What is runc?

runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore

The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64. The changes with operational weight are that cpuAffinity and NUMA memoryPolicy no longer stop at 1024 CPUs or nodes, and that a container asking for a read-only rootfs without its own mount namespace is now refused. Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.

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.

runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore

◆ Current state

The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64. The changes with operational weight are that cpuAffinity and NUMA memoryPolicy no longer stop at 1024 CPUs or nodes, and that a container asking for a read-only rootfs without its own mount namespace is now refused. Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.

◆ Where it's heading

The project keeps converting silent behaviour into explicit behaviour. Read-only requests that were ignored now fail, a umask that was dropped is now honoured, and poststart hooks moved to conform to the runtime spec. The same maintainers are shrinking the surface underneath, dropping the deprecated API and the high-level cilium/ebpf path, which took roughly 7.5% off the 1.5.2 binary. Stricter behaviour plus a smaller dependency set is what a component under every container host would be expected to do between majors.

◆ Prediction

1.5.0's notes pointed to a 1.6.0 in late October 2026, and the feed so far shows only rc.1, so further release candidates or the final are the next entries to expect. The refused read-only configurations are the change most likely to surface as user reports during testing.

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.
