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 rotl?

rotl's whole release history is keeping name matching honest against a moving taxonomy.

Nearly every entry concerns `tnrs_match_names()`, the function that maps user-supplied names onto Open Tree taxonomy ids. 3.1.0 changed which taxon wins a multi-way match — highest matching score rather than lowest OTT id, reversing the rule 3.0.4 introduced. 3.0.12 defaulted `context_name` to 'All life' so a context inferred from the first name could not silently skew later ones. 3.0.11 made a total failure to match return an empty tibble with a warning instead of an error. The rest are small fixes tracking Open Tree API changes.

lubridate vs rotl: editorial side-by-side

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.

rotl's whole release history is keeping name matching honest against a moving taxonomy.

◆ Current state

Nearly every entry concerns `tnrs_match_names()`, the function that maps user-supplied names onto Open Tree taxonomy ids. 3.1.0 changed which taxon wins a multi-way match — highest matching score rather than lowest OTT id, reversing the rule 3.0.4 introduced. 3.0.12 defaulted `context_name` to 'All life' so a context inferred from the first name could not silently skew later ones. 3.0.11 made a total failure to match return an empty tibble with a warning instead of an error. The rest are small fixes tracking Open Tree API changes.

◆ Where it's heading

The recurring problem is ambiguity: names match several taxa, and the package has changed its tie-breaking rule twice while making failures and edge cases return predictable objects rather than errors. Nothing here expands what rotl can retrieve; it makes what it retrieves reproducible. The feed also stops in mid-2023, so the package appears dormant.

◆ Prediction

Nothing in the window suggests new capability. If a release comes, the pattern says it will follow an Open Tree API change or another matching-behaviour correction.
