Incubator PMC report for June 2026

The Apache Incubator is the entry path into the ASF for projects and codebases wishing to become part of the Foundation's efforts.

There are currently 28 podlings under incubation. In May, the Incubator made five releases, and some release votes are currently underway. There were one addition and no removals to IPMC membership.

Mailing list discussion focused primarily on release voting activity and two graduation discussions: an active discussion on graduating Apache Fluss, and the graduation discussion and vote for Apache Livy, which passed.

There was also substantial mentor and release-policy discussion during the month, covering a potential issue with GitHub releases, use of Docker Hub images, PyPI packages, and whether a dependencies file is required for non-bundled dependencies in source releases, and Incubator graduation requirements.

There was also continued discussion of MCP-based tooling for Incubator insights and ASF policy questions.

Baremaps was retired by IPMC vote in March 2026. Some post-retirement cleanup is still outstanding.

OpenServerless has been incubating for about two years and has not yet made an ASF release. The podling has responded to the IPMC's concerns. It reports continuous development across its subrepositories, has started adding committers who contributed useful work, and has begun moving toward a release. Separately, much of the podling's discussion has taken place on Discord rather than on the public dev list, and the podling has been asked to move project and technical discussion to the public list.

OzHera has not made an ASF release in over a year despite ongoing development. The project has been asked to outline the current status of release preparation, what is blocking the next release, and to address low mentor engagement across recent reporting periods. They did not respond.

Caldera engagement has improved since the concerns raised last cycle. The project is now active on its dev list with healthy development activity.

Casbin discussion has begun moving onto the dev list.

PouchDB has yet to correct the redirection of the legacy pouchdb.com site.

Toree has been incubating since December 2015. The project is on a new release candidate, but the going is slow.

The IPMC continues to monitor long-running podlings and will follow up on any community concerns as needed.

Caldera

Caldera provides a modular platform for modeling, scripting, and executing adversary behavior. It allows users to construct emulation plans, provides agents for communicating with the command and control server, and enables users to evaluate security detections in a structured, scalable, and repeatable way. With the use of plug- ins and community-contributed features, Caldera supports a range of use cases including adversary emulation, purple teaming, detection engineering, and continuous security validation. Using Caldera, defenders can emulate known threat actor behavior and perform other red team activity to evaluate their organization’s defensive capabilities, test analytics, and find detection gaps. As a modular tool based on the MITRE ATT&CK framework, Caldera is designed to be extensible, intelligence-driven, and automation-friendly.

Caldera has been incubating since 2025-12-19.
