This blog is updated daily.
A general description is here.
There is preliminary support for C++26 in GCC >= 14, Apple clang >= 16 and LLVM clang >= 17.
‘R_GetCurrentSrcref(skip)’ now skips calls rather than ‘srcref’s, consistent with counting items in the ‘traceback()’ display. If ‘skip == NA_INTEGER’, it searches for the first ‘srcref’, starting at the current evaluation state and proceeding through the call stack; otherwise, it returns the ‘srcref’ of the requested entry from the call stack.
‘R CMD build’ now supports ‘--compression=zstd’ on platforms with sufficient support for ‘zstd’.
‘options(show.error.locations = TRUE)’ once again shows the most recent known location when an error is reported. Setting its value to ‘"bottom"’ is no longer supported. Numerical values are converted to logical.
C API function ‘R_GetCurrentSrcref(skip)’ now returns ‘srcref’ entries correctly. (Note that there is also a change to the interpretation of ‘skip’; see the C-LEVEL API entry above.)
‘tools::Rd2latex()’ now removes leading and trailing spaces from \alias entries as documented, fixing indexing and linking hiccups in some PDF manuals.
‘R CMD Rd2pdf’ works again on an installed package directory containing LaTeX help (from option ‘--latex’), thanks to a report by Peter Ruckdeschel.
