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 MISP?

MISP 2.5.46 delivers a 50× sightings query speedup and systematic SSRF closure — serious infrastructure work.

MISP is on a high-velocity cycle, shipping security audits and performance overhauls in parallel with the Overmind (Bootstrap 5) UI migration. Version 2.5.46 introduced a UrlEgressValidator providing a shared policy for all outbound URL requests and closing multiple SSRF vectors, while cutting sightings-retrieval query counts from 10,661 to 6 (a 50× reduction) and accelerating event report counts by 19–35×. The knowledge bases — misp-galaxy and misp-warninglists — are maintained as continuously updated datasets tracking ATT&CK changes and scanner infrastructure.

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.

MISP 2.5.46 delivers a 50× sightings query speedup and systematic SSRF closure — serious infrastructure work.

◆ Current state

MISP is on a high-velocity cycle, shipping security audits and performance overhauls in parallel with the Overmind (Bootstrap 5) UI migration. Version 2.5.46 introduced a UrlEgressValidator providing a shared policy for all outbound URL requests and closing multiple SSRF vectors, while cutting sightings-retrieval query counts from 10,661 to 6 (a 50× reduction) and accelerating event report counts by 19–35×. The knowledge bases — misp-galaxy and misp-warninglists — are maintained as continuously updated datasets tracking ATT&CK changes and scanner infrastructure.

◆ Where it's heading

Three parallel tracks define MISP's near-term direction: systematic security hardening (the 74-controller audit from 2.5.42 and the UrlEgressValidator framework in 2.5.46 signal structured review, not one-off patches), performance at scale (query-level optimizations targeting high-volume REST API and export workloads), and Overmind as the long-term UI replacement. Collection sync between instances, added in 2.5.43, opens a federation angle that matters for multi-tenant deployments and national MISP communities.

◆ Prediction

The next release will extend the UrlEgressValidator to remaining outbound paths not yet covered, and push more Overmind screens to production-ready status. Collection sync improvements are probable as early adopters stress-test cross-instance federation at scale.
