Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add va_list versions of dw_debug() and dw_messagebox() for use in C++ bindings. dw_vdebug() and dw_vmessagebox() work similarly to the standard library versions. DW::App:Debug() and DW::App:MessageBox() use them for variable arguments.
