Symfony 8.2.0-BETA1 Hardens Security, Messaging

Symfony 8.2 is a pragmatic release focused on production correctness rather than flashy framework reinvention.

• –LDAP authentication now hashes presented passwords for unknown, disabled, or passwordless users, reducing timing-based account enumeration risks.
• –MongoDB Messenger gains keepalive support, improving reliability for long-running workers and queued workloads.
• –Applications without FrameworkBundle can generate configuration references and JSON schemas, making component-based Symfony setups easier to maintain.
• –Serializer and Messenger fixes target failure paths that previously caused silent property skips or prevented signed messages from being replayed.
• –Developers should test against the beta now, especially around security defaults, deprecations, and the PHP 8.4 requirement.
