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 vcfR?

A genomics workhorse whose visible release feed stops dead in mid-2020.

vcfR reads, manipulates and visualises VCF files, the standard format for genomic variant calls, and bridges them into R population-genetics classes such as genind, genlight and DNAbin. The three entries available here all come from the first half of 2020 and stop there, so the feed shows the state of the package six years ago rather than today.

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.

0.0

A genomics workhorse whose visible release feed stops dead in mid-2020.

◆ Current state

vcfR reads, manipulates and visualises VCF files, the standard format for genomic variant calls, and bridges them into R population-genetics classes such as genind, genlight and DNAbin. The three entries available here all come from the first half of 2020 and stop there, so the feed shows the state of the package six years ago rather than today.

◆ Where it's heading

Within that window the direction is unmistakably consolidation, not growth. 1.9.0 pushed error handling down into the C++ layer that actually reads the VCF so failures surface earlier and shared files stop tripping a readability pre-check, tightened class checks, and added conversion options. The two releases after it exist only to keep pace with R 4.0.0 and dplyr 1.0.0. Any development after June 2020 is not visible in this feed, so the current trajectory cannot be read from it.

◆ Prediction

No prediction can be grounded in these entries — the feed has been silent for six years, which points at a stale or broken source rather than at a package that stopped.
