Dashy vs rush: at a glance
What is Dashy?
A release per merged PR, and right now nearly every one is a translation string.
Dashy is shipping a tagged release for essentially every merged pull request, producing ten versions in under three weeks. The current run is dominated by internationalization work: German and Traditional Chinese UI strings, plus a refactor that pulls hard-coded strings out of components so they can be translated at all. Dependabot accounts for the remainder.
What is rush?
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.

Dashy
6.3INFRA · APIS
A release per merged PR, and right now nearly every one is a translation string.
◆ Current state
Dashy is shipping a tagged release for essentially every merged pull request, producing ten versions in under three weeks. The current run is dominated by internationalization work: German and Traditional Chinese UI strings, plus a refactor that pulls hard-coded strings out of components so they can be translated at all. Dependabot accounts for the remainder.
◆ Where it's heading
The i18n push looks deliberate rather than incidental — extracting hard-coded strings is groundwork that only pays off if more locale contributions follow. Feature work has moved to the background; the last substantive changes in the visible window were OIDC post-logout redirect support and item sorting, both before this stretch. Cadence is high but the per-release payload is small.
◆ Prediction
Expect further locale contributions landing as individual patch releases while the string-extraction work continues to open up translatable surface area.
rush
2.5INFRA · APIS
Rush spent 2026 making distributed task ownership correct, starting with a breaking 1.0.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
