What is Raygun?

Raygun's public changelog stops in November 2024, mid-SDK-maintenance.

The crawled changelog runs from June 2022 to November 2024 and then stops. Its final entries are SDK upkeep across the .NET family: a memory-leak fix in Raygun4Net v8.2.1, a Serilog sink patch, a MAUI release candidate. Product-side work in the visible window is confined to Real User Monitoring CSV exports and a frequency chart on Crash Reporting search results, both from early 2024.

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.

Raygun's public changelog stops in November 2024, mid-SDK-maintenance.

◆ Current state

The crawled changelog runs from June 2022 to November 2024 and then stops. Its final entries are SDK upkeep across the .NET family: a memory-leak fix in Raygun4Net v8.2.1, a Serilog sink patch, a MAUI release candidate. Product-side work in the visible window is confined to Real User Monitoring CSV exports and a frequency chart on Crash Reporting search results, both from early 2024.

◆ Where it's heading

Across the window the pattern is client-library upkeep rather than platform direction: keeping .NET, MAUI and Serilog integrations current while sanding edges on Crash Reporting and RUM views. Raygun4Net v9.0.0 in February 2024 is the one structural move, dropping legacy framework support and shifting message delivery to a background queue. Whether that consolidation continued cannot be read from this feed.

◆ Prediction

No grounded prediction is available: the feed has been silent for roughly 21 months, so the current roadmap is invisible here. The open question is whether the changelog moved elsewhere rather than whether Raygun stopped shipping.

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.
