# Changelog
## 2026-02-10 - 2.3.2 - fix(tests)
remove large SMTP client test suites and update SmartFile API usage
- Deleted ~80 test files under test/suite/ (multiple smtpclient command, connection, edge-cases, email-composition, error-handling and performance test suites)
- Updated SmartFile usage in test/test.smartmail.ts: replaced plugins.smartfile.SmartFile.fromString(...) with plugins.smartfile.SmartFileFactory.nodeFs().fromString(...)
- Removes a large set of tests to reduce test surface / simplify test runtime
## 2026-02-10 - 2.3.1 - fix(npmextra)
update .gitignore and npmextra.json to add ignore patterns, registries, and module metadata
- .gitignore: expanded ignore list for artifacts, installs, caches, builds, AI dirs, and rust target path
- npmextra.json: added npmjs registry alongside internal Verdaccio registry for @git.zone/cli release settings
- npmextra.json: added projectType and module metadata (githost, gitscope, gitrepo, description, npmPackagename, license) for @git.zone/cli and added empty @ship.zone/szci entry
## 2026-02-10 - 2.3.0 - feat(mailer-smtp)
add in-process security pipeline for SMTP delivery (DKIM/SPF/DMARC, content scanning, IP reputation)
