Jabsubcom New Info

Previous versions transmitted metadata in plain JSON, which became verbose at scale. The new release implements LPC using a variation of Zstandard (Zstd) with dictionary training specific to subscription patterns. Early benchmarks show a 40% reduction in network overhead for high-throughput topics.

The development team has published a preliminary roadmap for the 3.x series:

Cause: The new release requires server certificate with extended key usage for client auth.
Fix: Regenerate certificates with:

openssl req -x509 -newkey ec -pkeyopt ec_paramgen_curve:P-256 \

Legacy plain TCP on port 5555 is gone. All connections require TLS or WebSocket Secure (WSS). Previous versions transmitted metadata in plain JSON, which
