Adding chemical databases with one hand while public ones close programmatic access with the other.
A side-by-side editorial comparison of admiralvaccine and lobstr — release velocity, themes, recent moves, and the top alternatives to consider.
Vaccine ADaM templates exist and are maintained, but development has slowed to housekeeping.
admiralvaccine provides vaccine-specific ADaM templates and vignettes — ADCE, ADFACE, ADIS, ADSL — on top of admiral. The last two releases contain no functional change at all: 0.5.0 is maintainer handover, template fixes and lint config, and 0.6.0 is CRAN documentation compliance plus an ecosystem-wide Ask AI widget. Real work was last visible in 0.4.0's criterion-flag deprecation.
R's object inspector is losing its view of the internals as CRAN closes off the private C API.
lobstr exposes R's internal object representation — sizes, addresses, reference counts, abstract syntax trees. Its two most recent releases are both driven by R's move to a restricted public C API: 1.1.3 stopped reporting a vector's truelength and reworked the reference indicator into refs:n, and 1.2.0 changed what sxp(expand = "environment") shows in order to stay compliant. 1.2.0 also adds src() for exploring srcref objects.

The package has moved from building out vaccine domains to keeping them on CRAN. Each release tracks whatever admiral changed upstream and clears whatever CRAN flagged, and the changelogs have shifted from derivation notes to merged-PR lists. Maintainer churn in 0.5.0 is the clearest sign that this is a maintenance-mode package inside an otherwise active ecosystem.
The next release most likely continues the pattern — dependency and documentation alignment with admiral core plus deprecation follow-through — unless a new vaccine reporting requirement forces domain work.

The package is being rebuilt inside a shrinking window of what R permits. Each release trades some introspection depth for API conformance while trying to keep the diagnostic value intact — showing promise expressions instead of internal frame structures, replacing named with a documented refs scale. Where the constraint does not bite, development continues normally: src() is genuinely new, and the environment-binding fixes remove long-standing errors on for-loop and immediate bindings.
Expect further conformance work, since the notes describe it as ongoing, with any remaining non-API-dependent readouts either reworked or dropped as R tightens further.
