--- Comment #13 from oiaohm oiaohm@gmail.com --- Jerome Leclanche "Bumping to major since it's a regression on wine behaviour itself and a backwards-compatibility issue affecting lots of use cases."
Its also Windows Application Compadiblity issue. UNC paths and / acceptance under Windows. That windows applications are allowed to accept.
Problem is I cannot see that the usage cases cannot be address by shell script wrappers so avoiding the UNC issues. Yes documentation update not a patch to wine.
The question is it major code fix or major documentation fix.
