From Open Web Analytics Wiki
This is a bug fix release that fixes a bug found in 1.2.2 that prevents hosts from being logged properly.
Backwards Incompatible Changes
- Old Async Event Handling mode settings that were configured via the settings management screen no longer govern event queueing. You must re-configure OWA using the new config files constants outlined on the event queueing page.
- This is the last release that will support PHP 4.
See the installation page for how to install OWA for the first time.
This release does not contain any database changes from the last release so normal upgrade procedures apply. See the updating page for more details on how to upgrade your existing OWA instance.
