Glad to announce LDC 1.31.0. Major changes:

• Based on D 2.101.2.
  • ImportC: The C preprocessor isn't invoked yet.
• mac/iOS arm64: Linking with -g is working again without unaligned pointer warnings/errors.
• Preliminary support for LLVM 15. Thanks @jamesragray for helping out!
• Initial ABI support for 64-bit RISC-V. Thanks @Ast-x64!

Full release log and downloads: https://github.com/ldc-developers/ldc/releases/tag/v1.31.0

Thanks to all contributors & sponsors!
