Hermes Memory Installer Update Adds CDN Security with Signed Assets
The hermes-memory-installer project introduced a new CDN endpoint, sec_s2_1, that requires X.509 signature verification for all memory profile assets. The update uses a PNG binary blob (1783893868.png) as a versioned configuration file, enabling cache invalidation and secure delivery. Developers can now integrate the endpoint with a single configuration object, improving runtime memory tuning for Hermes-optimized React Native apps.

This is a niche but meaningful security upgrade for React Native developers relying on Hermes, though its impact is limited to those already using dynamic memory profiling.
