This blog is updated daily.
A general description is here.
‘memDecompress(type = "unknown")’ recognizes compresion in the defailt ‘zlib’ format as used by ‘memCompress(type = "gzip")’.
(*Experimental:*) ‘memCompress()’ and ‘memDecompress()’ have a new type ‘"libdeflate"’ which use the ‘libdeflate’ library (<URL: https://github.com/ebiggers/libdeflate>) if installed. This uses the same type of compression as their default ‘type = "gzip"’ but is substantially faster on some common plaftorms: the speed-up may depend on the library version.
This option may replace ‘type = "gzip"’ before release.
The ‘confint()’ and ‘profile’ methods for ‘"glm"’ objects have gained a possibility to do profiling based on the Rao Score statistic in addition to the default Likelihood Ratio. This is controlled by a new ‘test =’ argument.
In ‘setRepositories()’ the repositories can be set using their names via ‘name =’ instead of index ‘ind =’.
‘range(<DT_with_Inf>, finite = TRUE)’ now work for objects of class ‘"Date"’, ‘"POSIXct"’, and ‘"POSIXlt"’ with infinite entries, analogously to ‘range.default()’, as proposed by Davis Vaughan on R-devel. Other ‘range()’-methods can make use of new ‘.rangeNum()’.
‘kappa(., exact = TRUE, norm = *)’ now works for all norms and also for complex matrices. In symmetric / triangular cases, new argument ‘uplo = "U" | "L"’ allows to specify the upper or lower triangular part.
Enviroment variable ‘R_SYSTEM_ABI’ is no longer used and so no longer recorded in ‘etc/Renviron’ (it was not on Windows and was only ever used when preparing package ‘tools’).
‘kappa()’ and ‘rcond()’ work correctly in more cases; ‘kappa(., norm = "2")’ now warns that it computes the 1-norm with (default) ‘exact = FALSE’; prompted by Mikael Jagan's quite comprehensive PR#18543.
Rd skeletons generated by ‘prompt()’ or ‘promptData()’ now use a dummy title (so ‘R CMD build’ works). ‘tools::checkRdContents()’ has been updated to detect such template leftovers, including from ‘promptPackage()’.
