Compatibility
Converting LS3 to LS4
When updating to LS4 the current custom Question Themes will be updated into the LS4 standard. If the Theme has missing attributes that can not be automatically inserted, they will not be installed and instead be available for installation. If an error occurs they can be found under #Broken Question Themes. If you want to import a Question Theme from LS3 into LS4 after you have updated your Installation you can simply use the #Importing Question Theme which has an integrated functionality to automatically convert it.
Importing a Question Theme from LS4 into LS3 is not automatically possible.
LS4 changes
The "custom_attributes" tag is not needed anymore. Attributes will allways be defined inside the attributes tag instead. There is no need for different naming since they will be merged together when reading the Question Type.
Further there has been addistions to the metadata section of the xml, additions are marked in red. File:QuestionThemes12Compatibility.png
