I have been doing so many sudo apt-get update/(dist-)upgrade since yesterday and something happend - so that I am confused now whether I am using still beta or the stable version.

How do I figure that out?

Open a terminal(type "gnome-terminal" on the dash) and type lsb_release -a and if the output is:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04 LTS
Release:    14.04
Codename:   trusty

you are running the stable release and if the output is:

Distributor ID: Ubuntu
Description: Ubuntu Trusty Tahr (development branch)
Release: 14.04
Codename: trusty

(see the development branch) you are running the beta version.

lsb_release -d is enough – Maythux Apr 18 '14 at 8:27
@Ask: Yes, even that would do. – i08in Apr 18 '14 at 8:28

Try with command

update-manager -d 

and find out if you see an Upgrade button.

Or using GUI run Sysinfo (available in the Ubuntu Software Center) and check out the System tab and read the text under Ubuntu.

If there shows Release 14.04 then you are out of beta.

Update to @Jobin answer:

you can just do it with :

lsb_release -d

This will show you the description only
