ownCloud 9.0 Release Notes¶
Changes in 9.0¶
9.0 requires .ico files for favicons. This will change in 9.1, which will use .svg files. See Changing favicon in the Developer Manual.
Home folder rule is enforced in the user_ldap application in new ownCloud installations; see User Authentication with LDAP. This affects ownCloud 8.0.10, 8.1.5 and 8.2.0 and up.
The Calendar and Contacts apps have been rewritten and the CalDAV and CardDAV backends of these
apps were merged into ownCloud core. During the upgrade existing Calendars and Addressbooks
are automatically migrated. As a fallback for failed upgrades or an option to test a migration
dav:migrate-calendars
and/or dav:migrate-addressbooks
scripts are available via the
occ
command. See Using the occ Command.
Updates on systems with large datasets will take longer, due to the addition of checksums to the oC database. See https://github.com/owncloud/core/issues/22747.
Linux packages are available from our official download repository .
New in 9.0: split packages. owncloud
installs ownCloud plus dependencies, including Apache
and PHP. owncloud-files
installs only ownCloud. This is useful for custom LAMP stacks, and
allows you to install your own LAMP apps and versions without packaging conflicts with ownCloud.
See Preferred Linux Installation Method.
New option for the ownCloud admin to enable or disable sharing on individual external mountpoints (see Mount Options). Sharing on such mountpoints is disabled by default.
Enterprise 9.0¶
owncloud-enterprise
packages are no longer available for CentOS6, RHEL6,
Debian7, or any version of Fedora. A new package,
owncloud-enterprise-files
, is available for all supported platforms. This
new package comes without dependencies, and is installable on a larger number of
platforms. System administrators on these older distros must install their own
LAMP stacks and databases. On newer supported distros, install
owncloud-enterprise
as usual. See
Installing & Upgrading ownCloud Enterprise Edition.
Changes in 8.2¶
New location for Linux package repositories; ownCloud admins must manually change to the new repos. See How to Upgrade Your ownCloud Server
PHP 5.6.11+ breaks the LDAP wizard with a ‘Could not connect to LDAP’ error. See https://github.com/owncloud/core/issues/20020.
filesystem_check_changes
in config.php
is set to 0 by default. This
prevents unnecessary update checks and improves performance. If you are using
external storage mounts such as NFS on a remote storage server, set this to 1
so that ownCloud will detect remote file changes.
XSendFile support has been removed, so there is no longer support for serving static files from your ownCloud server.
LDAP issue: 8.2 uses the memberof
attribute by default. If this is not
activated on your LDAP server your user groups will not be detected, and you
will see this message in your ownCloud log: Error PHP Array to string
conversion at /var/www/html/owncloud/lib/private/template/functions.php#36
.
Fix this by disabling the memberof
attribute on your ownCloud server with
the occ
command, like this example on Ubuntu Linux:
sudo -u www-data php occ ldap:set-config "s01" useMemberOfToDetectMembership 0
Run sudo -u www-data php occ ldap:show-config
to find the correct sNN
value; if there is not one then use empty quotes, ""
. (See
Using the occ Command.)
Users of the Linux Package need to update their repository setup as described in this blogpost.
Changes in 8.1¶
Use APCu only if available in version 4.0.6 and higher. If you install an older version,
you will see a APCu below version 4.0.6 is installed, for stability and performance
reasons we recommend to update to a newer APCu version
warning on your ownCloud admin page.
SMB external storage now based on php5-libsmbclient
, which must be downloaded
from the ownCloud software repositories (installation instructions).
“Download from link” feature has been removed.
The .htaccess
and index.html
files in the data/
directory are now
updated after every update. If you make any modifications to these files they
will be lost after updates.
The SabreDAV browser at /remote.php/webdav
has been removed.
Using ownCloud without a trusted_domain
configuration will not work anymore.
The logging format for failed logins has changed and considers now the proxy
configuration in config.php
.
A default set of security and privacy HTTP headers have been added to the
ownCloud .htaccess
file, and ownCloud administrators may now customize which
headers are sent.
More strict SSL certificate checking improves security but can result in “cURL error 60: SSL certificate problem: unable to get local issuer certificate” errors with certain broken PHP versions. Please verify your SSL setup, update your PHP or contact your vendor if you receive these errors.
