What is Postman?

Postman is claiming the space between your app's tests and the APIs it actually depends on.

Two kinds of release sit side by side: steady spec and monitoring work — Smithy 2.0 in Spec Hub, more Monitor regions, version tags on changelogs — and the Application Inventory, which tracks applications, their external API dependencies, and the test coverage validating them.

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.

Postman is claiming the space between your app's tests and the APIs it actually depends on.

◆ Current state

Two kinds of release sit side by side: steady spec and monitoring work — Smithy 2.0 in Spec Hub, more Monitor regions, version tags on changelogs — and the Application Inventory, which tracks applications, their external API dependencies, and the test coverage validating them.

◆ Where it's heading

Postman is moving past the API client toward a dependency map of an organization's software. Wiring the Application Inventory into existing Playwright suites means the map populates from tests teams already run, which is how this kind of inventory avoids becoming a stale spreadsheet.

◆ Prediction

Expect the Application Inventory to grow beyond Playwright into other test runners and CI signals, since its usefulness scales with how much of the dependency graph it captures automatically.

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.
