My version of Password Safe is v3.18, however, export only allows v1.x or v2
formats. Will v3.18 read v2 formats ok?
I think you have mis-understood the Export menu items.
The options are:
Plain Text <--------------- This is V3 format!
Export to Plain Text is always for the current version. The others are
mentioned specifically as they are the previous versions. If and when we go to
V4 and if this format is different to the current V3, then we will also
mention Export to V3 format explicitly.
