The old Inline Editor version allows user just click the content then edit it. The new one will show the toolbar but need to click the Edit button to enable the edit function.

Could I backward to the old Inline Editor behavior, because the new one seems not so user friendly than the old one. 

Does anybody know how to do this?

Got it, thank you....

Could I give a suggestion. How about user can click to edit and the toolbar will appear near the cursor without user confirm. When user end thier edit. They can click outside the red rectangle then the save or cancel toolbar appear near the cursor to let user choose save or not. This can keep the convenient and keep user from error editing data.

Currently, the tool bar always appear in the left top corner. This becomes very inconvent if the content is longer than one screen. Users need to scroll up to the top of the content to save their result. In this case, I think enter the edit page is a better choose to edit the content and show a little nonsense of the edit toolbar here.

Just a suggestion. Because I got this information from a new DNN user even I understand this is a acceptable change. Maybe we should concern about how the new user feel about the using experience. DNN is better than other CMS system because it user friendly. If the end-user feel it's not so user-friendly anymore. DNN will loose the first look of the new user(For example, me. If DNN doesn't so convenient before, it's possible I will try to find other CMS solution for our company before.).
