What is CRediTas?

A CRediT author-statement generator that renamed itself, then went quiet for two years.

CRediTas turns a contributor-roles table into a CRediT Author Statement for a paper. The 0.2.0 release in April 2023 did the heavy lifting — package rename, a full object_verb() API rename, and output that drops straight into R Markdown or Quarto. The 0.3.0 release in August 2025 is the only activity since and carries no changelog text beyond a pointer to NEWS.md.

What is mirai?

mirai removed its dispatcher process and added memory backpressure to the queue.

The async evaluation framework releases roughly monthly and moves fast at the architecture level. In 2.7.0 the dispatcher stopped being a separate process and became a thread, after its loop had already been rewritten in C inside nanonext one release earlier. The same release added an opt-in memory budget for queued task payloads and try_mirai(), which returns NULL immediately rather than blocking when that budget is exhausted.

A CRediT author-statement generator that renamed itself, then went quiet for two years.

◆ Current state

CRediTas turns a contributor-roles table into a CRediT Author Statement for a paper. The 0.2.0 release in April 2023 did the heavy lifting — package rename, a full object_verb() API rename, and output that drops straight into R Markdown or Quarto. The 0.3.0 release in August 2025 is the only activity since and carries no changelog text beyond a pointer to NEWS.md.

◆ Where it's heading

Development front-loaded a breaking cleanup during rOpenSci review and has coasted since. The design bet made in 0.2.0 — return a string for inline use rather than write a file — pointed the package at literate authoring workflows rather than at standalone scripts, and nothing since has moved away from it. The empty 0.3.0 note makes the current direction impossible to read from the feed.

◆ Prediction

Too little is published to call the next move; the 0.3.0 entry would need to carry its actual changes for the trajectory to be readable from the changelog at all.

2.5

mirai removed its dispatcher process and added memory backpressure to the queue.

◆ Current state

The async evaluation framework releases roughly monthly and moves fast at the architecture level. In 2.7.0 the dispatcher stopped being a separate process and became a thread, after its loop had already been rewritten in C inside nanonext one release earlier. The same release added an opt-in memory budget for queued task payloads and try_mirai(), which returns NULL immediately rather than blocking when that budget is exhausted.

◆ Where it's heading

Two threads of work run together: cutting overhead out of the task path — thread-based dispatcher, in-process transport for synchronous daemons, lower per-element dispatch cost in mirai_map() — and making the framework safe to embed in an event loop, where blocking the host R thread is not acceptable. Deployment reach is growing too, with http_config() launching remote daemons over HTTP APIs and auto-configuring for Posit Workbench. Each release pins a minimum nanonext version, so the two packages advance as one unit.

◆ Prediction

With backpressure in place but opt-in, the open question these notes leave is whether a default memory budget arrives; continued overhead reduction and Shiny-facing non-blocking paths are the safer bet.
