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 Gloo Gateway?

Gloo Gateway's October batch fixes proxies that silently kept stale endpoints.

Gloo Gateway still maintains 1.19, 1.20 and 1.21 in parallel and releases them in same-day batches. The 2026-10-21 batch fixes a bug where a placeholder EDS assignment carried the wrong cluster name, so a proxy received an update it could not match, kept its old endpoints and never recovered. Each line also moved to Go 1.26.10; 1.21 additionally upgraded kin-openapi.

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.

Gloo Gateway's October batch fixes proxies that silently kept stale endpoints.

◆ Current state

Gloo Gateway still maintains 1.19, 1.20 and 1.21 in parallel and releases them in same-day batches. The 2026-10-21 batch fixes a bug where a placeholder EDS assignment carried the wrong cluster name, so a proxy received an update it could not match, kept its old endpoints and never recovered. Each line also moved to Go 1.26.10; 1.21 additionally upgraded kin-openapi.

◆ Where it's heading

Releases remain maintenance: Go and Kubernetes bumps on a weekly rhythm, with an occasional real bug fix shipped to every line at once. The 1.18 line no longer appears in the October batches. No new features are visible.

◆ Prediction

Expect further same-day dependency batches across the three lines; the entries show no feature release coming.
