What is stringi?

stringi has spent two years on build hardening since its Unicode 15.1 reset.

stringi is the ICU-backed string engine under a large share of R's text handling. Since the 1.8.1 reset in late 2023 — which bundled ICU 74.1, dropped Solaris, and raised the compiler floor — every subsequent release has been build and portability maintenance: PROTECT-stack fixes, Windows build errors, compiler warnings. The 1.8.8 release in July 2026 continues that pattern by dropping the configure script's C++11 fallback.

What is tern.mmrm?

An MMRM tabulation package that has published nothing since its 2024 CRAN releases.

tern.mmrm wraps mixed models for repeated measures into the tern tabulation and plotting layer used by teal clinical modules. The visible history ends with three CRAN releases in mid-to-late 2024; before that the feed carries only automated version bumps from 2022, three of which have just been backfilled into the record. The most recent substantive change adds axis limit arguments to the LS-means plot.

stringi has spent two years on build hardening since its Unicode 15.1 reset.

◆ Current state

stringi is the ICU-backed string engine under a large share of R's text handling. Since the 1.8.1 reset in late 2023 — which bundled ICU 74.1, dropped Solaris, and raised the compiler floor — every subsequent release has been build and portability maintenance: PROTECT-stack fixes, Windows build errors, compiler warnings. The 1.8.8 release in July 2026 continues that pattern by dropping the configure script's C++11 fallback.

◆ Where it's heading

The package has reached feature stability and is maintained as infrastructure. Releases arrive when a toolchain, platform, or check regime changes, not when users ask for capability. The two-and-a-half year gap between 1.8.1's Unicode bump and anything comparable suggests the next directional move will again be an ICU bundle refresh rather than new API surface.

◆ Prediction

The next release is most likely another build-time fix or an ICU bundle update to a newer Unicode version; the entries show no in-progress feature work.

0.0

An MMRM tabulation package that has published nothing since its 2024 CRAN releases.

◆ Current state

tern.mmrm wraps mixed models for repeated measures into the tern tabulation and plotting layer used by teal clinical modules. The visible history ends with three CRAN releases in mid-to-late 2024; before that the feed carries only automated version bumps from 2022, three of which have just been backfilled into the record. The most recent substantive change adds axis limit arguments to the LS-means plot.

◆ Where it's heading

Content per release is thin and largely organisational: a maintainer change, replacing scda with random.cdisc.data in vignettes, and adapting to new {mmrm} versions. The package appears to be in maintenance, tracking its upstream dependency rather than developing independently. The 2022 entries now visible are release-automation commits, not releases in any meaningful sense.

◆ Prediction

Nothing here signals new functionality; the realistic next event is another compatibility release when {mmrm} or {rtables} changes underneath it.
