It seems that "Apple Clang 1300.0.29.30" is the oldest version based on the last R arrow package check information: * https://cran.r-project.org/web/checks/check_results_arrow.html * https://cran.r-project.org/web/checks/check_flavors.html#r-oldrel-macos-x86_64 It's based on LLVM 12.0.0. See also: https://en.wikipedia.org/wiki/Xcode#Xcode_11.0_-_14.x_(since_SwiftUI_framework)_2 LLVM 12.0.0 has `-std=c++20`. See also: https://clang.llvm.org/cxx_status.html#cxx20 So we may be able to use C++20 on CRAM. (We may not be able to use some C++20 features.) -- This is an automated message from the Apache Git Service.
