Release v2.1.0

Added

• chronicle://host1:port,host2:port,... connection strings — the client now connects to any one of several configured hosts instead of only a single server. IPv6 hosts are supported via bracket notation.
• chronicle+srv:// connection strings, resolving the target host(s) via a DNS SRV lookup, re-resolved on every connect/reconnect so membership changes are picked up automatically. The DNS server to query can be overridden with the srvNameServer option.
• A loadBalancer connection string option selecting how one address is picked among several candidates: least-connections (the default — probes each candidate and picks the one with the fewest active connections), round-robin, or random.
• A skipTlsValidation connection string option to skip TLS certificate validation independently of disabling TLS entirely. Defaults to true, matching the client's previous behavior — set skipTlsValidation=false to require full certificate chain validation.
• Client connections now report the process id, machine name, and client type to the Chronicle kernel, improving connection diagnostics.

Changed

• The gRPC connection target now resolves any configured hostname correctly; previously only localhost was guaranteed to resolve.

Fixed

• Reactors and reducers no longer stop receiving events about a minute after startup. The client consumed the kernel's keep-alives but never answered them, so the kernel stopped counting it as connected and unsubscribed its observers — appending events kept working, which made the client look healthy.
• A lost connection is now detected and reconnected even when the stream stays open. The kernel does not close the keep-alive stream when it evicts a client, so a half-disconnected client previously stayed in that state until the application was restarted.
• A dropped connection no longer schedules two overlapping reconnects, and a connection that never came up no longer reports a disconnect to observers.

Changed

• Updated to Chronicle contracts 16.4.0.
