What is Cursor?
Cursor's agents stop waiting to be asked - they subscribe, and they hold a goal until it's done.
Cursor has spent two months moving agents out of the editor: cloud agents on iPhone and iPad, in Slack, on schedules, a team marketplace, a router picking the model per request, and Origin hosting repos and pull requests inside the product. This release changes how those agents are started. Cloud agents can subscribe to an event source - a PR, a Slack thread, a schedule - and wake when something happens, and /goal gives one a long-lived objective it works toward until complete. Subagents now get their own virtual machines with isolated project copies.
What is sdcHierarchies?
Hierarchy tooling for statistical disclosure control keeps trading R for Rcpp.
sdcHierarchies builds and manipulates the nested code hierarchies that statistical disclosure control depends on. Its release history is dominated by one theme: moving tree work into C++ and reporting the speedup. The March 2026 release adds hier_create_ids() for mapping microdata onto hierarchy levels by integer index, and extends hier_grid() with contributing-cell aggregation.

◆ Current state
Cursor has spent two months moving agents out of the editor: cloud agents on iPhone and iPad, in Slack, on schedules, a team marketplace, a router picking the model per request, and Origin hosting repos and pull requests inside the product. This release changes how those agents are started. Cloud agents can subscribe to an event source - a PR, a Slack thread, a schedule - and wake when something happens, and /goal gives one a long-lived objective it works toward until complete. Subagents now get their own virtual machines with isolated project copies.
◆ Where it's heading
The through-line has been removing external dependencies and wait states; this release removes the human from the trigger. Agents that Cursor created now subscribe to their own pull requests and drive them to completion, fixing CI and answering bot comments unprompted. Isolated per-subagent VMs are what make that safe to parallelize - swarms can work without colliding - and steering lets a person redirect a running agent at the next tool call rather than interrupting it. Cursor is building the always-on case rather than the faster-autocomplete one.
◆ Prediction
With subscriptions limited to cloud agents for now, the obvious next step is bringing event-triggered runs to local agents, along with the controls an always-on fleet needs - spend limits, approval gates, and a way to review what ran while nobody was watching.
sdcHierarchies
0.0INFRA · APIS
Hierarchy tooling for statistical disclosure control keeps trading R for Rcpp.
◆ Current state
sdcHierarchies builds and manipulates the nested code hierarchies that statistical disclosure control depends on. Its release history is dominated by one theme: moving tree work into C++ and reporting the speedup. The March 2026 release adds hier_create_ids() for mapping microdata onto hierarchy levels by integer index, and extends hier_grid() with contributing-cell aggregation.
◆ Where it's heading
Four of the last five releases are performance releases, and each names the specific function that got faster: hier_convert(), then hier_codes(), then the core tree traversal itself. The direction is toward handling hierarchies large enough that the R-level implementation stopped being viable, with the new integer-indexed ID mapping pointing the same way. Feature work rides along with the optimisation rather than driving it.
◆ Prediction
Expect the remaining R-level tree operations to follow hier_convert() and hier_codes() into Rcpp, and the new hier_grid() arguments to accumulate defaults as the aggregation path gets exercised.
