+`BUGFIX: Disable content element wrapping and inline editable for references in content reference list <https://github.com/neos/neos-development-collection/pull/4399>`_
+------------------------------------------------------------------------------------------------------------------------------------------------------------------------
+
+The NeosUI tries to initialize the inline editor for rendered references in content reference list. But they are not accessable at this moment. As references shouldn't get edited anyways, we can simple disable the content element wrapping for these references.
+
+Fixes https://github.com/neos/neos-ui/issues/3574

+`BUGFIX: Disable publish checkmark for new pages in workspace <https://github.com/neos/neos-development-collection/pull/4277>`_
+-------------------------------------------------------------------------------------------------------------------------------
+
+closes `#3991 <https://github.com/neos/neos-development-collection/issues/3991>`_
+
+**Review instructions**
+If the document is new, I show a small disabled checkmark instead of the functioning checkmark. This will force the user to use the checkboxes on the left side to publish changes. 
+This does not solve the underlying problem but it will at least disable the function for Editors.

+--------------------------------------------------------------------------------------------------------------------------
+
+The PositionalArraySorter implementation allows string values for the position of nodetypes, tabs, groups and views since a long time but the schema validation showed warnings.
+
+**Review instructions**
+
+Open the ``NodeTypes`` tab in the ``Configuration`` module with the Neos.Demo and the previous validation warnings shouldn't show up anymore.

+------------------------------------------------------------------------------------------------------------------------------

+Currently, its not possible to use the shorthand
+```yaml

+        hasFoo:
+          type: boolean
+          # ui: {} # this must be set to an empty array

+-----------------------------------------------------------------------------------------------------------
+
+closes cross repo issue: https://github.com/neos/neos-ui/issues/3483
+
+In the UI it will be once https://github.com/neos/neos-ui/pull/3507 is merged possible to use the ``hidden`` property in the node creation dialog
+
+```yaml
+ui:
+  creationDialog:
+    elements:
+      hiddenProperty:
+        type: string
+        ui:
+          hidden: true
+```
+
+This change adjusts neos creationDialogPostprocessor so that creationDialog items that are generated from properties via ``showInCreationDialog`` will have the hidden property copied
+
+```yaml
+properties:
+  hiddenProperty:
+    type: string
+    ui:
+      showInCreationDialog: true
+      inspector:
+        hidden: true

+`TASK: add default value for generatorName at kickstart command in SiteKickstarter <https://github.com/neos/neos-development-collection/pull/4214>`_
+----------------------------------------------------------------------------------------------------------------------------------------------------
+
+We tried to reproduce #4053.
+We can't reproduce this issue, but while reproducing we found a flow command prompt, without a default value.
+
+The command ``flow kickstart:site AnySite.Site`` asks for a site generator.
+We added a default value by adding: 
+```php
+array_key_first($selection)
+```

Should we use ``array_key_last`` too or is ``array_key_first` fine for it?

+Now use "myString" in documentation, because the return value is a string and not an array. This can lead to confusion under certain circumstances.
