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 Jaeger?
Jaeger folds its MCP server into the query service and drops Elasticsearch 6
Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.

◆ 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.

Jaeger folds its MCP server into the query service and drops Elasticsearch 6
◆ Current state
Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.
◆ Where it's heading
Jaeger is treating machine consumption of traces as a first-class query path rather than an add-on. Merging jaegermcp into jaegerquery means the MCP surface ships wherever query ships, and trace summaries give both the UI and any agent a cheap way to scan results before pulling full traces. On storage, the direction is fewer supported backends maintained better, with ClickHouse steadily gaining parity.
◆ Prediction
Expect the trace-summaries path to become the default for search across storage backends, and further ClickHouse feature work as the Elasticsearch surface is trimmed rather than extended.
