# Kiloparsec 0.8.0

Stable release of authenticated protocol 2 and the TypeScript/WASM client source.

- Authenticate RPC kind, correlation and priority; confirm accepted client identity with an encrypted server-finished response.
- Discard duplicate and stale authenticated packets without closing healthy sessions or consuming pending response waiters.
- Bound priority overtaking with the nonce-aware outgoing queue. Serialize encryption and queue admission, retaining progress for older low-priority messages.
- Preserve sessions after local send failures and use a bounded bitmap for replay tracking.
- Honor application initialization rejection on both peers, including subclasses of security and connection-break exceptions.

Protocol 2 requires coordinated peer upgrades from protocol 1. The fixes preserve the protocol-2 wire encoding. The TypeScript client retains synchronous FIFO WebSocket sending; its private npm package is distributed as source in this release.

Validation: 64 JVM tests, 47 Kotlin/JS Node tests, 38 TypeScript unit tests and live TypeScript/JVM interoperability passed. Real loopback TCP/UDP tests cover bidirectional calls and UDP duplication/reordering. All 13 Maven publications built; a separate consumer using staged release artifacts passed interoperability without source substitution. Browser, Android and Apple runtimes were not qualified in this release run.
