[wp-testers] Issue with version_compare()

[Kim Parsell]

I'm reworking my plugin, and need to use version_compare() in order to 
serve up the correct code to users of either 2.9 or 3.0.

A sample of the code I'm using is:

        if (version_compare($wp_version, '2.9', '=')) {
            // do something here
        } else if (version_compare($wp_version, '3.0', '=')) {
            // do something else
        }

In testing on my 3.0 dev install (single user mode), the code to be 
served to the 3.0 users wasn't executing unless I changed the last part 
from '=' to '<='.

I did a search through Trac and came upon a comment in a ticket 
(http://core.trac.wordpress.org/ticket/13566#comment:12) where someone 
else was having the same issue with the new importers.

My understanding of comment 13 from mdawaffe is that api.wordpress.org 
should now be using everything before the first "-" when comparing 
version strings, so the code I have above *should* work; however, it isn't.

Is the change to the API only available for checking if a new version of 
a plugin is available for download, or should it also work in a plugin 
when doing version_compare(), such as what I'm trying to do?

Thanks in advance!
