 # Changelog
 
+## 2026-02-06 - 3.3.0 - feat(mod_update)
+add self-update flow, package name parser, dynamic CLI version, and tests
+
+- Add a self-update check in mod_update to detect and optionally update @git.zone/tools (prompts the user or uses --yes).
+- Introduce PackageManagerUtil.parseYarnPackageName to correctly parse scoped and unscoped yarn package strings and use it when collecting installed packages.
+- Add comprehensive unit tests for PackageManagerUtil.isNewerVersion and parseYarnPackageName.
+- Use commitinfo.version for CLI reported version instead of a hardcoded value.
+- Remove automatic invocation of runCli() from ts/index.ts to avoid immediate execution on import.
+
+## 2026-02-05 - 3.2.0 - feat(update)
+enhance package manager detection, version reporting, and add verbose option
+
+- Add IPackageManagerInfo interface and detectPackageManager() to robustly detect npm/yarn/pnpm via 'which' and '--version' fallbacks
+- Make isAvailable() delegate to detectPackageManager() and return structured detection info
+- Add getPackageManagerVersion() to obtain current and latest versions (parses local --version and queries npm registry)
+- Update run() to support a verbose flag, show a package-manager status table, and collect detectedPMs with version/update status
+- Update CLI help and command handling to accept --verbose/-v and pass it through to mod_update.run()
+
+## 2026-02-03 - 3.1.3 - fix(mod_update)
+try private registry (verdaccio.lossless.digital) first when fetching package versions; fall back to public npm; handle unknown latest versions gracefully in output
+
+- getLatestVersion now attempts a direct API request to https://verdaccio.lossless.digital/<encoded-package> and parses dist-tags.latest
+- Falls back to npm view when the private registry request fails
+- Scoped package names are URL-encoded (replaces '/' with '%2f') before querying the private registry
+- Packages with no resolvable latest version are included with latestVersion set to 'unknown' and displayed as '? Version unknown'
+- needsUpdate is set to false when latest version is unknown
+
+## 2026-02-03 - 3.1.2 - fix(scripts)
+make test script output verbose by using --verbose instead of --web
+
+- package.json: change npm "test" script from "(tstest test/ --web)" to "(tstest test/ --verbose)" to enable verbose test output
+
+## 2026-02-03 - 3.1.1 - fix(tools)
+no changes detected
+
+- No files were modified in this diff
+- No code or documentation changes to include in a commit message
+
+## 2026-02-03 - 3.1.0 - feat(cli)
+add update command to check and update globally installed @git.zone packages
+
+- Adds a new mod_update module and PackageManagerUtil to detect installed @git.zone packages and fetch latest versions
+- Supports npm, yarn and pnpm: detection, listing, version comparison and executing updates
+- Interactive confirmation via @push.rocks/smartinteract with a -y flag to skip prompt
+- Uses @push.rocks/smartshell to run shell commands for listing and updating packages
+- Wires the new 'update' command into the CLI (tools.cli) and updates CLI version to 3.0.0
+- Adds CLI helper files (cli.child.js, adjusts cli.js and cli.ts.js) to run TypeScript CLI via tsrun/runPath
+- Updates package.json to include new dependencies and npmextra.json with release registries and @git.zone/cli metadata
+- Updates .gitignore to exclude local AI tool dirs (.claude, .serena)
+
 ## 2026-02-03 - 3.0.0 - BREAKING CHANGE(tools)
 replace install functionality with a minimal placeholder CLI; remove installer, logging, path utilities, and related assets
