Deprecation of older TLS cipher suite support

Retired since May 2026 notable under review

Older TLS cipher suites are no longer supported for browser or API connections to Marketing Cloud Engagement as of the Summer '26 release; customers must use a modern TLS implementation such as TLS 1.3 with SHA-256/SHA-384 cipher suites.
