New features in NGINX Plus R23:
- gRPC health checks – Actively testing that a gRPC service can handle requests before sending them significantly boosts reliability.
- Unprivileged installation support – NGINX Plus can now be installed by, and upgraded as, an unprivileged (non‑root) user. This fully supported solution aligns with the growing trend toward zero‑trust security models.
- OpenID Connect PKCE support – NGINX Plus R23 implements the Proof Key for Code Exchange (PKCE) extension to the OpenID Connect Authorization Code flow. PKCE prevents several types of attack and enables secure OAuth exchanges with public clients.
NGINX Plus R23 supports the gRPC health checking protocol. It enables to accurately test whether backend gRPC servers are able to handle new requests.
