`BUGFIX: Fusion Array.keys() on null if documentNode doesnt exist in GlobalCacheIdentifiers <https://github.com/neos/neos-development-collection/pull/3837>`_
-------------------------------------------------------------------------------------------------------------------------------------------------------------

https://neos-project.slack.com/archives/C050C8FEK/p1657807863902929

For example when using Fusion in an ajax request, with cache enabled - but no documentNode provided as context, then the calculation of the GlobalCacheIdentifiers fails due to the Eel helper beeing incorrectly used.

`BUGFIX: Check for Imagick in DocumentThumbnailGenerator <https://github.com/neos/neos-development-collection/pull/3783>`_
--------------------------------------------------------------------------------------------------------------------------

The ``DocumentThumbnailGenerator`` will now (again) check for
Imagick being the configured driver in ``canRefresh()``. If the
``imagick`` PHP extension is available and should  be used even
though Imagick is _not_ the driver for Imagine, a new feature flag
can be turned on:

```yaml
Neos:
  Media:
    thumbnailGenerators:
      Neos\\Media\\Domain\\Model\\ThumbnailGenerator\\DocumentThumbnailGenerator:
        # if set, the DocumentThumbnailGenerator will be used when possible, even if the
        # used Imagine driver would usually prohibit it's use (because GD doesn't do PDF)
        overrideImagineDriverCheck: true
```

If reading the source fails without an exception, an exception is
raised and passed on from the ``refresh()`` method. This e.g.
happens when the security policy of ImageMagick denies reading
PDF files.

* See: `#3678 <https://github.com/neos/neos-development-collection/issues/3678>`_

**Review instructions**

To have ImageMagick deny reading of PDF, as is needed to check this, the policy must be changed to include

    <policy domain="coder" rights="none" pattern="PDF" />

- the policy is usually in a place like ``/etc/ImageMagick-6/policy.xml``
- for Local Beach it's inside the ``php`` container in ``/opt/flownative/php/build/extensions/imagick/policy.xml``. To be able to edit it, you must use ``docker exec -u root -it yourproject_php /bin/bash`` to become ``root`` inside the container.

`BUGFIX: Adds missing documentation <https://github.com/neos/neos-development-collection/pull/3819>`_
-----------------------------------------------------------------------------------------------------

In Neos 7.0 we introduced the  ``PropertyValue`` filter for node migrations. With this change, we extend the documentation as well.

**Review instructions**

Please proofread the documentation change.

`TASK: Continue on error in ThumbnailGeneratorStrategy <https://github.com/neos/neos-development-collection/pull/3828>`_
------------------------------------------------------------------------------------------------------------------------

This makes the ``ThumbnailGeneratorStrategy`` continue with the next
available thumbnail generator in case ``refresh()`` failed. This allows
for a "fallback" to be used in case thumbnail generation fails.

Errors are logged to aid with debugging and if all generators fail
another separate error is logged.

See `#3678 <https://github.com/neos/neos-development-collection/issues/3678>`_ for some background info.
