As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy.

Looking at https://github.com/boostorg/boost/actions/workflows/ci.yml I see random CMake failures caused by """ CMake Error at libs/numeric/odeint/CMakeLists.txt:39 (target_link_libraries): The link interface of target "boost_numeric_odeint" contains: Boost::mpi but the target was not found. Possible reasons include: * There is a typo in the target name. * A find_package call is missing for an IMPORTED target. * An ALIAS target is missing. """ Apparently, CMake 3.30 is less forgiving about ODEint linking to Boost::mpi when that target doesn't exist. (The reason Boost::mpi doesn't exist is because MPI libraries are only enabled when BOOST_ENABLE_MPI is ON, and it's OFF by default in these CI runs.) So the CMakeLists.txt file for ODEint needs to be fixed to only link to Boost::mpi when BOOST_ENABLE_MPI is ON.

I have failed to build the beta under Alpine Linux 3.20.1, using g++13, variant=release, cxxstd=23. It looks like the new Boost.Process doesn't support the musl C library: #22 292.7 libs/process/src/posix/close_handles.cpp:50:10: fatal error: gnu/libc-version.h: No such file or directory #22 292.7 50 | #include #22 292.7 | ^~~~~~~~~~~~~~~~~~~~ #22 292.7 compilation terminated. #22 294.7 #22 294.7 "g++" -std=c++23 -fvisibility-inlines-hidden -fPIC -m64 -pthread -O3 -finline-functions -Wno-inline -Wall -fvisibility=hidden -DBOOST_ALL_NO_LIB=1 -DBOOST_ASIO_NO_DEPRECATED -DBOOST_COBALT_USE_STD_PMR=1 -DBOOST_FILESYSTEM_DYN_LINK=1 -DBOOST_PROCESS_DYN_LINK=1 -DBOOST_PROCESS_SOURCE=1 -DNDEBUG -I"." -c -o "bin.v2/libs/process/build/gcc-13/release/x86_64/cxxstd-23-iso/threading-multi/visibility-hidden/posix/close_handles.o" "libs/process/src/posix/close_handles.cpp" #22 294.7 #22 294.7 ...failed gcc.compile.c++ bin.v2/libs/process/build/gcc-13/release/x86_64/cxxstd-23-iso/threading-multi/visibility-hidden/posix/close_handles.o... Full details here: https://github.com/boostorg/process/issues/386 Note that Alpine is thoroughly used alongside Docker because it's extremely lightweight in comparison to other distributions. I think we should fix this before the release. Other than that, there are numerous warnings, and I assume most (or all) of them are spurious. The rest of my email contains the warnings I got with the libraries that produced them, in case the authors want to fix them. 1.
