 # Changelog

+## 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
+
+- ts_tapbundle_node/classes.testfileprovider.ts: switch to SmartRequest.create().url(...).get() and convert response to a Buffer before writing to disk to fix binary download handling for the Docker Alpine image.
+- ts/tstest.classes.tstest.ts: change server.addRoute from '*' to '(.*)' so the typedserver static handler uses a proper regex route.
+- package.json: bump several dependencies (e.g. @api.global/typedserver, @git.zone/tsbuild, @push.rocks/smartfile, @push.rocks/smartpath, @push.rocks/smartrequest, @push.rocks/smartshell) to newer patch/minor versions.
+- pnpm-workspace.yaml: add onlyBuiltDependencies list (esbuild, mongodb-memory-server, puppeteer).
+- Remove registry setting from .npmrc (cleanup).
+- Add project/agent config files: .serena/project.yml and .claude/settings.local.json for local tooling/agent configuration.
+
+## 2025-08-16 - 2.3.4 - fix(ci)
+Add local Claude settings to allow required WebFetch and Bash permissions for local tooling and tests
+
+- Add .claude/settings.local.json to configure allowed permissions for local assistant/automation
+- Grants WebFetch access for code.foss.global and www.npmjs.com
+- Allows various Bash commands used by local tasks and test runs (mkdir, tsbuild, pnpm, node, tsx, tstest, ls, rm, grep, cat)
+- No runtime/library code changes — configuration only
+
+## 2025-08-16 - 2.3.3 - fix(dependencies)
+Bump dependency versions and add local Claude settings
+
+- Bumped devDependency @git.zone/tsbuild ^2.6.3 → ^2.6.4
+- Updated @git.zone/tsbundle ^2.2.5 → ^2.5.1
+- Updated @push.rocks/consolecolor ^2.0.2 → ^2.0.3
+- Updated @push.rocks/qenv ^6.1.0 → ^6.1.3
+- Updated @push.rocks/smartchok ^1.0.34 → ^1.1.1
+- Updated @push.rocks/smartenv ^5.0.12 → ^5.0.13
+- Updated @push.rocks/smartfile ^11.2.3 → ^11.2.5
+- Updated @push.rocks/smarts3 ^2.2.5 → ^2.2.6
+- Updated @push.rocks/smartshell ^3.2.3 → ^3.2.4
+- Updated ws ^8.18.2 → ^8.18.3
+- Added .claude/settings.local.json for local Claude permissions and tooling (local-only configuration)
+
 ## 2025-07-24 - 2.3.2 - fix(tapbundle)
 Fix TypeScript IDE warning about tapTools parameter possibly being undefined
