Speaking of documentation, it has been improved a lot. The usage chapter has been rewritten almost completely; it has gained a couple of tutorials and all the platform-specific details in it have been moved to two new chapters. One of them focuses on explaining those features available only under a specific operating system while the other summarizes multiple portability issues that may arise when using the generic classes. Additionally, a chapter about supported systems and compilers has been added.
There are still two big things missing that shall be worked on in the (very) short term: add a design decisions chapter to the documentation and incorporate asynchronous functionality to the library by using Boost.Asio. This last thing is needed to keep things simple from the user 's point of view (i.e. no threads on his code).
Check out the official announcement for more details.
I guess that this closes SoC for me this year. There are still going to be some changes before Monday but don't expect anything spectacular (I'll be away during the weekend... hopefully ;-). But don't be afraid! Work on this project will continue afterwards!
