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 Parse Server?
One commit per release, and most of them are closing security holes in the Cloud Code and query paths.
Parse Server's feed is a stream of alpha prereleases — 9.10.0-alpha.6 through 9.10.1-alpha.6 in under three weeks — each containing exactly one bug fix, published automatically per merged commit. The security-relevant ones dominate: session creation that could delete another user's session, a beforeFind trigger context not isolated from prototype pollution, and GraphQL error messages disclosing pointer and relation target class names even with public introspection disabled, that last one carrying a published advisory identifier.

Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.
◆ 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.
Parse Server
5.0INFRA · APIS
One commit per release, and most of them are closing security holes in the Cloud Code and query paths.
◆ Current state
Parse Server's feed is a stream of alpha prereleases — 9.10.0-alpha.6 through 9.10.1-alpha.6 in under three weeks — each containing exactly one bug fix, published automatically per merged commit. The security-relevant ones dominate: session creation that could delete another user's session, a beforeFind trigger context not isolated from prototype pollution, and GraphQL error messages disclosing pointer and relation target class names even with public introspection disabled, that last one carrying a published advisory identifier.
◆ Where it's heading
The work is concentrated on trust boundaries in the parts of Parse Server that run user-supplied code or expose schema shape — Cloud Code triggers, validators, GraphQL introspection, session handling. Interleaved with it is ordinary supply-chain upkeep, with ws and follow-redirects bumped in their own releases. A MongoDB 8.3 compatibility fix for GeoPoint distance queries suggests the driver and database ends are being chased as well. Nothing in this window adds capability; it is all correctness and containment ahead of a stable cut.
◆ Prediction
The alpha numbering restarting at 9.10.1-alpha.1 indicates 9.10.0 was released, so expect the 9.10.1 alphas to continue accumulating single-fix releases until the patch is cut — with more Cloud Code trigger isolation fixes the likeliest content.
