Upgraded to WordPress 2.8 Beta 1. So far so good, with only one weird error:
Fatal error: Call to undefined method SearchSpider::_weak_escape()
I traced this to the Search Unleashed plugin. It interferes with several critical operations including the saving of drafts, searching, publishing, etc. I have obviously disabled it in light of this.
As far as actual WordPress bugs I’m most concerned about, it appears they are not going to fix the Ticket Trac issue I reported to them concerning out of order comments when threading is enabled. This does not make sense to me as this is a fairly large problem that is very reproducable.
Comments on the bug report seem to indicate this will require a fairly big change to the comment walker, but still.
Other than that, there is nothing obviously different about the beta. The admin interface is identical with no visual changes at all that I can see. It appears that all of my plugins have surived this upgrade cycle. *crosses fingers*
Haven’t tested Simple LDAP Login yet but I’m hopeful.
