What is Apereo CAS?

Apereo CAS opens an 8.1 line while 8.0 is still working through release candidates.

CAS is running a long release-candidate train. The 8.0.0 line reached RC6 in late June after RC4 and RC5 in spring, and 8.1.0-RC1 has now appeared in August. A 7.3.7.1 patch in June addressed a published OIDC vulnerability on the maintenance branch. The release entries themselves carry only navigation links and contributor credits, so feature detail is not visible here.

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.

Apereo CAS vs Tasmota: editorial side-by-side

Apereo CAS

2.5

Apereo CAS opens an 8.1 line while 8.0 is still working through release candidates.

◆ Current state

CAS is running a long release-candidate train. The 8.0.0 line reached RC6 in late June after RC4 and RC5 in spring, and 8.1.0-RC1 has now appeared in August. A 7.3.7.1 patch in June addressed a published OIDC vulnerability on the maintenance branch. The release entries themselves carry only navigation links and contributor credits, so feature detail is not visible here.

◆ Where it's heading

Two lines are moving at once, which suggests 8.0 is close enough to final that work has begun branching forward rather than that the RC train has stalled. The contributor lists stay small and consistent across releases - a handful of recurring maintainers - and security handling happens on the older supported branch, as it should.

◆ Prediction

An 8.0.0 final is the obvious next milestone given RC6 was three months ago and an 8.1 branch is already open. The release bodies do not describe features, so what it contains cannot be read from this feed.

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.
