This is the first release of the 6.1 beta.
The web browser view has been updated to a modern web browser standard. Previously for the Windows version, Sparkbooth used Internet Explorer web browser component for this. Many web sites, like SmugMug, Flickr, and Tumblr, are no longer supporting Internet Explorer. With this update, you will be able to sign into those web services without opening an external web browser. The new web view browser also has the benefit of signing out of Facebook and other services much faster.
The Mac version of Sparkbooth for this update is now 64-bit. With the upcoming MacOS Catalina release, 32-bit applications will no longer work on Mac.
Please download and give this beta a try and let me know if you find any issues.
Stay tuned for more updates and features.
