> Bump Flink version to 1.20.4 in flink-kubernetes-operator
> ---------------------------------------------------------

> Key: FLINK-39838
> URL: https://issues.apache.org/jira/browse/FLINK-39838
> Project: Flink
> Issue Type: Improvement
> Components: Kubernetes Operator
> Reporter: Purushottam Sinha
> Assignee: Purushottam Sinha
> Priority: Minor
> Labels: pull-request-available
> Fix For: kubernetes-operator-1.16.0
>
>
> The operator currently builds against Flink 1.20.1 (released 2025-01-28;
> flink.version in the root pom.xml). The latest patch in the 1.20 line is
> 1.20.4 (released 2026-04-16).
> Bump flink.version 1.20.1 → 1.20.4 to pick up the bug and security fixes
> accumulated across three patch releases (1.20.2, 1.20.3, 1.20.4). As a patch
> bump within the same minor, it is source/binary compatible and low-risk.
> Note: flink.version is the version the operator builds against; runtime
> support for the wider Flink range (2.0/2.1/2.2) is covered separately by the
> CI version matrix, so this change does not affect which Flink versions the
> operator can deploy.
> Changes:
> - Update flink.version 1.20.1 → 1.20.4 in the root pom.xml.
> - Verify no other pinned Flink coordinates need aligning.
> Verification:
> - Full mvn clean install build passes.
> - CI passes, including the e2e version matrix (e2e jobs pull the flink:1.20.4
> image).
> Acceptance criteria:
> - Operator builds and all tests/CI pass against Flink 1.20.4.
