# 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.
