Where has the Replace Text tool gone since update yesterday?

I opened Adobe Reader DC today and thought the toolbar looked different. The Text replace tool has gone (the one with the crossed-out T and the comment bubble beside it)!

I think Reader downloaded an update yesterday.

If I want to replace text (instead of just deleting or inserting, I can still do it manually (by highlighting the text I want to change and typing my changes). However, the changes appear in red and blue, which they didn't do before (text was just blue before).

I've checked the tools available and there's no option for the Text replace tool any more.

Also, the highlight colour has changed - it's now orange instead of yellow. Is this because of the update too?>

Was this meant to happen? I use the Replace text tool a lot. Please can In have it back?
