Alginte 0.7.0 Beta

Released 2026-07-31.

Alginte is in beta (0.x): configuration keys, the topology export format, and APIs may change between releases; breaking changes are called out in release notes with migration guidance.

Streams that fail honestly

Two failure paths in the Streams builder that used to be silent are now explicit. Deploying against a source topic that doesn't exist — unrecoverable in Kafka Streams — is blocked at Submit with a message naming the missing topic. And a source topic deleted after deploy now shows the stream as ERROR instead of displaying REBALANCING indefinitely while the real failure sat in the server log. Details: Deploy & manage. Topology-validation errors across the builder also now return proper 400s with readable messages instead of bare 500s.

Messages that count exactly — and explain themselves

Three subtle counting bugs in the message browser are fixed: a fetch could exceed the requested count when the broker split its response across polls; the Offset ≤ seek reported a total one below the rows it returned; and the per-partition split could overshoot the request by a few records. A request for N records now returns exactly what it says.

And when a fetch on a compacted topic legitimately returns fewer records than requested — offset ranges on compacted topics contain gaps — the UI now says so with an explanatory note instead of leaving the short result unexplained. Background: the Messages guide.

Troubleshooting guide

The docs gained a symptom-first Troubleshooting page: startup fail-fast causes, missing menu areas, short fetches, stream states, login errors, and port collisions — each with the why and the fix.
