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.

- It looks like boost/version.hpp hasn't been updated for 1.68. It still has two instances of "67" in it, which seem to be cause the auto-linking features for visual studio to look for *-1_67.lib files, while the ones generated are *-1_68.lib. This is present in all four archive formats. Showstopper.

- Tests for Windows/Visual Studio builds failed for msvc-10.0 in program options:

Minor, but causes a build failure for a popular library. Worth fixing before moving on.


Everything else seems to have built correctly.

Compile means that the b2 command completed without errors
Link means that visual studio was able to link a sample executable to a library (libboost_thread-vcXXX-mt[-gd]-1_XX.lib)
generated
Execute means that the linked program executed without errors.
