What is Authelia?

Authelia ships weekly OIDC patches as v4.39 works through a long conformance backlog

Authelia is in a steady patch release cycle for v4.39, shipping OIDC conformance fixes, proxy integration patches, and storage correctness fixes every few days. Recent releases address edge cases in consent flows (pre-configured consent saved twice, consent redirect status codes), JARM alg-none conformance, Envoy authz path handling, and SMTP IPv6 literal address support.

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.

Authelia ships weekly OIDC patches as v4.39 works through a long conformance backlog

◆ Current state

Authelia is in a steady patch release cycle for v4.39, shipping OIDC conformance fixes, proxy integration patches, and storage correctness fixes every few days. Recent releases address edge cases in consent flows (pre-configured consent saved twice, consent redirect status codes), JARM alg-none conformance, Envoy authz path handling, and SMTP IPv6 literal address support.

◆ Where it's heading

The high frequency of point releases reflects a long tail of OIDC conformance issues surfaced as more client libraries and proxy configurations hit edge cases in production. The v4.39.21 batch was notably large—over 30 fixes covering LDAP stale aliases, storage AAD/HKDF hardening, token regeneration semantics, and pre-compressed asset serving. This is a codebase being actively hardened rather than feature-extended.

◆ Prediction

A v4.40.0 feature release is the logical next milestone; the dense patch cadence in 4.39 typically precedes a feature window. Expect new OIDC profile features or expanded token management based on the storage and JWT work in recent patches.

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.
