About logger
R's logging package handed to new maintainers and rebuilt from the inside out
logger structures R logging around four composable pieces — a level threshold, a formatter, a layout and an appender — a design fixed at the 2018 CRAN release and unchanged since. The recent work is all underneath it. 0.4.0 made metadata computation lazy so expensive fields cost nothing unless a layout uses them, swapped the custom background-process appender for mirai, and added native GitHub Actions output. 0.4.1 followed with elapsed-time logging, call site location exposed to layouts, a cli-based formatter, and knitr chunk timing. 0.4.2 is a small maintenance release adding an ntfy appender.
