This will be fixed for the final release. If you want to fix it locally, edit the file libs/context/build/Jamfile.v2: - else if [ os.platform ] = "ARM" { tmp = aapcs ; } + else if [ os.platform ] in ARM ARM64 { tmp = aapcs ; } The web site has not yet been updated (tomorrow, I hope) but when it is, the release notes will be at: https://www.boost.org/users/history/version_1_83_0.html Please try the beta and report any problems you encounter. Thanks to everyone who contributed to the release. -- Boost Release Team
