1.1 is the same as 1.0 but packages with format other than MuranoPL/1.0 (or just 1.0) will be rejected by Murano Kilo. As a result it will be possible to specify that application require yaql 1.0 which was introduce in Liberty. MuranoPL/1.2 differs in that it has yaql legacy mode turned off and several functions are now cannot be called as MuranoObject methods. It is recommended to start development of new applications using 1.2 format Change-Id: Ie68cc0c37f198c10eeac79ed349f9d9d420e038f Implements-Blueprint: muranopl-format-version-upgrade
