bbotk
bbotk is generalizing from an optimizer toolkit into an evaluation framework.
A side-by-side editorial comparison of leaflet and lubridate — release velocity, themes, recent moves, and the top alternatives to consider.
leaflet relicensed to MIT and finished migrating off R's retired spatial stack
leaflet is the R binding for the Leaflet mapping library. Its recent releases are dominated by one long migration: away from sp, rgdal, rgeos and raster, and toward sf and terra. Version 2.2.3 completed the user-facing half of that - sp is no longer installed by default, and bundled datasets ship as sf objects - while also relicensing the package from GPL-2 to MIT.
lubridate ships parsing fixes, timezone-data churn, and a long-overdue MIT relicense.
lubridate is R's standard package for date-time manipulation. Recent releases are dominated by parsing correctness — partial datetimes, multiple format strings, month names colliding with the %a format — and by adapting to timezone database changes in R-devel. Version 1.9.5 also relicensed the package to MIT.

This is a package being brought into line with an ecosystem that changed underneath it. The retirement of rgdal and rgeos forced the terra and sf work; the license change and dependency reductions are the maintainers taking the opportunity to clean up while they are already in there. Feature work, such as the full viridisLite palette set, arrives as a side effect of the tidying.
With the sp path now opt-in and the retired geospatial dependencies gone, expect the remaining work to be small: palette and provider-tile handling, and keeping the bundled JavaScript current.

Version 1.9.5 also relicensed the package to MIT.
The feature surface has been stable since 1.9.0 deprecated the roll argument for roll_dst and added integer coercion for Duration, Period and Interval. What continues is a steady stream of parsing edge cases and tzdata churn the package absorbs on its users' behalf, which is most of what a date-time library's maintenance actually is.
Expect further releases driven by tzdata and R-devel changes, with parsing fixes arriving as locale and format edge cases get reported.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. leaflet and lubridate are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
