After far too long, release candidate files for 1.60.0 beta 4 are available at http://boost.cowic.de/rc/ 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. This helps ensure the candidates build OK before we push them out to SourceForge. Changes since rc3: * Boost.Test has been updated and now builds on Visual Studio Changes since rc1: * Boost.Sprit has been updated and Boost.Log now builds. * Boost.Math has been updated and now builds. Known issues (which will not be fixed for the beta): * Errors when building Boost.TypeErasure for older versions of Visual Studio. * Boost.Test fails when building on Darwin with gcc 4.9.2 The files (and associated md5s) are: MD5 (boost_1_60_0_b1_rc4.7z) = 63530c9594b24f56e5df79d910c9daeb MD5 (boost_1_60_0_b1_rc4.tar.bz2) = 29af12a1028536219a21517e953df4eb MD5 (boost_1_60_0_b1_rc4.tar.gz) = 74df7f5eb5e32f3a92b6141af3c6f541 MD5 (boost_1_60_0_b1_rc4.zip) = 90c25c34b64eb6cc88845ec5372938d7 Thanks! -- The release managers
