Version 1.6.0 is performance and bug fix release.
We have updated the file format to use a packaged based format.
This change requires that your files be updated to the package format and you will be given the choice to do that when you open a 1.5.2 or previous version of an Antetype document.
The change in file format has been introduced to help us tackle a number of bugs related to saving file and file performance, further changes will be made slowly across future releases.
This version drops support for OS X 10.7.x you now need at least 10.8.0 to run Antetype version 1.6.0.
You guys are awesome! Thank you for keeping Antetype so up-to-date. This application is the core application I use for every project and I couldn't imagine using anything else.
