This blog is updated daily.
A general description is here.
The parser has been updated to work with ‘bison’ 3.8.2, which is now used for the pre-generated parsers in ‘gram.c’, ‘file.c’, and ‘gramRd.c’. A few parser error messages have changed, which may affect code that relies on exact messages.
Rtools44 has experimental support for 64-bit ARM (‘aarch64’) CPUs _via_ the LLVM 17 toolchain using ‘lld’, ‘clang’/‘flang-new’ and ‘libc++’.
The makefiles and installer scripts for Windows have been tailored to Rtools44, an update of the Rtools43 toolchain. It is based on GCC 13 and newer versions of MinGW-W64, binutils and libraries (targeting 64-bit Intel CPUs). R-devel can no longer be built using Rtools43 without changes.
The legacy graphics devices ‘pictex()’ and ‘xfig()’ are now deprecated. They do not support recent graphics enhancements and their font handling is rudimentary. The intention is to retain them for historical interest as long as they remain somewhat functional.
