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 Dub?
Dub adds AI application screening as its partner program controls keep getting finer.
Dub's run since July is almost entirely Dub Partners. Programs can now auto-reject applicants against plain-language criteria, set rewards per partner or per link, pay retainer-style fixed amounts, and let existing partners apply to switch groups. Bounties and email campaigns gained tag scoping and combined conditions, while the link product got one-click DNS setup for Vercel and Cloudflare.
Cobbler vs Dub: editorial side-by-side
Cobbler
0.0INFRA · APIS
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.
Dub
5.0INFRA · APIS
Dub adds AI application screening as its partner program controls keep getting finer.
◆ Current state
Dub's run since July is almost entirely Dub Partners. Programs can now auto-reject applicants against plain-language criteria, set rewards per partner or per link, pay retainer-style fixed amounts, and let existing partners apply to switch groups. Bounties and email campaigns gained tag scoping and combined conditions, while the link product got one-click DNS setup for Vercel and Cloudflare.
◆ Where it's heading
The partner product is moving from commission setup to program operations. Retainers and link-level rewards widen what can be paid for, and AI now appears in two administrative jobs, reward building and application screening. Each release reduces a manual step for program operators.
◆ Prediction
Expect more AI help in program administration, since reward building and screening shipped within two months of each other. Further reward primitives are also likely given the pace since July.
