I'm just wondering what prompted the major version increment for 4.0.
From what I am seeing there are only cosmetic improvements mostly:
[li]media library view improvement[/li]
[li]visual improvements for plugin installation[/li]
[li]language selection upon install voiding the need for manual wp-config.php editing[/li]
[li]editor visual resizing[/li]
[li]TinyMCE interaction improvements[/li]
[li]small change to widget grouping[/li]
and [li]some changes to some formatting functions[/li][/ul]
Not really anything that would warrant a "version four" to be honest. But I'm sure I'm missing something here...? Is it just a cumulative milestone - I once read that PHP 5 was a renaming of some PHP 4 version because they considered the new features considerable enough to warrant a major version increment. But that doesn't seem to be the case here....
Not seeing any structural changes or anything to become enthusiast about really?
