I'm proud to announce that I've released the fourth candidate of Boost.Log for the review. There were many improvements since the passed year of development. Many of them reflect the discussion of RC3. Here's a short list of major changes: * Substantial documentation improvement. The tutorial section has been reorganized. * Removed rotating file stream. As a replacement, a new file sink has been added, which allows to achieve the same results ans adds a few more features. It is now possible to collect rotated log files in a dedicated directory. * Added a new multifile sink backend. * Added a new ordering asynchronous sink frontend. * The syslog sink backend is now supported on Windows, too. The sink no longer requires native support for POSIX API for syslog, but is able to send syslog packets to a remote server over UDP. * Added support for scoped logging. There is now a distinct log record entity, which is returned by the core as a result of filtring. * Added support for exception control. * Added a new mode of logging, called trivial logging.
