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 vimp?
Algorithm-agnostic variable importance, settled since 2022 and now answering CRAN checks
vimp performs inference on variable importance measures that do not depend on the fitting algorithm, using sample-splitting so tests stay valid under the zero-importance null. The statistical design settled in 2022: predictiveness measures gained their own S3 class, point estimation was decoupled from inference through the final_point_estimate argument, and method and family moved to the outer functions so binary outcomes work. The two 2025 releases are a CRAN documentation fix and an edge-case correction for cutoff-based measures when every prediction is the same value.

Cursor's agents stop waiting to be asked - they subscribe, and they hold a goal until it's done.
◆ 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.

Algorithm-agnostic variable importance, settled since 2022 and now answering CRAN checks
◆ Current state
vimp performs inference on variable importance measures that do not depend on the fitting algorithm, using sample-splitting so tests stay valid under the zero-importance null. The statistical design settled in 2022: predictiveness measures gained their own S3 class, point estimation was decoupled from inference through the final_point_estimate argument, and method and family moved to the outer functions so binary outcomes work. The two 2025 releases are a CRAN documentation fix and an edge-case correction for cutoff-based measures when every prediction is the same value.
◆ Where it's heading
Substantive development ended in 2022, followed by one narrow addition — a cluster bootstrap for correlated data in 2023 — and two housekeeping releases. What remains visible are careful decisions about the boundary between estimation and inference, including the warning that a Wald interval will not be centred on the point estimate when the full-data or averaged option is used. The maintainer is keeping the package correct and installable rather than extending it.
◆ Prediction
Expect maintenance releases keyed to CRAN check changes; new predictiveness measures are the plausible extension, since the S3 class added in 2.3.0 was introduced specifically to make adding them simpler.
