Now that Wine 3.0 has been released, Wine is in regular development
again and Wine 3.1 is the first snapshot. It includes the following
changes:

• Kerberos authentication support.
• Window class redirection for Common Controls 6.
• Support for X11 ARGB visuals.
• DOSBox is required for running DOS executables. (This is enabled via the existing DOSBOX option.)
• Various bug fixes.

As some functionality moved from the Wine Staging tree, so have some
files that now install by default (and are thus no longer contingent
on the STAGING option).
