I work for Cisco Systems and I help manage several Cisco Certification Pages on our IT Social Networking site: www.ciscolearningnetwork.com. We have recently upgraded to 2.5 and it seems we've lost a few very important Features/Functions from a user or admin point of view.
1. Can not see a Preview version before publishing a new wiki document. So you have to publish document to see a fully rendered view. Adds to the Version history.
2. Can not see a side-by-side comparison view of the html (wiki markup in 1.x). You only see a rendered view comparison when viewing the different versions of the document.
3. Titles on Wiki Docs are no longer Dynamically updated. If you go back and change a Wiki Doc Title you will need to manually update the titles to any reference you are pointing to the original document.
Are we the only ones who lost these features/functions moving to 2.5 or is it a customization issue???
