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 tealeaves?
A leaf-temperature model that finished its job in 2020 and has stayed finished
tealeaves solves for leaf temperature from an energy balance, using explicit units to keep parameters consistent and modelling lower and upper leaf surfaces separately so sensible and latent heat loss are computed for each. The package reached its current form in 2020 across versions 1.0.2 to 1.0.5, which added direct or functional sky temperature, dplyr 1.0.0 compatibility, and fixes to a parameter-crossing bug that the new sky temperature function had introduced. The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.

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.

◆ Current state
tealeaves solves for leaf temperature from an energy balance, using explicit units to keep parameters consistent and modelling lower and upper leaf surfaces separately so sensible and latent heat loss are computed for each. The package reached its current form in 2020 across versions 1.0.2 to 1.0.5, which added direct or functional sky temperature, dplyr 1.0.0 compatibility, and fixes to a parameter-crossing bug that the new sky temperature function had introduced. The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.
◆ Where it's heading
This is finished scientific software. The arc runs from a 1.0.0 that already described the full model, through a usability decision in 1.0.1 to accept unitless values and assign units rather than demand them, to a 2020 cluster of compatibility and correctness work around publication. Nothing since has touched the model, and the 2022 release is pure paperwork. Its most instructive entry remains 1.0.5, where a new feature silently produced incorrect parameter crossing and the fix arrived with tests to pin the behaviour.
◆ Prediction
Expect nothing unless a dependency or CRAN check forces a release; on this record any such release will be documentation and packaging rather than a change to the energy balance.
