What is Cobbler?

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

What is Mergify?

Mergify's merge queue now hunts the breaking PR by rerunning failed tests first

Mergify shipped more than a dozen changes in the last week of October. On the merge queue, failed batches now run the failing tests first in each split, stacked PRs enter the queue together, scope capacities work with Bazel, Pants and Turborepo scopes and patterns, and batch merge commits name the PRs they land. Test Engine gained Minitest, Jest and Mocha plugins and a setup path driven by a coding agent. Jinja2 expressions in configuration stopped being evaluated on October 31.

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

◆ Current state

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

◆ Where it's heading

The branch is still gaining features aimed at enterprise data centres rather than winding down: new installer ecosystems in August, directory-backed single sign-on now. Authentication has been a recurring concern since the CVE-2024-47533 admin-API bypass. Releases continue to arrive as rollups from main.

◆ Prediction

Expect further 3.3.x rollups; whether the main line cuts a 3.4 is not visible from these entries.

Mergify's merge queue now hunts the breaking PR by rerunning failed tests first

◆ Current state

Mergify shipped more than a dozen changes in the last week of October. On the merge queue, failed batches now run the failing tests first in each split, stacked PRs enter the queue together, scope capacities work with Bazel, Pants and Turborepo scopes and patterns, and batch merge commits name the PRs they land. Test Engine gained Minitest, Jest and Mocha plugins and a setup path driven by a coding agent. Jinja2 expressions in configuration stopped being evaluated on October 31.

◆ Where it's heading

Mergify is tying its merge queue to test data: Test Engine knows which tests fail, and the queue uses that to bisect faster with less CI. Monorepo build tools and stacked PRs are now first-class queue inputs.

◆ Prediction

More queue behavior driven by Test Engine results is likely, given that Fail First and the new test plugins shipped the same week.
