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 svrep?
Steadily absorbing every replicate-weight method the survey literature has to offer
svrep is a broad implementation of replication-based variance estimation for complex surveys, covering the generalized bootstrap, Fay's generalized replication, successive difference replication and the random-groups jackknife. The last two years added methods quickly: the Antal-Tille doubled half bootstrap, the Beaumont-Emond and kernel-based BOSB variance estimators, and optional torch-backed computation of replicate weights. Version 0.9.0 tightened the package boundary, promoting 'survey' from Imports to Depends and deleting the long-deprecated rescale_reps().

◆ 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.

Steadily absorbing every replicate-weight method the survey literature has to offer
◆ Current state
svrep is a broad implementation of replication-based variance estimation for complex surveys, covering the generalized bootstrap, Fay's generalized replication, successive difference replication and the random-groups jackknife. The last two years added methods quickly: the Antal-Tille doubled half bootstrap, the Beaumont-Emond and kernel-based BOSB variance estimators, and optional torch-backed computation of replicate weights. Version 0.9.0 tightened the package boundary, promoting 'survey' from Imports to Depends and deleting the long-deprecated rescale_reps().
◆ Where it's heading
The recent arc is consolidation rather than expansion. 0.9.0 removed a deprecated function, added accessors and refactored for memory, while 0.9.1 exists only to answer a Journal of Statistical Software review. That submission explains the shape of the changelog: the API is being frozen and documented rather than extended. Method coverage is broad enough that additions are now gap-fills for particular sampling designs.
◆ Prediction
Expect the next releases to track the JSS review through to publication with documentation and output-structure tidying, and any new estimator to arrive only when an issue or reviewer asks for a specific design.
