5.4.0

• Fix: changing ContentTypeGroup upon updating ContentType

• Fix: setting custom modification date on Content Create (ticket #173)

• New: it is now possible to create or update a Content setting multiple translations at the same time. Ex:

    -
        type: content
        mode: create
        content_type: myClass
        parent_location: 2
        attributes:
            title:
                eng-GB: hello world in eng-GB
                abc-DE: hello world in abc-DE
  

  Note that in order for the content definition to be considered valid "multi-langauge", ALL attributes values must
  be specified using a language key. The following example is thus invalid:

        attributes:
            title:
                eng-GB: hello world in eng-GB
                abc-DE: hello world in abc-DE
            description: A description to rule them and in the drakness bind them
  

• New: it is now possible to use Symfony Expression language in IF conditions. Ex:

    -
        type: ...
        if:
            "reference:some_id":
                satisfies: "value % 3 == 0"
  

  Here the migration step would only be executed if the Id stored in the reference is divisible by 3.

• New: it is now possible to loop over arrays, achieving the same as a php foreach call. Ex:

    -
        type: loop
        over: { "hello": world, "buongiorno": mondo }
        steps:
            -
                type: reference
                mode: set
                identifier: loopref
                value: "We have found key: [loop:key] and value: [loop:value]"
                overwrite: true
  

  This should be useful f.e. in conjunction with references of type array, introduced in version 5.1
