lubridate vs themis: at a glance
What is lubridate?
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.
What is themis?
themis is back to adding real resampling algorithms after a documentation-heavy stretch.
themis supplies recipes steps for handling class imbalance in tidymodels. The 1.0.x line was consumed by documentation accuracy, message translation and internal consistency work. Version 1.1.0 returns to substance with two new under-sampling methods.

lubridate
0.0ANALYTICS
lubridate ships parsing fixes, timezone-data churn, and a long-overdue MIT relicense.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
Expect further releases driven by tzdata and R-devel changes, with parsing fixes arriving as locale and format edge cases get reported.
themis
2.5ANALYTICS
themis is back to adding real resampling algorithms after a documentation-heavy stretch.
◆ Current state
themis supplies recipes steps for handling class imbalance in tidymodels. The 1.0.x line was consumed by documentation accuracy, message translation and internal consistency work. Version 1.1.0 returns to substance with two new under-sampling methods.
◆ Where it's heading
The package grows by adding algorithms rather than restructuring itself. tomek() was rewritten to handle multiple classes and drop the unbalanced dependency, case weights arrived at 1.0.0, and cluster-centroid and condensed-nearest-neighbour under-sampling arrive now — each shipped as both a recipes step and a direct-implementation function.
◆ Prediction
Expect further under- and over-sampling methods in the same paired form, as the package fills out coverage of the standard class-imbalance literature.
