Changelog

Released versions of com.useceleris:celeris-client and celeris-server.

The artifacts are com.useceleris:celeris-client and com.useceleris:celeris-server on Maven Central. Celeris releases them together. Celeris tests each server version against one exact client version and pins it.

v1.0.0 — 2026-10-15

This is the first stable release of both artifacts, for Java 17 and later. celeris-server 1.0.0 pins celeris-client 1.0.0. The release contains:

Channels and segments over one WebSocket, publish/subscribe, presence, replay, and automatic recovery with jittered retries and fresh credentials for each attempt.
Payload helpers for text and JSON, plus PayloadCodec.of for your own format.
A server-side credential signer with least-privilege claims.

The client uses the JDK's own java.net.http WebSocket, so it has no runtime dependencies. Android lacks that client and is not supported.
