Nextcloud Server 29.0.0 → 35.0.1
49 versions, 28 critical-change sections in 5 versions (2 repeat an earlier entry), 6 required stops
Required stops
- 29.0.16
Latest 29.x release.
Nextcloud must be upgraded step by step:
- Before you can upgrade to the next major release, you need to upgrade to the latest point release of your current major version.
- Then run the upgrade again to upgrade to the next major release’s latest point release.
- You cannot skip major releases. Please re-run the upgrade until you have reached the highest available (or applicable) release.
- Example: 18.0.5 -> 18.0.11 -> 19.0.5 -> 20.0.2
Wait for background migrations to finish after major upgrades. After upgrading to a new major version, some migrations are scheduled to run as a background job. If you plan to upgrade directly to another major version (e.g. 24 -> 25 -> 26) you need to make sure these migrations were executed before starting the next upgrade. To do so you should run the
cron.phpfile 2-3 times, for example:$ sudo -E -u www-data php -f /var/www/nextcloud/cron.phpSource: https://docs.nextcloud.com/server/latest/admin_manual/maintenance/upgrade.html (checked 2026-09-26)

Web server configuration
Make sure that your web server is serving files with the webp extension (WebP images) correctly as static assets. This is included in the shipped .htaccess file but if you use another web server or custom configuration you need to check this manually.

blacklisted_filesis now deprecated and replaced withforbidden_filenames - The option
forbidden_charsis now deprecated and replaced withforbidden_filename_characters - The option

Automated clean-up of app password
Nextcloud 30 will clean-up unused app passwords.
Critical change
Monitoring: Counting of active users
Starting with Nextcloud 30.0.12 the monitoring app was adjusted to count the active users in the same way as occ user:report and the support app.
Critical change
AppAPI (app_api) is now a default app
Starting with Nextcloud 30.0.1, the AppAPI app is included and enabled by default. See ExApps management for details.
You can disable this app in the standard manner via the Apps menu if you do not expect to use AppAPI integrations in the near future.
If AppAPI is disabled, other apps that depend on it will not be visible in the app store. AppAPI-related setup checks will also be deactivated.

- PHP 8.4 is now supported, but 8.3 is recommended.
Critical change
Database configuration
Other row formats than DYNAMIC for MySQL and MariaDB databases will issue a warning since Nextcloud 24, as they often cause performance issues. With Nextcloud 31 a more prominent new setup warning for this was added.
The row format can be changed via ALTER TABLE DDL commands during a maintenance window. Changing the row format from COMPRESSED to DYNAMIC requires about 2x the disk space and may take a long time depending on the size of the database. See the MySQL documentation for more information. If you're not sure how to do this, you can find some tips and tricks from the community.
Critical change
PHP configuration
We have a new setup warning to check if the memory reserved for APCu is high enough. If you see this warning, you should increase the memory reserved for APCu. You can do this by increasing the value of the apc.shm_size directive in your php.ini file. It is generally advised to review this value and increase it if necessary depending on your instance size.
Critical change
Nextcloud configuration
Maximum chunk size
We have adjusted the default maximum chunk size for big file uploading. Previously it was set to 10MiB, it is now increased to 100MiB.
Also the configuration was moved from an app configuration to the system configuration (config.php). If you set up a custom value previously the value will be automatically migrated to the system configuration during the update. But if you need to set a new custom value you need now to use the system configuration, see also Adjust chunk size on Nextcloud side.
Critical change
Monitoring: Counting of active users
Starting with Nextcloud 31.0.6 the monitoring app was adjusted to count the active users in the same way as occ user:report and the support app.
Critical change
Previews
Starting with Nextcloud 31.0.10, the preview provider for MP3 files, which reads cover images embedded in the files, is disabled by default for performance and stability reasons. See Previews configuration for details on how to enable or disable the preview provider.

Critical change
Web server configuration
- Setup checks do not check for the
X-XSS-Protectionresponse header anymore. It has been removed from Nextcloud's.htaccessand you may want to adjust your webserver config to not serve it anymore. XSS filtering was supported only until Chromium 78 and similarly old browsers, but had been found to cause more issues, including attack vectors, than it solved. Nowadays, aside of not serving the header at all, the only generally recommended value is0. More context can be found in the OWASP Cheat Sheet Series.
Critical change
Monitoring: Counting of active users
The monitoring app was adjusted to count the active users in the same way as occ user:report and the support app.
Critical change
System address book
During the upgrade to Nextcloud 32 the system address book might become disabled if the amount of system users exceeds the default limit of 5000 users. This is to prevent performance issues. You can re-enable the system address book using the command line or administration interface.
For more information about the system address book, see the documentation. System Address Book
Critical change
Previews
Starting with Nextcloud 32.0.1, the preview provider for MP3 files, which reads cover images embedded in the files, is disabled by default for performance and stability reasons. See Previews configuration for details on how to enable or disable the preview provider.
Critical change
AppAPI (app_api) setup checks expanded
Starting with Nextcloud 30.0.1, the AppAPI app is included and enabled by default. See ExApps management for details. Additionally, as of version 32.0.0, the AppAPI has expanded its setup checks.
You can disable this app in the standard manner via the Apps menu if you do not expect to use AppAPI integrations in the near future.
If AppAPI is disabled, other apps that depend on it will not be visible in the app store. AppAPI-related setup checks will also be deactivated.
Critical change
S3 integrity protections enabled, configuration update may be needed
The AWS SDK for PHP was updated and now supports the data integrity protections for S3.
>= Nextcloud 32.0.2: If your S3 backend does not support the data integrity protection, you can disable it by adding 'request_checksum_calculation' => 'when_required', and 'response_checksum_validation' => 'when_required', to the object store configuration.
>= Nextcloud 32.0.3: S3 data integrity protections are disabled by default and are now opt-in.
If your S3 backend does not support this, you may see an error such as Checksum Type mismatch occurred, expected checksum Type: null, actual checksum Type: crc32 in your logs when uploading files.
More details about data integrity protections for S3 can be found at https://docs.aws.amazon.com/sdkref/latest/guide/feature-dataintegrity.html and https://github.com/aws/aws-sdk-php/discussions/3100.

You can also configure any other URL to use in the configuration instead. See Connections to remote servers.
Critical change
Previews
The preview provider for MP3 files, which reads cover images embedded in the files, is disabled by default for performance and stability reasons. See Previews configuration for details on how to enable or disable the preview provider.
Critical change
Snowflake IDs
This version of Nextcloud ships with Snowflake IDs. Those IDs include the creation time of object, a sequence ID and a server ID. The server ID should now be configured in your config.php file or using environment variables. See Configuration Parameters for more information.
Critical change
OpenMetrics endpoint
Nextcloud 33 introduces a /metrics endpoint that can be integrated into every OpenMetrics (Prometheus) system. For security, it only answers on localhost by default.
See Monitoring for more information about it.
Critical change
Default user agent for outgoing requests changed
Starting with this release, the default user agent for requests done by the instance was changed from Nextcloud Server Crawler to Nextcloud-Server-Crawler/X.Y.Z, where X.Y.Z is the current server version.
Critical change
TaskProcessing worker command
Previously we instructed admins to run occ background-job:worker <JobClass> to speed up AI task processing. This recommendation has changed to running occ taskprocessing:worker, which handles parallel execution better. Make sure to update your setup.
