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 Tasmota?

Tasmota 16 adds optional MQTT 5.0 and DALI-2 commissioning for lighting control.

v16.0.0 Theo landed in mid-October. It adds optional MQTT 5.0 focused on request and response, initial ESP32-S31 and ESP32-C61 support, and DALI-2 device commissioning, input events and push-button bindings. HVAC work is also heavy, with a MiELHVAC web panel, Modbus RTU slave and Home Assistant discovery.

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.

Tasmota 16 adds optional MQTT 5.0 and DALI-2 commissioning for lighting control.

◆ Current state

v16.0.0 Theo landed in mid-October. It adds optional MQTT 5.0 focused on request and response, initial ESP32-S31 and ESP32-C61 support, and DALI-2 device commissioning, input events and push-button bindings. HVAC work is also heavy, with a MiELHVAC web panel, Modbus RTU slave and Home Assistant discovery.

◆ Where it's heading

The major number doesn't change the release's character: breadth remains the product. Two threads stand out from the driver list. Building-automation protocols are getting deeper support, with DALI-2, Modbus and OpenTherm's second heating circuit, and MQTT 5.0 updates the core messaging layer for the first time in these entries.

◆ Prediction

Expect the next release in about two months with further DALI-2 and Berry work, and fuller ESP32-S31 support, since the current support is labeled initial.
