Some welcome news from Boost.org...
These open-source libraries work well with the C++ Standard Library, and are usable across a broad spectrum of applications.
The Boost license encourages both commercial and non-commercial use.
This release contains one new library and numerous enhancements and bug fixes for existing libraries.
This is the first release since November of last year, and the last one since Boost migrated from a monolithic Subversion repository to modularized git repositories on github.com. The end users should see no change though, since the archives have the same layout as previous releases.
