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 Raygun?

Raygun's public changelog stops in November 2024, mid-SDK-maintenance.

The crawled changelog runs from June 2022 to November 2024 and then stops. Its final entries are SDK upkeep across the .NET family: a memory-leak fix in Raygun4Net v8.2.1, a Serilog sink patch, a MAUI release candidate. Product-side work in the visible window is confined to Real User Monitoring CSV exports and a frequency chart on Crash Reporting search results, both from early 2024.

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.

Raygun's public changelog stops in November 2024, mid-SDK-maintenance.

◆ Current state

The crawled changelog runs from June 2022 to November 2024 and then stops. Its final entries are SDK upkeep across the .NET family: a memory-leak fix in Raygun4Net v8.2.1, a Serilog sink patch, a MAUI release candidate. Product-side work in the visible window is confined to Real User Monitoring CSV exports and a frequency chart on Crash Reporting search results, both from early 2024.

◆ Where it's heading

Across the window the pattern is client-library upkeep rather than platform direction: keeping .NET, MAUI and Serilog integrations current while sanding edges on Crash Reporting and RUM views. Raygun4Net v9.0.0 in February 2024 is the one structural move, dropping legacy framework support and shifting message delivery to a background queue. Whether that consolidation continued cannot be read from this feed.

◆ Prediction

No grounded prediction is available: the feed has been silent for roughly 21 months, so the current roadmap is invisible here. The open question is whether the changelog moved elsewhere rather than whether Raygun stopped shipping.
