Cloudflare’s Post-Quantum GeoKey Manager Enters Closed Beta Without Attribute-Based Encryption
Cloudflare has moved a post-quantum rebuild of GeoKey Manager into closed beta, guarding geo-fenced keys with hybrid ML-KEM-768 and X25519 instead of the attribute-based encryption used since 2022.

LocalStack has opened its Azure emulator to a free public preview, running Azure services locally and accepting existing ARM, Bicep, and Terraform without rewrites. Its own documentation reports partial operation coverage per service and a consistent pattern: configuration is stored and returned, while enforcement of access restrictions, TLS, and network rules is not implemented.
