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 Coder?

Coder now patches three release lines at once, and the fixes keep landing on agent access.

Coder's feed shows patch releases on v2.29, v2.34 and v2.36 within three days, which means a v2.35 and a v2.36 mainline shipped that this feed never captured. The late-October fixes are permission work: new API keys stay within the caller's scopes, fetching external agent credentials now requires SSH permission, and read_skill_file reads are confined to the skill directory. Everything else is release-script and DERP client fixes.

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.

5.0

Coder now patches three release lines at once, and the fixes keep landing on agent access.

◆ Current state

Coder's feed shows patch releases on v2.29, v2.34 and v2.36 within three days, which means a v2.35 and a v2.36 mainline shipped that this feed never captured. The late-October fixes are permission work: new API keys stay within the caller's scopes, fetching external agent credentials now requires SSH permission, and read_skill_file reads are confined to the skill directory. Everything else is release-script and DERP client fixes.

◆ Where it's heading

The security surface is moving to the AI agent features. Two of the three substantive fixes this round concern what an agent can read or which credentials it can obtain, following the June hardening drop on OIDC linking and token theft. The multi-branch backporting continues, so enterprise customers on older lines like 2.29 still get the same permission fixes as the mainline.

◆ Prediction

Expect more permission checks around agent credentials and skills as those features get exercised; the feature releases themselves are not visible in this feed, so their direction is unclear from these entries.
