# Changelog
|
||||
|
||||
## 2026-02-01 - 2.12.5 - fix(mail)
|
||||
migrate filesystem helpers to fsUtils, update DKIM and mail APIs, harden SMTP client, and bump dependencies
|
||||
|
||||
- Introduce plugins.fsUtils compatibility layer and replace usages of plugins.smartfile.* with plugins.fsUtils.* across storage, routing, deliverability, and paths to support newer smartfile behaviour
|
||||
- Update DKIM signing/verifying to new mailauth API: use signingDomain/selector/privateKey and read keys from dkimCreator before signing; adjust verifier fields to use signingDomain
|
||||
- Harden SMTP client CommandHandler: add MAX_BUFFER_SIZE, socket close/error handlers, robust cleanup, clear response buffer, and adjust command/data timeouts; reduce default SOCKET_TIMEOUT to 45s
|
||||
- Use SmartFileFactory for creating SmartFile attachments and update saving/loading to use fsUtils async/sync helpers
|
||||
- Switch test runners to export default tap.start(), relax some memory-test thresholds, and add test helper methods (recordAuthFailure, recordError)
|
||||
- Update package.json: simplify bundle script and bump multiple devDependencies/dependencies to compatible versions
|
||||
|
||||
## 2025-01-29 - 2.13.0 - feat(socket-handler)
|
||||
Implement socket-handler mode for DNS and email services, enabling direct socket passing from SmartProxy
