A general description is here.
Dynamic help now does a much better job rendering package ‘DESCRIPTION’ metadata.
There is an experimental ‘configure’ option ‘--with-libdeflate-compression’ which uses ‘libdeflate’ rather than ‘libz’ to (de)compress R objects in lazy-load databases, if the ‘libdeflate’ library and headers are available. Typically tasks spend up to 5% of their time on such operations, although creating lazy-data databases is one of the exceptions.
_pro tem_ this can also be selected by setting environment variable ‘R_USE_LIBDEFLATE_FOR_LAZYLOAD’ to ‘yes’.
‘tools::checkDocFiles()’ and ‘tools::checkRdContents()’ now also check internal Rd files by default, but “specially” (ignoring missing documentation of arguments).
