What is crosstalk?

crosstalk is frozen infrastructure: four releases in five years, mostly CRAN upkeep.

crosstalk provides the shared-selection and filtering layer that lets independent htmlwidgets communicate on a page without Shiny. Its visible history is four releases across five years, one of which made a substantive change and three of which were fixes. The most recent exists only to clear an R CMD check NOTE.

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.

crosstalk is frozen infrastructure: four releases in five years, mostly CRAN upkeep.

◆ Current state

crosstalk provides the shared-selection and filtering layer that lets independent htmlwidgets communicate on a page without Shiny. Its visible history is four releases across five years, one of which made a substantive change and three of which were fixes. The most recent exists only to clear an R CMD check NOTE.

◆ Where it's heading

The package is finished in the sense that matters: it does one thing, widget authors depend on it, and it changes when R or CRAN forces it to. The single directional move here is 1.2.0 dropping the bundled Bootstrap dependency so crosstalk stops imposing a CSS framework on the pages that embed it. Nothing since suggests further design work.

◆ Prediction

The next release is most likely another CRAN-compliance fix; the entries show no feature work in progress.

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.
