**Changed**
- Insert GREASE in KX, TLS Version and Ciphers.
- Backport "Only buffer up to 512 KiB of pending CRYPTO frames" https://github.com/aiortc/aioquic/commit/174a2ebbe928686ef9663acc663b3ac06c2d56f2

**Fixed**
- Certificate fingerprint matching.
- Backport upstream urllib3/urllib33434: util/ssl: make code (certificate fingerprint matching) resilient to missing hash functions.
