Dapr v1.16.15

This maintenance release addresses a critical issue where the Sentry control plane component would fail to start when using specific cryptographic key types (Ed25519 or RSA). This fix is particularly vital for operators performing version downgrades or those using custom security configurations, ensuring continuous identity issuance and mTLS certificate rotation for microservices.

Fix Sentry crash with Ed25519 and RSA issuer keys — This fix prevents the Dapr Sentry service from crash-looping when encountering modern encryption keys. Without this, your microservices would eventually lose the ability to communicate securely via mTLS as certificates expire or new sidecars are spun up, especially if you have ever experimented with newer Dapr versions or manually rotated your cluster keys.