The persistent file-based cache (e.g. used by LDAP integration) has been dropped and
replaced with a memory-only cache, which must be explicitly configured. See
User Authentication with LDAP. Memory cache configuration for the
ownCloud server is no longer automatic, requiring installation of
your desired cache backend and configuration in
config.php
(see Configuring Memory Caching.)
The OC_User_HTTP backend has been removed. Administrators are encouraged to use
the user_webdavauth
application instead.
ownCloud ships now with its own root certificate bundle derived from Mozilla’s root certificates file. The system root certificate bundle will not be used anymore for most requests.
When you upgrade from ownCloud 8.0, with encryption enabled, to 8.1, you must enable the new encryption backend and migrate your encryption keys. See Encryption migration to ownCloud 8.0.
Encryption can no longer be disabled in ownCloud 8.1. It is planned to re-add this feature to the command line client for a future release.
It is not recommended to upgrade encryption-enabled systems from ownCloud Server 8.0 to version 8.1.0 as there is a chance the migration will break. We recommend migrating to the first bugfix release, ownCloud Server 8.1.1.
Due to various technical issues, by default desktop sync clients older than
1.7 are not allowed to connect and sync with the ownCloud server. This is
configurable via the minimum.supported.desktop.version
switch in
config.php
.
Previews are now generated at a maximum size of 2048 x 2048 pixels. This is configurable
via the preview_max_x
and preview_max_y
switches in config.php
.
The ownCloud 8 server is not supported on any version of Windows.
The 8.1.0 release has a minor bug which makes app updates fail at first try. Reload the apps page and try again, and the update will succeed.
The forcessl
option within the config.php
and the Enforce SSL
option
within the Admin-Backend was removed. This now needs to be configured like
described in Use HTTPS.
WebDAV file locking was removed in oC 8.1 which causes Finder on Mac OS X to mount WebDAV read-only.
Enterprise 8.1 Only¶
The SharePoint Drive app does not verify the SSL certificate of the SharePoint server or the ownCloud server, as it is expected that both devices are in the same trusted environment.
ownCloud 8.0¶
Manual LDAP Port Configuration¶
When you are configuring the LDAP user and group backend application, ownCloud may not auto-detect the LDAP server’s port number, so you will need to enter it manually.
No Preview Icon on Text Files¶
There is no preview icon displayed for text files when the file contains fewer than six characters.
Manually Migrate Encryption Keys after Upgrade¶
If you are using the Encryption app and upgrading from older versions of ownCloud to ownCloud 8.0, you must manually migrate your encryption keys. See Encryption migration to ownCloud 8.0.
Windows Server Not Supported¶
Windows Server is not supported in ownCloud 8.
PHP 5.3 Support Dropped¶
PHP 5.3 is not supported in ownCloud 8, and PHP 5.4 or better is required.
Disable Apache Multiviews¶
If Multiviews are enabled in your Apache configuration, this may cause problems with content negotiation, so disable Multiviews by removing it from your Apache configuration. Look for lines like this:
<Directory /var/www/owncloud>
Options Indexes FollowSymLinks Multiviews
Delete Multiviews
and restart Apache.
ownCloud Does Not Follow Symlinks¶
ownCloud’s file scanner does not follow symlinks, which could lead to infinite loops. To avoid this do not use soft or hard links in your ownCloud data directory.
No Commas in Group Names¶
Creating an ownCloud group with a comma in the group name causes ownCloud to treat the group as two groups.
Hebrew File Names Too Large on Windows¶
On Windows servers Hebrew file names grow to five times their original size after being translated to Unicode.
Google Drive Large Files Fail with 500 Error¶
Google Drive tries to download the entire file into memory, then write it to a temp file, and then stream it to the client, so very large file downloads from Google Drive may fail with a 500 internal server error.
Encrypting Large Numbers of Files¶
When you activate the Encryption app on a running server that has large numbers of files, it is possible that you will experience timeouts. It is best to activate encryption at installation, before accumulating large numbers of files on your ownCloud server.
Enterprise 8.0 Only¶
No Federated Cloud Sharing with Shibboleth¶
Federated Cloud Sharing (formerly Server-to-Server file sharing)does not work with Shibboleth .
Direct Uploads to SWIFT do not Appear in ownCloud¶
When files are uploaded directly to a SWIFT share mounted as external storage in ownCloud, the files do not appear in ownCloud. However, files uploaded to the SWIFT mount through ownCloud are listed correctly in both locations.
