The second release candidate files for 1.56.0 beta 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. The files (and associated md5s) are: MD5 (boost-1_56_0_b1_rc2.7z) = cd6267325a8dadbb82b384c4776ee450 MD5 (boost-1_56_0_b1_rc2.tar.bz2) = b74cd72043b6b2fa16c6690633acb422 MD5 (boost-1_56_0_b1_rc2.tar.gz) = b51810be6737e73a4deee70e84895ca7 MD5 (boost-1_56_0_b1_rc2.zip) = f4ceb73492ae7d9b1843d841498850e5 Since this is the first post-git release, we are expecting some teething pains with this release. Please test extensively. Besides bug fixes the TypeIndex library has been included, and I think that the problems that mjklaim@gmail.com was seeing have been fixed. I would like to post this to SourceForge Thursday night/Friday morning, if possible. Thank you. --The release managers
