Confluence 1.3.6 is a maintenance release which fixes a number of issues users may encounter when using Confluence 1.3 with an Oracle database. It is intended for those customers who are not yet ready to upgrade to Confluence 1.4.
Confluence 1.3.6 is a free upgrade for any existing Confluence customer. If you're not a Confluence customer, we recommend you try our free trial of Confluence 1.4.1. Also don't forget we offer free licenses to registered non-profit organisations and qualifying open source projects.
