[asterisk-users] What does it mean rc in the release version

[bilal ghayyad]

Hi All;

When I find the "rc" in the release name dahdi-linux-2.2.0-rc5.tar.gz, then what does it mean the "rc5"? 

Which is better, to select dahdi-linux-2.2.0-rc5.tar.gz or to select dahdi-linux-2.1.0.tar.gz? I am afraid that rc means still not finally finished and has bugs?

Any advise?

Regards
Bilal
