One of the first checks I made, after upgrading from B2 to B2TR, was the Content Management features.
In the project I'm working on, our primary focus is on news publishing. A score of news editors will have the means to create newspages, based on custom page layouts, with bindings to content types that extend the basic Article Page content type. This gives us the opportunity to automatically approve news articles if certain criteria are met. This all worked in B2, though sometimes a little unstable. It also works in B2TR – unstable 
.
The automatic approval process is based on an eventhandler. It should kick in, when a new item is created or an item is changed and check the moderation status. If the status is 'Pending' and the criteria are met, the status is changed to 'Approved'. This does not happen everytime and I cannot figure out why 
I suspect the eventhandling in SharePoint not to be 100% reliable. Has anyone out there similar experiences?
Another problem I discovered in B2 was the item status after the page has expired, i.e. the Scheduled End Date is reached; then the status is changed from Approved to Draft. This does not seem logical. I would have liked it to change to 'Archived' or something like that. The problem is still there in B2TR.
Even though I still have pending problems, I think the B2TR is performing better, and my Active Directory import and Audience targetting works now
