Hi miqrogroove, thank you for forwarding the issue to WP trac. I might also add the following:
1. The update notification is NOT persistent, in other words, sometimes it’s there, most other times it’s not.
2. Going through the WP trac change history page, someone suggested that the WP-Security plugin might have something to do with this issue. I do indeed have this plugin active (obfuscation of WP version).
I’ll go ahead and tinker some with the workarounds suggested on WP Trac. Thanks for looking into this.
