#> CHANGES IN R 4.4.3
#>
#> INSTALLATION:
#>
#> (cid:136) R can be installed using C23 (for example with ‘-std=gnu23’ or ‘-std=gnu2x’) with
#> recent compilers including gcc 12(cid:21)14, Apple clang 15(cid:21)16, LLVM clang 17(cid:21)20 and
#> Intel icx 2024.2.
#> It can be installed with the upcoming (at the time of writing) gcc 15, which defaults
#> to C23.
#>
#> C-LEVEL FACILITIES:
#>
#> (cid:136) The functions R_strtod and R_atof now allow hexadecimal constants without an
#>
#> exponent, for compatibility with their C99 versions (PR#18805).
#>
#> UTILITIES:
#>
#> (cid:136) R CMD build and R CMD check now allow reference output
#>
#> for demo scripts
#> (‘demo/demo.Rout.save’ (cid:28)les) to be shipped with the package, as proposed by
#> Torsten Hothorn in PR#18816.
#>
#> BUG FIXES:
#>
#> (cid:136) kappa(A, exact=TRUE) for singular A returns Inf more generally, (cid:28)xing PR#18817
#>
#> reported by Mikael Jagan.
#>
#> (cid:136) Fixed URLs of the sun spots (sunspot.month etc) data sets and mention future
