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 Windmill?

Windmill gives its AI agents a test harness, the piece that lets them into production flows

Windmill is a developer platform for scripts, flows and internal apps, shipping weekly across three lanes. The AI lane is the busiest: sessions that build scripts and flows as reviewable drafts, a read-only plan mode that refuses writes until you approve, version history on session artifacts, and now evaluation for reusable agents. The runtime lane keeps absorbing data tooling — dbt projects run natively, BigQuery and Snowflake came out from behind the Enterprise licence. The workspace lane is consolidating deployment semantics around fork lineage.

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.

Windmill gives its AI agents a test harness, the piece that lets them into production flows

◆ Current state

Windmill is a developer platform for scripts, flows and internal apps, shipping weekly across three lanes. The AI lane is the busiest: sessions that build scripts and flows as reviewable drafts, a read-only plan mode that refuses writes until you approve, version history on session artifacts, and now evaluation for reusable agents. The runtime lane keeps absorbing data tooling — dbt projects run natively, BigQuery and Snowflake came out from behind the Enterprise licence. The workspace lane is consolidating deployment semantics around fork lineage.

◆ Where it's heading

The AI work has moved through a recognisable sequence: first let the assistant build things, then constrain what it may do without approval, then make its output reviewable and revertible, and now make agents measurable against a fixed set of cases. That is the arc of taking AI from a demo surface to something you are willing to put in a scheduled flow. In parallel, Windmill keeps pulling data-stack runtimes inside its own execution model rather than integrating with them, and keeps giving away runtimes that were previously licensed.

◆ Prediction

Evals are the obvious hook for regression gating, so expect them to be callable from a flow or CI rather than only from the agent card, and expect the eval run history to feed the same version-comparison surface the session artifacts already use.
