### ⚠️ Security: * Improves sender side handling of RETIRE_CONNECTION_ID frames. Without this an attacker could trigger an infinite loop by sending a specially-crafted set of frames that trigger a connection ID retirement ([CVE-2025-7054](https://www.cve.org/CVERecord?id=CVE-2025-7054)). ### Highlights: * Added [Config::set_initial_rtt()](https://docs.rs/quiche/0.24.5/quiche/struct.Config.html#method.set_initial_rtt) to allow control of a connection's initial RTT estimate. * Improvements and bug fixes to datagram packetization layer path MTU discovery (DPLPMTUD). * Other bug fixes and performance improvements.
