• Make re-use of cached certificates much more robust (8,1 even more - #684)
• Additional error logging for validation plugins
• Revert back to FileSystem as default validation for backwards compatibility with Apache (#683)
• Fix success message printed as error (#684)
• Better detection of cases where no IIS binding update is needed (specifically for Central SSL bindings)
• Make all new bindings non-IP specific to prevent 'ghost' bindings from appearing that have the potential to break other websites (#94). Note that it's still possible to manually make the binding IP-specific after LEWS creates it and that existing IP-specific bindings will also still be renewed.
