The clinical-report table engine learned Chinese, then learned to leave RTF entirely
A side-by-side editorial comparison of slider and textreuse — release velocity, themes, recent moves, and the top alternatives to consider.
Feature-complete since 2021, and every release since has been paying CRAN's C API bill
slider provides sliding-window and index-aware window functions for R, with a C implementation underneath and a specialised fast path for common aggregations. The user-facing surface has been stable since 0.3.0 in late 2022. Everything after that is compliance and platform work: STRING_PTR removed in 0.3.2, OBJECT() removed in 0.3.3, a vctrs callable's C signature corrected, and the minimum R version raised twice.
A dormant text-matching package revived, shipped as 1.0.0, and kept current with the tidyverse.
textreuse detects reused and quoted passages across document collections using minhash and locality-sensitive hashing, with local alignment for inspecting the matches it finds. After years of inactivity, the package reached a 1.0.0 CRAN release in May 2026 that folded accumulated feature work into one version — encoding control on corpus construction, deterministic skipped-document bookkeeping, and an align_local() that returns an empty alignment instead of erroring on non-matching texts. The 1.0.2 release since then is pure compatibility maintenance.

Two forces set the release schedule, and neither is feature demand. The first is CRAN closing off non-API C entry points, which packages reaching into R internals for speed have to unwind one accessor at a time — slider is on its second such release with no visible loss of function. The second is vctrs, whose breaking changes slider absorbs ahead of time; 0.2.2 exists solely to prepare for one. The last release that added anything callers can see was 0.3.0's slider_plus() and slider_minus() extension hooks.
Expect the pattern to continue: another non-API accessor removal or a vctrs compatibility release, rather than new window functions. The C-level surface is the only part of this package still moving.

The arc here is restoration rather than expansion. The work has gone into making the package survivable — silencing deprecated dplyr and tidyr selection and many-to-many join warnings, moving from dead Travis and AppVeyor configs to GitHub Actions, and validating across five R platform and version combinations. Release notes now lead with verification evidence rather than features, which is the signature of a maintainer stabilizing an inherited codebase.
Expect continued compatibility releases tracking tidyverse deprecations; nothing in these entries indicates new hashing or alignment capability is planned.
