DISCLAIMER: Apache Fluss (incubating) is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.

While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

Apache Fluss 0.9.1-incubating is a patch release on the 0.9 line containing bug fixes, Helm chart improvements, dependency upgrades, and documentation updates. It is fully compatible with 0.9.0 — no client or server changes are required to upgrade.
