I have checked that the lastest version for SugarCRM CE is 6.5, and Professional is already in V7.7. Does this mean that SugarCRM CE project line is now dead and no progress is going to be included in CE versions?
You are correct, the Community version will not move to 7.7, see the following post by Clint about that topic:

Version 6.5 however is still supported and receives for example security patches and other important updates.
