What is pr2database?

The protist reference database keeps widening past the rRNA gene it was built on.

PR2 curates ribosomal reference sequences for eukaryotes, distributed as flat files and through a web interface, with each release crediting the specialists who curated individual clades. Since 2022 the structural changes have outweighed the curation: one combined SSU database replaced the separate ones, the taxonomy moved from eight levels to nine, and companion databases for ribosomal operons, mixoplankton and mitochondrial COI have been linked in.

What is transltr?

A new R localization package that reached CRAN and immediately downgraded itself to experimental.

transltr is a young package for supporting many languages in R, built around Text and Translator classes. Its entire public history is four release candidates over four weeks in early 2025 — there are no final tags, so the RC is the release event here. Two of the four exist only to satisfy CRAN reviewers.

The protist reference database keeps widening past the rRNA gene it was built on.

◆ Current state

PR2 curates ribosomal reference sequences for eukaryotes, distributed as flat files and through a web interface, with each release crediting the specialists who curated individual clades. Since 2022 the structural changes have outweighed the curation: one combined SSU database replaced the separate ones, the taxonomy moved from eight levels to nine, and companion databases for ribosomal operons, mixoplankton and mitochondrial COI have been linked in.

◆ Where it's heading

The database is becoming a hub rather than a single file. Each recent release integrates something maintained elsewhere, with the ROD, EukRibo, Mixoplankton and now eKOI databases reachable through the same interface, while the SSU flat files themselves change little between versions. Curation continues underneath, clade by clade, at a pace set by which specialist contributed that cycle.

◆ Prediction

Expect the next release to integrate or refresh another linked database while the SSU files see routine curation, following the pattern of the last three.

A new R localization package that reached CRAN and immediately downgraded itself to experimental.

◆ Current state

transltr is a young package for supporting many languages in R, built around Text and Translator classes. Its entire public history is four release candidates over four weeks in early 2025 — there are no final tags, so the RC is the release event here. Two of the four exist only to satisfy CRAN reviewers.

◆ Where it's heading

The arc is unusually candid about instability. The first release shipped with an explicit instruction to treat it as beta until 1.0.0, and 0.1.0 then went further, reverting the package's lifecycle badge from a firmer status back to experimental because the maintainer had broken more than intended — naming the Text and Translator methods as the parts still likely to move. Test coverage is repeatedly cited as the thing holding the package together while the interface is not yet fixed.

◆ Prediction

The self-declared plan is a 1.0.0 that settles the Text and Translator method signatures; until then expect further breaking changes, and the release notes will most likely keep pointing at NEWS.md rather than summarising them.
