Here is the Isadora 2.5 advance beta. (The actual version number is 2.4.5b09.) Do not use this for real productions! You should assume that this is beta software and that it will crash! The official release will be announced near the end of September 2016
Important Note For Windows Users: Before installing this version of Isasdora, you should uninstall any previous version. To uninstall Isadora, go to Programs and Features (if your Control Panel is in Category view, go to Uninstall a Program), click Isadora to select it, and then click Uninstall.
