What is Windmill?

Windmill collapsed its deployment model, opened two paid runtimes, and let an agent build the workspace.

Ten days in late July carried three unrelated structural changes. The workspace-level deploy target was removed entirely — a workspace now deploys into its lineage parent, so the setting can no longer disagree with itself, and job tags resolve $workspace against the nearest provisioned ancestor. BigQuery and Snowflake moved out from behind the Enterprise license into community builds. AI sessions entered beta enabled by default, tying a chat to a workspace or fork with a live preview, producing scripts, flows and apps as drafts reviewed in a diff drawer. The surrounding releases are AI chat refinements: file attachments read on demand, web search sources shown with the query.

What is Jackett?

A daily-shipping indexer proxy whose entire product is a scraper definition file that never stops rotting.

Jackett ships a tagged release essentially every day, and every one of them is the same shape: tracker selectors updated, domains bumped, categories added, dead sites removed. The release notes are auto-generated commit lists with no prose. The C# application itself is stable; what changes is the YAML definition corpus that keeps a few hundred torrent trackers reachable through a single Torznab endpoint.

Windmill collapsed its deployment model, opened two paid runtimes, and let an agent build the workspace.

◆ Current state

Ten days in late July carried three unrelated structural changes. The workspace-level deploy target was removed entirely — a workspace now deploys into its lineage parent, so the setting can no longer disagree with itself, and job tags resolve $workspace against the nearest provisioned ancestor. BigQuery and Snowflake moved out from behind the Enterprise license into community builds. AI sessions entered beta enabled by default, tying a chat to a workspace or fork with a live preview, producing scripts, flows and apps as drafts reviewed in a diff drawer. The surrounding releases are AI chat refinements: file attachments read on demand, web search sources shown with the query.

◆ Where it's heading

All three moves push in the same direction — making the workspace itself the unit an agent can safely operate on. A single derived deployment target removes the ambiguity an automated change would otherwise have to resolve; the diff drawer and Compare & Deploy give a review gate for machine-authored artifacts; parallel sessions assume more changes in flight than a person would make by hand. Windmill is building the promotion path first and the agent second, which is the opposite order from most tools that added a chat and then discovered they needed review.

◆ Prediction

Expect AI sessions to leave beta with the diff and deploy path as the safety story, and more runtimes to follow BigQuery and Snowflake out of the Enterprise tier — Oracle DB and MS SQL are the two named as still gated. The compressed release timing suggests these landed as one planned batch rather than a new sustained pace.

5.0

A daily-shipping indexer proxy whose entire product is a scraper definition file that never stops rotting.

◆ Current state

Jackett ships a tagged release essentially every day, and every one of them is the same shape: tracker selectors updated, domains bumped, categories added, dead sites removed. The release notes are auto-generated commit lists with no prose. The C# application itself is stable; what changes is the YAML definition corpus that keeps a few hundred torrent trackers reachable through a single Torznab endpoint.

◆ Where it's heading

This is maintenance-as-product, and the cadence is a symptom rather than a sign of momentum: trackers move domains, add anti-bot checks, and change markup, so the definitions decay continuously and the fix rate has to match. The visible trend across these releases is attrition — torr9, rockbox, rain, runtheframes, torrentleech-pl and elitetorrent-wf all removed in a single fortnight — partially offset by category expansion on the trackers that survive.

◆ Prediction

Expect the daily definition-churn cadence to continue unchanged, with the removal list growing faster than the addition list. Nothing in these entries indicates work on the application core.
