Syslog Watcher 4.8 is a maintenance update of the version 4.7.x. It contains several important bugfixes and internal improvements, but no new features. However, the version number was changed to 4.8 because it has updated copyright information and so that it will comply with the new version numbering scheme.


This update does not contain any new features, so it is available to all licensed users of Syslog Watcher 4.7.x.


The update does not require any changes to the configuration files or the storage format (applies to 4.8.3 or later), so there are no extra actions needed apart from the standard update procedure.
