This is a patch upgrade for Netty, primarily focused on security and bug fixes. While patch releases are typically safe, this version contains fixes that could alter application behavior under specific circumstances.

Key Changes:

• Security Fixes: This version addresses numerous CVEs, including several within the netty-handler and related modules, such as fixes for OCSP validation and TLS hostname verification.
• Behavioral Fix: A notable change is a fix to the FlowControlHandler's autoRead behavior. Applications that were inadvertently relying on the previous incorrect behavior may be impacted and should be re-verified.
• Bug Fixes: The release also includes fixes for state handling in IdleStateHandler and resolves various memory leaks in other modules like HTTP/2.

Recommendation:
Due to the bug fix in FlowControlHandler which could change data flow, this upgrade is rated as medium risk. It is recommended to test your application's data flow and backpressure handling after upgrading.
