Tailscale Unveils Grants: Next-Gen Access Controls

Tailscale announces the general availability of Grants, its next-generation access control system. Grants unify network and application permissions into a single, simpler syntax, improving upon the existing ACLs. It simplifies policy writing, adds features like embedding Tailscale directly into applications via the tsnet library for identity-based authorization and custom application capabilities, and introduces a `via` field for granular traffic routing. Crucially, Tailscale will continue supporting the older ACL syntax indefinitely, allowing for incremental migration.
