2.2 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 automati-
cally migrated (except when using the the IMAP user backend). As a fallback for failed upgrades, when
using the IMAP user backend or as an option to test a migration dav:migrate-calendars and/or
dav:migrate-addressbooks scripts are available (only in oC 9.0) via the occ command. See Using the
occ Command.
Warning: After upgrading to ownCloud 9.0 and before continuing to upgrade to 9.1 make sure that all of your
and your users Calendars and Addressbooks are migrated correctly. Especially when using the IMAP user
backend (other user backends might be also affected) you need to manually run the mentioned occ migration
commands described above.
Updates on systems with large datasets will take longer, due to the addition of checksums to the oC database.
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.
