What is bbotk?

bbotk is generalizing from an optimizer toolkit into an evaluation framework.

bbotk is the black-box optimization backend behind mlr3 tuning: search spaces, terminators, archives, and an async layer built on rush. Recent releases pair steady async-API buildout with removal of the deprecated arguments that preceded it. The 1.9.0 release introduced EvalInstance as a base class for OptimInstance, separating evaluating an objective from optimizing one.

What is flexdashboard?

flexdashboard has slowed to a fix-only trickle since the bslib theming rework

flexdashboard turns R Markdown into dashboard layouts, and its last structural release was 0.6.0's integration with bslib, which handed theming to shared tidyverse infrastructure and opened the Bootstrap 4 path. Everything after that is Bootstrap 5 compatibility, navigation polish, and rendering fixes — with a two-and-a-half-year gap between 0.6.2 and 0.6.3.

bbotk is generalizing from an optimizer toolkit into an evaluation framework.

◆ Current state

bbotk is the black-box optimization backend behind mlr3 tuning: search spaces, terminators, archives, and an async layer built on rush. Recent releases pair steady async-API buildout with removal of the deprecated arguments that preceded it. The 1.9.0 release introduced EvalInstance as a base class for OptimInstance, separating evaluating an objective from optimizing one.

◆ Where it's heading

Two threads run through the visible history. The first is async optimization maturing: ArchiveAsync gained a full push/finish/fail vocabulary over rush tasks in 1.11.0, and 1.12.0 deleted the deprecated extra arguments it replaced. The second is dependency consolidation, with custom C hypervolume code handed to moocore and rush pinned to 1.0.0, trimming maintenance surface as the async path becomes the default.

◆ Prediction

The deprecation removals in 1.12.0 suggest the async archive API is now treated as settled; the next releases most likely build on EvalInstance rather than continuing to churn ArchiveAsync.

flexdashboard has slowed to a fix-only trickle since the bslib theming rework

◆ Current state

flexdashboard turns R Markdown into dashboard layouts, and its last structural release was 0.6.0's integration with bslib, which handed theming to shared tidyverse infrastructure and opened the Bootstrap 4 path. Everything after that is Bootstrap 5 compatibility, navigation polish, and rendering fixes — with a two-and-a-half-year gap between 0.6.2 and 0.6.3.

◆ Where it's heading

The package has reached the stage where its releases exist to keep it working against newer Bootstrap, knitr and Quarto behavior rather than to add anything. Theming was outsourced to bslib, icons to Font Awesome, and the remaining surface is the layout syntax itself, which has not changed. The long release gaps are the clearest signal here.

◆ Prediction

The entries do not support a confident prediction of new capability; the realistic read is continued Bootstrap 5 compatibility fixes as bslib moves, at whatever cadence maintenance allows.
