What is Ably?
Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.
The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.
What is ESPHome?
A monthly release train where the substance hides in the patch releases
ESPHome runs a strict calendar train — a 2026.7.0 feature release preceded by four betas, then a steady run of .1/.2/.3 patches. The patch releases carry most of the visible work: per-component fixes across BLE, WiFi, Ethernet, display and audio drivers, plus repeated bumps of the bundled esphome-device-builder. The 2026.7.0 entry itself links out to a changelog rather than listing anything.

◆ Current state
The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.
◆ Where it's heading
The pattern is a realtime messaging company treating agent runs as the thing its network transports. Each AI Transport release closes a gap that would otherwise force developers to build around the channel — history reconciliation, crash recovery, changing direction mid-response, and now speaking a specific model provider's wire format. The LiveObjects work runs on a slower track and points the same way: path-based subscriptions that survive structural change are aimed at the fast-mutating state agents and collaborative apps produce.
◆ Prediction
Expect the codec pattern to extend to other model provider APIs beyond OpenAI Responses, and the LiveObjects path-based API to keep propagating across the remaining SDK languages after Java.

A monthly release train where the substance hides in the patch releases
◆ Current state
ESPHome runs a strict calendar train — a 2026.7.0 feature release preceded by four betas, then a steady run of .1/.2/.3 patches. The patch releases carry most of the visible work: per-component fixes across BLE, WiFi, Ethernet, display and audio drivers, plus repeated bumps of the bundled esphome-device-builder. The 2026.7.0 entry itself links out to a changelog rather than listing anything.
◆ Where it's heading
Two threads run through the window. The first is multi-platform build hardening — honoring compile process limits in native ESP-IDF builds, widening the app source glob to .cc/.cxx/.c++, fixing submodule cloning on the esp-idf toolchain, and Zephyr/nRF52 SDK discovery. The second is memory and input safety: escaping SSIDs in captive portal JSON, locking scan results shared with the web task, dropping oversized ESP-NOW frames, and fixing a use-after-return in the IDF HTTP backend.
◆ Prediction
The cadence points to a 2026.8.0 beta series opening within weeks, with the bundled device-builder continuing to move on its own faster track. What lands in that feature release is not visible from these entries, since the feature-release notes are published off-site.
