If nothing stands out being really wrong, I'll go ahead and commit it by end of week. OK?

      +
    • New features: +
        +
      • Support for the D programming language has been updated to version + 2.100.1 of the language and run-time library. Full changelog for this + release and previous releases can be found on the + dlang.org + website. +
        • +
      • On supported targets, the __traits(compiles) expression + can now be used to determine whether a target-specific built-in is + available without error during CTFE + (PR101127). +
        • +
      • Partial support for directly importing C99 sources into a D + compilation (ImportC) + has been added to the language. A notable missing feature is support + for preprocessing C imports, which can be worked around by + preprocessing all C sources used for importing ahead of time. +
        • +
      +
      • +
    • New language options: +
        +
      • -fcheck=, enables or disables the code generation of + specific run-time contract checks. +
        • +
      • -fcheckaction=, controls the run-time behaviour on an + assert, array bounds check, or final switch contract failure. The + default is -fcheckaction=throw. +
        • +
      • -fdump-c++-spec=, dumps all compiled + extern(C++) declarations as C++ code to a file. + The supplimentary option -fdump-c++-spec-verbose turns on + emission of comments for ignored declaration in the generated C++ spec. +
        • +
      • -fextern-std=, controls which C++ standard + extern(C++) declarations are compiled to be compatible + with. The default is -fextern-std=c++17. +
        • +
      • -fpreview=, added to enable upcoming D language features + in the compiler. +
        • +
      • -frevert=, added to revert D language changes to support + older D codebases that need more time to transition. +
        • +
      • -fsave-mixins=, saves mixins expanded at compile-time to + a file. +
        • +
      +
      • +
    • Deprecated and removed features: +
        +
      • The -Wtemplates compiler switch has been removed, as it + had been superceded by -ftransition=templates, which more + accurately reports on which templates have been instantiated. +
        • +
      • The -ftransition=dip25 and + -ftransition=dip1000 compiler switches have been renamed + to -fpreview=dip25 and -fprefix=dip1000. +
