[Asterisk-Users] Stable or not?

[Anderson Alves de Albuquerque]

 How can I know if my Asterisk is stable?

 I am using:
----------------------------
# asterisk -V
Asterisk CVS-v1-0-08/03/05-15:21:21
----------------------------

 I read files (Readme, ...) but I don´t find if it is stable or unstable.
