-----------------------------------------
Summary: 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
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.
