ngtcp2 1.18.0, nghttp3 1.13.1 rpms released and added to all supported platforms.
All the libraries stack built with OpenSSL 3.5.4, including ngtcp2 (quic client name changed from qtlsclient to osslclient).
Delivery of nghttp3 1.13.0 was cancelled because the release was broken for ARM due to bug #414 (reported and fixed).
