Cursor is industrializing cloud agents — routed models, prebuilt environments, every surface.
Cursor's last two months are almost entirely about cloud agents rather than the editor. Agents now launch from iOS, iPad, and Slack, run in isolated VMs, and boot from environments Cursor rebuilds in the background. Auto mode became Cursor Router, which dispatches each request to a frontier or price-efficient model and bills at the routed model's rate. Team plumbing matured alongside it: marketplaces, Team MCPs, plugins, and automations.
Rush spent 2026 making distributed task ownership correct, starting with a breaking 1.0.
rush is the Redis-backed distributed computing backend behind mlr3's parallel tuning: workers pull tasks, push results and are tracked through heartbeats. Since 1.0.0 in March 2026 it has shipped five releases in four months, almost all correcting how tasks and workers are owned and identified under failure. The most recent lets each worker start in its own mirai call so it can spawn local daemons.

The direction is making the agent rather than the editor the unit of work, then removing every source of latency and friction around it. Environment setup went from a manual step to a reusable snapshot to a continuously rebuilt warm pool; model selection went from a picker to a router with admin controls; surfaces went from desktop to phone, tablet, and chat. Nearly every release pairs the user-facing feature with an admin or team control, which points at enterprise buyers as the audience being served.
The next moves most likely target cloud agent throughput and spend controls — finer routing or more environment reuse — rather than another client surface, since mobile and Slack have each had two releases already and the newest work concentrates on what happens before an agent's first token.

The most recent lets each worker start in its own mirai call so it can spawn local daemons.
The through-line is moving responsibility from the controller to the worker. 1.0.0 rewrote the task lifecycle and dropped the seed mechanism; 1.2.0 moved fail_tasks(), finish_tasks(), pop_task() and push_running_tasks() from Rush onto RushWorker so only the worker that ran a task can mark it done, and gave worker ids random suffixes so they cannot collide. 1.1.0 had already removed phantom failed tasks when a worker crashes between evaluations.
With ownership and identity settled, the remaining pressure points are heartbeat and lost-worker detection; expect the next releases to tighten failure recovery rather than add API surface.
