Upgrade to Nextcloud 28
|
|
=======================
|
|
|
|
System requirements
|
|
-------------------
|
|
|
|
* PHP 8.3 is now supported, but 8.2 is recommended.
|
|
|
|
|
|
Web server configuration
|
|
------------------------
|
|
|
|
* The recommended :ref:`nginx configuration<nginx-config>` changed as Nextcloud Talk now serves audio files with ``.ogg`` / ``.flac`` extension, make sure to add these extensions to the list of static files.
|
|
* As some core app now make use of JavaScript modules, make sure your web server is not rewriting requests to ``.mjs`` files, but serves them with ``text/javascript`` MIME type and proper ``Cache-Control`` header, like ``.js`` and other static file extensions.
|
|
|
|
* When using Apache with ``.htaccess`` configuration, this will be done automatically.
|
|
* For Nginx, please refer to our recommended :ref:`Nginx configuration<nginx-config>`.
|
|
* For other setups, make sure to add ``.mjs`` to the list of static file extensions in web server configs and in case define its MIME type in ``/etc/mime.types``.

Monitoring
|
|
----------
|
|
|
|
Beginning with Nextcloud 28, the monitoring endpoint no longer provides information about available app updates, as gathering the data always involves at least one external request to apps.nextcloud.com.
|
|
|
|
You can still ask the monitoring endpoint to show new app updates by using the URL parameter skipApps=false. However, please do not check this endpoint too often.

Previews for Office files using LibreOffice
|
|
-------------------------------------------
|
|
|
|
Nextcloud can generate previews for Office files using LibreOffice.
|
|
|
|
Since Nextcloud 28, you can also create previews for EMF files.
|
|
To enable it, add ``'OC\Preview\EMF'`` to ``enabledPreviewProviders``.
|
|
|
|
|
|
Until Nextcloud 28, the same LibreOffice user profile was used to generate the previews. LibreOffice can only be invoked once per user profile, so the generation of a preview for an office file would fail if another one were created right now.
|
|
|
|
Beginning with Nextcloud 28, a different LibreOffice user profile is used for each file. Downside: If you upload 100 emf files, you may end up with 100 LibreOffice
|
|
invocations. Though, you can use ``preview_concurrency_new`` and ``preview_concurrency_all`` to limit the number of previews that can be generated concurrently when php-sysvsem is available.
|
|
|
|
The configuration option ``preview_office_cl_parameters`` was removed with Nextcloud 28.
|
|
We expect LibreOffice to be started with the given parameters, so it's unfavorable to have a configuration option to change the parameters.
|
|
Please reach out to us via https://github.com/nextcloud/server/pull/41395 if that's causing any trouble for you.
|
|
|
|
|
|
.. tip:: Previews for EMF files can be enabled without a local LibreOffice installation if you are already using Nextcloud Office / Collabora. Make sure you have Nextcloud Office 8.3.0 installed and add ``'OCA\Richdocuments\Preview\EMF'`` to ``enabledPreviewProviders``. |
