+Subject: [PATCH] common: Disable enum type stream operators for Qt >= 5.14
+
+Starting from version 5.14, Qt provides stream operators for enum
+types, which collide with the ones we ship in types.h. Disable
+Quassel's stream operators when compiling against Qt 5.14 or later.
+
+Add a unit test that ensures that enum serialization honors the width
+of the underlying type.
+
+(original patch trimmed)
