We are thrilled to announce the availability of the first public beta of Kaleidoscope 2.1, featuring Whitespace Ignoring, great user interface refinements, and far too many minor enhancements to name in a blog post. We have listened to the input that our loyal users have been sending to us through this last year and brought a lot of those valuable opinions into play when creating this improved version of our app.

Kaleidoscope is one of the world's best tools for spotting differences in images and text. Now it supports the ignoring of leading, trailing and line-ending whitespace too. Kaleidoscope integrates directly with Git, Subversion, Mercurial, P4, and Bazaar to fit perfectly in your workflow.

Development of Kaleidoscope 2.1 required a significant number of changes to the core of the app. We have tested it to our satisfaction but we would like additional help to pass more files through it. We want to ensure everything works as intended before releasing it as an update to everyone. Specifically, here are some areas for which we would love feedback:

  • Whitespace Ignoring : We have put this feature through as many tests as we could think of, but we would like to see more real world documents put through it.
  • General Text Differences : In the process of adding Whitespace Ignoring, we did some heavy modifications of the diff engine in general.
  • Git Integration : Many of you have had issues with the Git integration in Kaleidoscope 2 under Mavericks.

If you spot any text diffs that look odd, issues with whitespace ignoring, or anything else that does not seem right, let us know by emailing If possible, please include example files, or at least a screenshot, when reporting diff issues.

We think you are going to love Kaleidoscope 2.1 and you can download the public beta starting today. During the beta phase, the app will not require a registration. You can find out more about Kaleidoscope 2.1 at
