Hi there, we (the Boost maintainers) intend to bump boost to a more recent version in course of Fedora 18 development. Though no schedule is available for Boost or Fedora as of yet, it seems like we are aiming for 1.50 and there should be a couple months of overlap. We intend to make this a feature when our plans become more solid, as usually. One of the more invasive changes that this release will probably bring is getting rid of support for Boost.Filesystem v2 [1], which was already announced about two Fedoras ago. I'd like to encourage all maintainers who build their packages with -DBOOST_FILESYSTEM_VERSION=2 to drop that option and try to rebuild their packages as soon as possible, ideally before the new Boost lands. Thanks, PM P.S. thanks to Denis Arnaud who spotted the intention of removal!
