Not a coding bug, but a serious issue that I think deserves reporting here.

Change log says:

[2009-05-12] NEW: multiple-valued fields can now also be created via 'Format value' actions (values separated by \\).

This breaks action script compatibility.

E.g. whereas previously

Format value ARTIST := aaa\\bbb  
Format value COMMENT := %artist%

set Comment to aaa\\bbb, now it is aaa.

Worse, there's no way of escaping this. E.g 'aaa\\bbb' makes no difference.

This is definitely no bug. Sure, it's different behaviour but it's clearly stated in the changelog.

This breakage of script compatibility is not mentioned in the changelog.
