zone/tstest/tapbundle_serverside
+- Move and re-create Node-only implementation files under ts_tapbundle_serverside (plugins, paths, classes.tapnodetools, classes.testfileprovider, index, tspublish.json) and remove legacy ts_tapbundle_node sources
+- Update internal imports and tests to reference the new tapbundle_serverside path (e.g. test/tapbundle/test.node.ts updated)
+- Update documentation (readme.md and readme.hints.md) to describe the new tapbundle_serverside export and its server-side utilities
+- Ensure build outputs and publish metadata reflect the new module directory (tspublish.json order preserved)
+
 ## 2025-11-19 - 2.8.3 - fix(dependencies)

+
+Use `@git.zone/tstest/tapbundle_serverside` when your tests:
+
+- Run exclusively on Node.js server-side (*.node.ts test files)
+- Need to execute shell commands or interact with the file system
+- Require environment variable management with secure on-demand prompts
+- Test HTTPS servers and need self-signed certificates
+- Interact with databases (MongoDB) and need ephemeral test instances
+- Work with object storage (S3-compatible) and need local testing
+- Require test assets like Docker images or other downloadable files
+
+**Important:** tapbundle_serverside utilities are NOT available in:
+- Browser environments
+- Deno runtime
+- Bun runtime
+
+For cross-runtime tests, only import tapbundle_serverside in `.node.ts` files where you need server-side specific functionality.

 ## tapbundle Protocol V2
 
 tstest includes an enhanced TAP protocol (Protocol V2) that extends standard TAP 13 with additional metadata while maintaining backwards compatibility.

+⚠️ **Server-Side Only (Node.js)**: All utilities in this module are designed exclusively for server-side testing in Node.js runtime. They provide functionality like shell command execution, file system operations, and process management that only make sense on the server.

+**NOT available in:**

-For multi-runtime tests, use these utilities only in `.node.ts` test files.
+**Important:** Import tapbundle_serverside only in tests that run exclusively on the server-side (`.node.ts` test files). For cross-runtime tests, these utilities will fail in non-Node environments.
