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.

What is rredlist?

rredlist threw out its species-centric API in 1.0.0 and rebuilt around assessments.

rredlist 1.0.0 is a hard break: the IUCN Red List API moved to v4, and the package followed by dropping v3 support entirely, reorganising around assessments rather than species, renaming or removing most functions, changing returned data structures, and requiring users to generate a new API key. The two releases since are consolidation on that new shape — `rl_assessment_list()` and `rl_assessment_extract()` for retrieving and unpacking many assessments at once, a `scope` argument on the `*_latest()` functions, and NULL-safe extraction.

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.

rredlist threw out its species-centric API in 1.0.0 and rebuilt around assessments.

◆ Current state

rredlist 1.0.0 is a hard break: the IUCN Red List API moved to v4, and the package followed by dropping v3 support entirely, reorganising around assessments rather than species, renaming or removing most functions, changing returned data structures, and requiring users to generate a new API key. The two releases since are consolidation on that new shape — `rl_assessment_list()` and `rl_assessment_extract()` for retrieving and unpacking many assessments at once, a `scope` argument on the `*_latest()` functions, and NULL-safe extraction.

◆ Where it's heading

Post-1.0.0 work is clearly aimed at bulk use: fetch many assessments, pull a chosen field out of each. That is a different usage pattern from the one-species-at-a-time queries the v3-era functions encouraged, and it suits the conservation-analysis workloads the package is actually used for. Deprecated v3 functions are still present and flagged for eventual removal.

◆ Prediction

The deprecated v3-era functions are the obvious next thing to disappear, and further bulk-retrieval helpers are likely given both post-1.0 releases went that way.
