The messy-date parser rewrote its core in Rust and came out 300x faster.
A side-by-side editorial comparison of lightr and textshaping — release velocity, themes, recent moves, and the top alternatives to consider.
Reorganised its parsers by vendor, then opened the parser slot to users.
lightr reads spectrometry files from the proprietary formats that instrument vendors ship, and its recent releases have been about the structure of that parser collection rather than adding one more format. Version 2.0.0 renamed every low-level parser from lr_parse_<extension>() to lr_parse_<brand>_<extension>(), a breaking change made specifically so two vendors can share a file extension without colliding, and restored binary parsing for Avantes AvaSoft 8.4 using vendor-supplied format documentation. Version 2.1.0 follows through by exposing a parser argument on the high-level functions.
Rewrote its shaping engine for bidirectional text, then spent a year fixing what that broke.
textshaping is the text layout layer beneath R's modern graphics stack, feeding ragg, ggplot2 and marquee. Version 1.0.0 rewrote the shaping engine to honour the global direction of text, adding a direction argument that defaults to automatic detection, align settings that resolve against that direction, and ICU-based soft break locations that handle ideographic scripts properly. The five releases since have been consecutive bug fixes against that rewrite — bidi embedding arrangement, line positioning with mixed sizes, a weak hash in the shape cache, a signed integer overflow, and font fallback regressions.

The package is moving from a fixed set of formats it knows about to a dispatch system users can extend. The brand-qualified naming and the parser argument are two halves of the same design: name parsers unambiguously, then let callers select or supply one. Alongside that runs steady attention to metadata fidelity — measurement timestamps, checksum verification against tampering, and timezone handling that survived upstream tzdata removing legacy codes.
Expect additional vendor parsers to arrive under the new brand-qualified scheme, and the custom-parser path to absorb formats the maintainers do not want to support directly. The entries do not name specific instruments planned next.

The package has moved from Latin-first layout to script-agnostic layout in two rewrites, 0.4.0 and 1.0.0, and is now in the long correctness tail that follows. The bug reports arriving from ggplot2, ragg and marquee issue numbers show how it works in practice: textshaping bugs surface as rendering defects in the packages above it, which is why so many fixes here cite another package's issue tracker.
Expect continued fixes driven by downstream rendering reports rather than new layout features, as the 1.0.x series stabilises. The font fallback path has produced two of the recent bugs and is the most likely source of the next.
