A new beta build is available at: http://www.toadworld.com/Downloads/ToadforDataAnalysts/tabid/186/Default.aspx .
The following does not apply if you have not installed any of the 2.5 beta builds prior to 18.104.22.1680.
Settings from any of the previous 2.5 beta builds will not be migrated. The default application data directory has been changed beginning with beta 22.214.171.1240. The default location has been changed to C:\Documents and Settings<your Windows login ID>\Application Data\Quest Software\Toad for Data Analysts Beta 2.5". This change was made to facilitate ease of installation in Citrix environments. You can manually copy the settings files to the new directory if you have made significant customizations. You will still be prompted to migrate settings from installed trial or commercial releases.
The list of fixes and enhancements can be found in the release notes: http://www.toadsoft.com/tda/ToadforDataAnalystsRNBeta.htm .
