What is ESPHome?

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

What is Kata Containers?

With the Rust runtime shipped, Kata turns to GPUs and slimmer packaging.

Kata Containers ships monthly, and 4.1.0 is the first release after the Rust runtime became the default. It is consolidation work: the static release tarball is split by runtime, the GPU extension is built without depending on the monolithic image, NVIDIA libraries are chiselled down from a filelist, and kata-deploy stops shipping virtiofsd when shared_fs is disabled. Dragonball merged its three network device managers into one, EROFS backing mode became configurable, and the CI matrix churned across s390x, arm64 and ppc64le.

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

◆ Current state

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

◆ Where it's heading

ESPHome is expanding in two directions simultaneously: broader hardware support (ESP32-P4, BK72xx BLE, new platform components) and more robust runtime behavior (RAMAllocator pattern, use-after-free fixes, better BLE-WiFi coexistence). The template climate component is the most user-visible addition — it brings custom HVAC logic into ESPHome's declarative model, reducing the need for external Home Assistant automations. Audio stack (i2s, resampler, mixer) reliability is also a consistent focus.

◆ Prediction

The 2026.10.0 cycle will likely continue the RAMAllocator pattern across remaining allocating code paths and add more ESP32-P4-specific features. Audio (voice assistants, speakers) will stay a top area given the ongoing i2s reliability work.

With the Rust runtime shipped, Kata turns to GPUs and slimmer packaging.

◆ Current state

Kata Containers ships monthly, and 4.1.0 is the first release after the Rust runtime became the default. It is consolidation work: the static release tarball is split by runtime, the GPU extension is built without depending on the monolithic image, NVIDIA libraries are chiselled down from a filelist, and kata-deploy stops shipping virtiofsd when shared_fs is disabled. Dragonball merged its three network device managers into one, EROFS backing mode became configurable, and the CI matrix churned across s390x, arm64 and ppc64le.

◆ Where it's heading

The rewrite arc has closed and an accelerator arc is opening in its place. Four separate changes in this release touch NVIDIA support — library chiselling, Fabric Manager topology, local CUDA repository support, and decoupling the GPU extension from the monolithic image — which is the shape of a project preparing for confidential GPU workloads rather than incidental hardware support. The packaging work points the same way: splitting tarballs by runtime and dropping unused components matters when the image is being pulled onto every node of a GPU cluster.

◆ Prediction

Expect the next releases to continue narrowing the shipped artifact and to deepen NVIDIA support toward attested GPU workloads, rather than to revisit the runtime itself.
