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 HAProxy Kubernetes Ingress Controller?

Fourteen patches into 3.2, and ssl-passthrough is still where the bugs are.

The controller is deep in the 3.2 patch line, shipping roughly every two weeks with no new configuration surface since the series opened. Four of the last six releases touch ssl-passthrough: resolving its mode before rules are built, reconciling its backends, and now keeping allow and deny lists attached to the https frontend. The rest is Kubernetes-object correctness — EndpointSlice handling, ingress merge ordering, duplicated backend config snippets.

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.

H5.0

Fourteen patches into 3.2, and ssl-passthrough is still where the bugs are.

◆ Current state

The controller is deep in the 3.2 patch line, shipping roughly every two weeks with no new configuration surface since the series opened. Four of the last six releases touch ssl-passthrough: resolving its mode before rules are built, reconciling its backends, and now keeping allow and deny lists attached to the https frontend. The rest is Kubernetes-object correctness — EndpointSlice handling, ingress merge ordering, duplicated backend config snippets.

◆ Where it's heading

This is a stabilisation series, not a feature series. The recurring theme is that ssl-passthrough interacts badly with everything layered on top of it — access control, backend reconciliation, rule generation — and each release fixes one more intersection. Test coverage is now landing alongside the fixes rather than after them, which suggests the maintainers are treating the passthrough path as a known weak spot rather than a series of unrelated bugs.

◆ Prediction

Expect 3.2.x to continue at a two-week cadence with further ssl-passthrough intersections, and expect any new capability to wait for a 3.3 line rather than arrive in a patch.
