Asset nodes now have a new field called "properties.duration_seconds". This holds a copy of the duration stored on the referenced video file and stays in sync using eve hooks.
To migrate existing duration times from files to nodes you need to run the following:
./manage.py maintenance reconcile_node_video_duration -ag
There are 2 more maintenance commands to be used to determine if there are any missing durations in either files or nodes:
find_video_files_without_duration
find_video_nodes_without_duration
FFProbe is now used to detect what duration a video file has.

The attachments should now be rendered using `{attachment slug}` instead
of `@[slug]`. The `link` attribute can be specified in the shortcode
(for attachments that support it), rather than in the attachment itself.
The attachment subdocument is now reduced to `{oid: File ObjectID}`, and
nodes without attachments should NOT have an `attachment` property at
all (previously it would be an empty dict). This makes querying for
nodes with/out attachments easier.
The CLI command `upgrade_attachment_schema` can do dry-run and remove
empty attachments:
- Added --go to actually perform the database changes.
- Remove empty attachments, so that a node either has one or more
attachments or no attachments sub-document at all.
The CLI command `upgrade_attachment_usage` converts `@[slug]` to
`{attachment slug}`. It also takes into account 'link' and 'link_custom'
fields on the attachment. After conversion those fields are removed from
the attachment itself.
Simplified maintentance CLI commands that iterate over all projects:
I've moved the common approach (either run on one project or all of
them, skipping deleted ones, giving a message upon dry-run, and showing
duration of the command) to a new _db_projects() function. The new
function is now used by two recently-touched CLI commands; more of them
could be migrated to use this.
