Upgrading from TWiki-4.1.0

Download the upgrade package as either zip or tgz. The upgrade package contains all files that changed since 4.1.0.

To make it easy for all - the upgrade package is a zip or tgz file with the files placed in the same directories as a normal twiki installation. Simply copy the files on top of the existing files. Great care has been taken not to alter files you would normally have changed as part as normal tailoring so in most cases you can safely upgrade from 4.1.0 to 4.1.1 in less than 1 minute.

ALERT! Note that 4.1.1 changes the default directory for session files from /tmp to /tmp/twiki. You will need to create this directory and make sure that the apache server have access rights to write files in this directory. This is done to enhance security.

On Unix/Linux you may need to re-apply the correct file access rights to the replaced files. See SettingFileAccessRightsLinuxUnix for a quick way to do this in general.

The following files have been removed in 4.1.1:

and can safely be deleted after upgrading.
