A side-by-side editorial comparison of admiralophtha and sftime — release velocity, themes, recent moves, and the top alternatives to consider.
Ophthalmology ADaM support is migrating its derivations upstream into admiral core.
admiralophtha supplies ophthalmology-specific ADaM templates and vignettes — ADBCVA, ADOE, ADVFQ — on top of admiral. Releases arrive roughly twice a year and are dominated by template and vignette modernisation plus a long, deliberate deprecation of the package's own criterion-flag helper in favour of admiral::derive_vars_crit_flag(). The 1.5.0 release advances that deprecation to its warning phase and adds a template explorer.
The spatiotemporal companion to sf, moving at the pace of the packages around it.
sftime extends sf with an active time column, giving R a data frame class for data that is both spatial and temporal. Its recent history is almost entirely integration work: 0.3.0 added conversion methods from spatstat point patterns, sftrack and sftraj movement objects and cubble data frames, plus dedicated tidyr::drop_na() and dplyr::dplyr_reconstruct() methods. The two releases since are a namespace version-check correction and a switch from the magrittr pipe to the native pipe in examples.

The arc is consolidation: functions the package invented are being retired as admiral core grows generic equivalents, leaving admiralophtha as the place where ophthalmology conventions are documented. Recent releases spend their weight on templates and vignettes — VFQ guidance alignment, IOP parameter mapping, subject-key options — rather than new exported code. Deprecations are run on a fixed six-month, one-release-per-phase clock, which makes the migration path unusually legible.
derive_var_bcvacritxfl() should reach its error phase and then removal over the next two releases, with the accompanying work being ADBCVA vignette and template edits rather than new functions.

The two releases since are a namespace version-check correction and a switch from the magrittr pipe to the native pipe in examples.
The package's job is to be interoperable, so its releases follow whatever the surrounding spatial and tidyverse packages do. The dplyr_reconstruct() work is the clearest example of why that matters: inheriting sf's method caused column binding to silently return an sf object where an sftime object was expected, which is the kind of class-preservation bug that only surfaces two steps downstream. Development is sparse, roughly one release a year.
Expect further conversion methods as new spatiotemporal classes appear in the R spatial ecosystem, and continued tracking of dplyr and tidyr generics. The entries do not indicate any planned change to the sftime class itself.
