Upgrades directly to 5.1.2 will work fine. For example, if you upgrade directly from Collage 5. 1.0 to 5.1.2, the upgrade will complete correctly. Also, upgrading from a full install of Collage 5.1.1 to 5.1.2 will complete correctly.
To edit Collage assets via the Web Development and Versioning (WebDAV) interface, Macromedia Dreamweaver MX and UltraDev must connect to the Collage Server using an HTTP version 1.0 port. Because the Tomcat application server which is included with Collage no longer uses HTTP version 1.0 for Solaris or Linux, the HTTP 1.0 connection is provided via a separate port rather than the main Tomcat port. For Windows this is not an issue since the HTTP 1.0 port is enabled by default.
LDAP: Depending on the configuraiton on the LDAP server, users may have been forced to log into Collage twice every time. When this happens, the Tomcat log would show error "Bean: OpenProject: <project name> com.merant.ldap.LdapException".
