New Release candidate files for 1.59.0 are available at: http://boost.cowic.de/rc/

RC3 should fix the problem with VC14 and MSPDB140.DLL.

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.

I can verify that the fix does work on VC14/64.

The other builds appear to be working as well. Here's the full matrix:

toolset     arch    compile Link    Execute
msvc-8.0    32      X       X       X
msvc-8.0    64      X       X       X
msvc-9.0    32      X       X       X
msvc-9.0    64      X       X       X
msvc-10.0   32      X       X       X
msvc-10.0   64      X       X       X
msvc-11.0   32      X       X       X
msvc-11.0   64      X       X       X
msvc-12.0   32      X       X       X
msvc-12.0   64      X       X       X
msvc-14.0   32      X       X       X
msvc-14.0   64      X       X       X

Compile means that the b2 command completed without errors
Install means that the installers for the respective version were generated
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.
