  • cpp11 now requires R >=4.0.0, in line with the
    tidyverse version policy (#411).

  • Because cpp11 now requires R >=4.0.0, a number of previously optional tools
    are now always available, allowing us to remove some dead code. In
    particular:

    • R_UnwindProtect() is always available, so the defines HAS_UNWIND_PROTECT
      and CPP11_UNWIND are no longer useful.

    • ALTREP is always available, so the file cpp11/altrep.hpp and the define
      HAS_ALTREP are no longer useful.

    We would like to remove the dead code regarding these tools in the future, so
    we ask that you please remove usage of them from your own packages (#411).

  • R_NO_REMAP and STRICT_R_HEADERS are now conditionally defined only if they
    have not already been defined elsewhere. This is motivated by the fact that
    R_NO_REMAP is becoming the default for C++ code in R 4.5.0 (#410).

  • Fixed a small protection issue flagged by rchk (#408).
