v0.4.0

This release is a massive architectural rewrite with hundreds of internal changes. To make Relay more resilient and even faster, the server-side worker thread was removed in favor of serverless approach and per-connection invalidations with partially-shared in-memory caches. Additionally, unlicensed binaries will now run at full memory capacity for an hour before gracefully scaling down to the default limit.

• Added _pack() and _unpack() helpers
• Added pconnect(), close() and pclose()

Changed

• Updated relay.ini stub to match new architecture
• Added $connectionId parameter to flushMemory()
• socketKey() is now called endpointId()
• Switched to xxHash rather than dbj2 and fnv1a
• Use asynchronous DNS resolution

Removed

• Removed socketId() method
• libev dependency is no longer required
