Yes, the > symbol changed to an arrow in menu paths. Once you do the find and replace, you'll need to select each arrow and change the character style to OOoComputer Code. This changes the font to Liberation Mono and makes the arrow centered. There was not a centered arrow in Liberation Sans.
The formatting for tables has changed.
You'll need to check the links. Some go to the OOo site. For example the extensions link in Ch. 1 of the Writer Guide, the new link is in Ch. 1 of Getting Started.
You're right in you're latest email, the chapter title references have changed slightly.
One thing that I'm not sure of at the moment is the discussion that's going on about doing screenshots under windows. From what they are saying, the screenshots may have to be done under Linux. So for the moment, you might want to hold off on doing much work on those until there is a clearer answer on how to move forward. I don't want us to do a bunch of work that will have to be changed. Maybe someone else on the lists can help.
The status for the Feedback column will stay No until the chapter is ready to move to the Proofing stage. Only if it gets to Proofing and someone sees something that needs to be changed does it need the Back status. When you check something out, you don't need to change the status of the Feedback, Proofing or Publish until you're done with that part of the work or have reviewed it and noticed that it either needed more work or agree that it is ready to be published. If it's checked out again for more editing after in Back status, you're ID is enough. You don't really need to change the status until you're ready for it to go to Proofing again.
