httpuv
httpuv ships almost nothing, which is what you want from the web server under Shiny
A side-by-side editorial comparison of later and zip — release velocity, themes, recent moves, and the top alternatives to consider.
later spends its releases keeping R's event loop compiling against moving toolchains.
later provides the event loop that lets R schedule callbacks, underpinning shiny, httpuv and most async work in the language. Recent releases are overwhelmingly build and compatibility work: Rcpp error-handling changes, a C23 namespace collision with glibc, and header ordering to satisfy Rcpp auto-includes.
zip 3.0 added encryption, turning a plumbing package into a complete archive tool.
zip creates and extracts archives from R without depending on external tools. Its 2.x line was incremental — a type column in zip_list(), symlink handling on Unix, hidden shared-library symbols. Version 3.0.0 changed the package's shape by adding password-protected archives and vectorized extraction.

The API is settled enough that the release calendar is set by the surrounding ecosystem rather than by any feature plan. 1.4.5 cleaned house by dropping pre-unwind-protect fallbacks, and 1.4.6 carries the only recent change a user would notice at all — lower CPU use when idle at the console.
Expect further releases pinned to compiler and Rcpp changes, with the observable surface staying essentially where it is.
zip creates and extracts archives from R without depending on external tools. Its 2.x line was incremental — a type column in zip_list(), symlink handling on Unix, hidden shared-library symbols. Version 3.0.0 changed the package's shape by adding password-protected archives and vectorized extraction.
Development is moving from listing and extracting toward parity with what users expect of a general archive utility: encryption schemes including WinZIP AES-256, an encryption column so an archive can be inspected before extraction, and thread counts that respect the session's Ncpus setting. The 3.0.x releases since are consolidation on that new surface.
Expect continued refinement of the encryption and threading paths, with remaining symlink and permission edge cases on Unix the most likely source of the next fixes.
