[Freeswitch-users] Git checkout failed

Hi, list! I try to update my freeswitch to stable version 1.2. According to FS Wiki (http://wiki.freeswitch.org/wiki/Installation_Guide#Selecting_version) I applied this command in previos crated freeswitch.git directory: git checkout v1.2.stable But system returned me this error: error: pathspec 'v1.2.stable' did not match any file(s) known to git. What did I do wrong? -- Best regards, Vitaly.
