In my installation of Mantis bugs are often resolved without the 'fixed in version' field set which throws off the change log. I will periodically attempt to find resolved issues with no fixed in version set so I can set it.

Currently the list in the drop down looks like this:

any

2.0
1.0

Notice the two blank lines between "any" and "2.0"? The first one is simply a separator between "any" and the rest of the list of values. The second one actually represents records that have no value set (empty). It's the second blank I'd like to suggest be displayed as '[empty]'. I'm suggesting 'empty' with the square brackets to go along with other special uses like [MySelf].

So the revised drop down would be:

any

[empty]
2.0
1.0

An alternative to using "[empty]" and perhaps a better suggestion would be to put 'empty' as a value under 'any', and then put the separator and the rest of values. For example:

any
empty

2.0
1.0

Thank you for considering this.
