How do I check my gedit version? [duplicate]

I want to install some plugins for gedit, and I need to know my gedit version to install the correct plugins. How do I check it?

Note: I'm running Ubuntu 16.04

Alternative to the desktop version: command line it would be...

$ gedit --version
gedit - Version 3.22.1

For version it's Help > About and you should get this:

You can use apt to get any package's version:

$ apt list --installed gedit
gedit/stable 3.22.0-1

or dpkg:

$ dpkg -l gedit
||/ Name              Version        ...
+++-==========================================
ii  gedit             3.22.0-1       ...

For more info about the version number:

man deb-version
