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 probably?

The package that made calibration a step instead of an afterthought.

probably started as a small utility for class predictions and equivocal zones, and version 1.0.0 turned it into tidymodels' calibration and uncertainty package: cal_plot_*, cal_estimate_*, cal_validate_* and cal_apply across binary, multiclass and regression problems, plus conformal prediction intervals. Since then the work has been consolidation — a large internal refactor with no API change, split conformal and conformal quantile regression, bound_prediction(), and required_pkgs() and butcher methods so conformal objects can be deployed and stripped.

0.0

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.

The package that made calibration a step instead of an afterthought.

◆ Current state

probably started as a small utility for class predictions and equivocal zones, and version 1.0.0 turned it into tidymodels' calibration and uncertainty package: cal_plot_*, cal_estimate_*, cal_validate_* and cal_apply across binary, multiclass and regression problems, plus conformal prediction intervals. Since then the work has been consolidation — a large internal refactor with no API change, split conformal and conformal quantile regression, bound_prediction(), and required_pkgs() and butcher methods so conformal objects can be deployed and stripped.

◆ Where it's heading

The recent releases are about making these objects survive leaving the session. butcher and required_pkgs() methods are what a model needs to be pinned, containerised and served, and their arrival alongside workflows adding a tailor postprocessing stage and vetiver adding probably support points the same way: calibration is being moved out of analysis scripts and into the deployed pipeline. The cal_*_none() reference implementations are the tell that calibration is now something people tune rather than apply once.

◆ Prediction

Expect the calibration functions to be reachable directly from a tuned workflow's postprocessing stage rather than applied to predictions afterwards, following the tailor integration that workflows just shipped.
