What is Drone CI?
Drone now ships as Harness Open Source, and its releases are mostly code-hosting features.
The feed tracked for Drone CI is the Harness Open Source repository, which absorbed Drone. Its two visible releases are about Git hosting, not pipelines: v3.2.0 added Git LFS, default reviewers through branch rules, PR retargeting and a revert option, and v3.3.0 in August 2025 added tag rules, a PR dashboard with favorite repositories, and a fix for a Git LFS upload path-traversal issue.
What is Ably?
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.

Drone now ships as Harness Open Source, and its releases are mostly code-hosting features.
◆ Current state
The feed tracked for Drone CI is the Harness Open Source repository, which absorbed Drone. Its two visible releases are about Git hosting, not pipelines: v3.2.0 added Git LFS, default reviewers through branch rules, PR retargeting and a revert option, and v3.3.0 in August 2025 added tag rules, a PR dashboard with favorite repositories, and a fix for a Git LFS upload path-traversal issue.
◆ Where it's heading
Drone's identity is being folded into a broader Harness platform that combines code hosting, review and CI. Recent work brings branch- and tag-protection rules and review workflows up to GitHub and GitLab standards. Nothing in these entries concerns Drone's pipeline engine directly.
◆ Prediction
With only two releases, three months apart, visible, the cadence is unclear. If it continues, expect more repository governance and PR workflow features rather than CI changes.
Ably
7.5INFRA · APIS
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
◆ Current state
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
◆ Where it's heading
The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.
◆ Prediction
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
