 # Changelog
 
+## 2025-10-10 - 2.4.2 - fix(deno)
+Enable additional Deno permissions for runtime adapters and add local dev settings
+
+- Add --allow-sys, --allow-import and --node-modules-dir to the default Deno permission set used by the Deno runtime adapter
+- Include the new permission flags in the fallback permissions array when constructing Deno command args
+- Add .claude/settings.local.json to capture local development permissions and helper commands
+
+## 2025-10-10 - 2.4.1 - fix(runtime/deno)
+Enable Deno runtime tests by adding required permissions and local settings
+
+- ts/tstest.classes.runtime.deno.ts: expanded default Deno permissions to include --allow-net, --allow-write and --sloppy-imports to allow network access, file writes and permissive JS/TS imports
+- ts/tstest.classes.runtime.deno.ts: updated fallback permissions used when building the Deno command to match the new default set
+- Added .claude/settings.local.json with a set of allowed local commands/permissions used for local development/CI tooling
+
+## 2025-10-10 - 2.4.0 - feat(runtime)
+Add runtime adapters, filename runtime parser and migration tool; integrate runtime selection into TsTest and add tests
+
+- Introduce RuntimeAdapter abstraction and RuntimeAdapterRegistry to manage multiple runtimes
+- Add runtime adapters: NodeRuntimeAdapter, ChromiumRuntimeAdapter, DenoRuntimeAdapter and BunRuntimeAdapter
+- Add filename runtime parser utilities: parseTestFilename, isLegacyFilename and getLegacyMigrationTarget
+- Add Migration class to detect and (dry-run) migrate legacy test filenames to the new naming convention
+- Integrate runtime registry into TsTest and choose execution adapters based on parsed runtimes; show deprecation warnings for legacy naming
+- Add tests covering runtime parsing and migration: test/test.runtime.parser.node.ts and test/test.migration.node.ts
+
+## 2025-09-12 - 2.3.8 - fix(tstest)
+Improve free port selection for Chrome runner and bump smartnetwork dependency
+
+- Use randomized port selection when finding free HTTP and WebSocket ports to reduce collision probability in concurrent runs
+- Ensure WebSocket port search excludes the chosen HTTP port so the two ports will not conflict
+- Simplify failure handling: throw early if a free WebSocket port cannot be found instead of retrying with a less robust fallback
+- Bump @push.rocks/smartnetwork dependency from ^4.2.0 to ^4.4.0 to pick up new findFreePort options
+
+## 2025-09-12 - 2.3.7 - fix(tests)
+Remove flaky dynamic-ports browser test and add local dev tool settings
+
+- Removed test/tapbundle/test.dynamicports.ts — deletes a browser test that relied on injected dynamic WebSocket ports (reduces flaky CI/browser runs).
+- Added .claude/settings.local.json — local development settings for the CLAUDE helper (grants allowed dev/automation commands and webfetch permissions).
+
+## 2025-09-03 - 2.3.6 - fix(tstest)
+Update deps, fix chrome server route for static bundles, add local tool settings and CI ignore
+
+- Bump devDependency @git.zone/tsbuild to ^2.6.8
+- Bump dependencies: @api.global/typedserver to ^3.0.78, @push.rocks/smartlog to ^3.1.9, @push.rocks/smartrequest to ^4.3.1
+- Fix test server static route in ts/tstest.classes.tstest.ts: replace '(.*)' with '/*splat' so bundled test files are served correctly in Chromium runs
+- Add .claude/settings.local.json with local permissions for development tasks
+- Add .serena/.gitignore to ignore /cache
+
 ## 2025-08-18 - 2.3.5 - fix(core)
 Use SmartRequest with Buffer for binary downloads, tighten static route handling, bump dependencies and add workspace/config files
