Is there a Bizagi 10.8 vestion ?

Hi there, I took a look about ws-security in Bizagi and checked that there's support to it only in versions 10.8 and 11. The link I'm referring to is: http://help.bizagi.com/bpm-suite/en/index.html?bizagi_web_services_security.htm If there's a 10.8 version ? Is it stable ? Where could I download it from ? Regards,
