What's new in 6.1.2.43047

IN-CLIENT UPGRADE:
BREAKING CHANGES:
- Support for MacOS 12 will be discontinued in the next major release (6.2).
- Security hardening: Access-Control-Allow-Credentials is now false. Browser integrations using cookie-based authentication on cross-origin requests (including fetch with credentials: 'include', XHR.withCredentials = true and Axis requests with withCredentials: true) will stop working and must migrate to Authorization: Bearer <token>.
SECURITY UPDATES:
- Security hardening: Access-Control-Allow-Credentials is now false. Browser integrations using cookie-based authentication on cross-origin requests (including fetch with credentials: 'include', XHR.withCredentials = true and Axios requests with withCredentials: true) will stop working and must migrate to Authorization: Bearer <token>.
- Server now sends HSTS headers during the HTTP → HTTPS redirections. As a result, the initial connection is no longer vulnerable to SSL stripping and MITM attacks.
GENERAL IMPROVEMENTS:
- Server Monitoring graph colors improved.
- VCA edge build size is optimized - debug symbols are removed.
- Localization has been improved.
