|

|
|
The :file:`appinfo/info.xml` contains metadata about the app. A detailed documentation can be found at the `app store documentation <https://nextcloudappstore.readthedocs.io/en/latest/developer.html#info-xml>`_.
|
|
|
|
The info.xml is validated using an XML Schema which can be accessed `online <https://apps.nextcloud.com/schema/apps/info.xsd>`_.
|
|
|
|
A minimum valid **info.xml** would look like this:
|
|
|
|
.. code-block:: xml
|
|
:caption: appinfo/info.xml
|
|
|
|
<?xml version="1.0"?>
|

.. _app changelog:
|
|
|
|
Changelog
|
|
---------
|
|
|
|
Apps can provide a changelog. This should be written in the `keep a changelog <https://keepachangelog.com/>`_.
|
|
|
|
If the apps provide a ``CHANGELOG.md`` file in the project root, this file will be used to show changes for the released version in the app store and for administrators in the app settings.
|
|
|
|
Moreover, since Nextcloud 29, if the ``updatenotification`` app is enabled, apps can also provide a changelog for the users.
|
|
The app will notify users about after the app update if either a ``CHANGELOG.language.md`` (where ``language`` is the language code of that user) or a fallback ``CHANGELOG.en.md`` is available.
|
