====== Update Check ======

By default [[DokuWiki]] checks a special URL for messages once a day. This message system is used to notify administrators of DokuWiki installations about new releases and [[security]] warnings

The feature needs to contact ''update.dokuwiki.org'' on Port 80 - make sure your firewall allows this. If you dont want this feature, you can disable it with the [[config#updatecheck]] option.

Each message has a unique ID shown in square brackets. Only messages which have a higher ID than the one configured in ''conf/msg'' will be shown. When you upgrade to the release announced in the message, the ''conf/msg'' file will be upgraded as well, suppressing the message. If you don't want to upgrade to an announced release you can simply increase the number in ''conf/msg''.

When [[wiki:install:upgrade|upgrading your installation]], it might happen that DokuWiki continues to show the update message, even though the number in ''conf/msg'' was increased by the upgrade. This is because DokuWiki caches already fetched messages for a day and will only refetch if the last modified timestamp of ''conf/msg'' is higher than the one of the cache file. To stop the outdated update message from showing you can simply wait a day, touch((//touch// is a UNIX command to change a file´s date and time, the so-called "timestamp")) the ''conf/msg'' or delete the ''data/cache/messages.txt'' cache file.