SWIFT Objectstore Incompatible with Encryption App¶
The current SWIFT implementation is incompatible with any app that uses direct file I/O and circumvents the ownCloud virtual filesystem. Using the Encryption app on a SWIFT object store incurs twice as many HTTP requests and increases latency significantly.
App Store is Back¶
The ownCloud App Store has been re-enabled in oC 8. Note that third-party apps are not supported.
ownCloud 7 Release Notes¶
Manual LDAP Port Configuration¶
When you are configuring the LDAP user and group backend application, ownCloud may not auto-detect the LDAP server’s port number, so you will need to enter it manually.
LDAP Search Performance Improved¶
Prior to 7.0.4, LDAP searches were substring-based and would match search attributes if the substring occurred anywhere in the attribute value. Rather, searches are performed on beginning attributes. With 7.0.4, searches will match at the beginning of the attribute value only. This provides better performance and a better user experience.
Substring searches can still be performed by prepending the search term with
“*”.For example, a search for te
will find Terri, but not Nate:
occ ldap:search "te"
If you want to broaden the search to include
Nate, then search for *te
:
occ ldap:search "*te"
Refine searches by adjusting the User Search Attributes
field of the
Advanced tab in your LDAP configuration on the Admin page. For example, if your
search attributes are givenName
and sn
you can find users by first name
+ last name very quickly. For example, you’ll find Terri Hanson by searching for
te ha
. Trailing whitespaces are ignored.
Protecting ownCloud on IIS from Data Loss¶
Under certain circumstances, running your ownCloud server on IIS could be at risk of data loss. To prevent this, follow these steps.
In your ownCloud server configuration file, owncloud\config\config.php
, set
config_is_read_only
to true.
Set the config.php
file to read-only.
When you make server updates config.php
must be made writeable. When your
updates are completed re-set it to read-only.
Antivirus App Modes¶
The Antivirus App offers three modes for running the ClamAV anti-virus scanner:
as a daemon on the ownCloud server, a daemon on a remote server, or an
executable mode that calls clamscan
on the local server. We recommend using
one of the daemon modes, as they are the most reliable.
“Enable Only for Specific Groups” Fails¶
Some ownCloud applications have the option to be enabled only for certain groups. However, when you select specific groups they do not get access to the app.
Changes to File Previews¶
For security and performance reasons, file previews are available only for image files, covers of MP3 files, and text files, and have been disabled for all other filetypes. Files without previews are represented by generic icons according to their file types.
4GB Limit on SFTP Transfers¶
Because of limitations in phpseclib
, you cannot upload files larger than
4GB over SFTP.
“Not Enough Space Available” on File Upload¶
Setting user quotas to unlimited
on an ownCloud installation that has
unreliable free disk space reporting– for example, on a shared hosting
provider– may cause file uploads to fail with a “Not Enough Space Available”
error. A workaround is to set file quotas for all users instead of
unlimited
.
Zero Quota Not Read-Only¶
Setting a user’s storage quota should be the equivalent of read-only, however, users can still create empty files.
Enterprise 7 Only¶
No Federated Cloud Sharing with Shibboleth¶
Federated Cloud Sharing (formerly Server-to-Server file sharing) does not work with Shibboleth .
Windows Network Drive¶
Windows Network Drive runs only on Linux servers because it requires the Samba client, which is included in all Linux distributions.
php5-libsmbclient
is also required, and there may be issues with older
versions of libsmbclient
; see Using External Storage > Installing and
Configuring the Windows Network Drive App in the Enterprise Admin manual for
more information.
By default CentOS has activated SELinux, and the httpd
process can not make
outgoing network connections. This will cause problems with curl, ldap and samba
libraries. Again, see Using External Storage > Installing and Configuring the
Windows Network Drive App in the Enterprise Admin manual for instructions.
Shibboleth and WebDAV Incompatible¶
Shibboleth and standard WebDAV are incompatible, and cannot be used together in ownCloud. If Shibboleth is enabled, the ownCloud client uses an extended WebDAV protocol
No SQLite¶
SQLite is no longer an installation option for ownCloud Enterprise Edition, as it not suitable for multiple-user installations or managing large numbers of files.
No App Store¶
The App Store is disabled for the Enterprise Edition.
LDAP Home Connector Linux Only¶
The LDAP Home Connector application requires Linux (with MySQL, MariaDB, or PostgreSQL) to operate correctly.
