Amazon has released Kindle for PC and Mac version 1.29.
The What's New screen has the generic "stability improvements and bug fixes." In my quick test of Kindle for PC I did not notice any obvious differences from the previous version.
Because the software has changed I doubt that the
patch from apprenticesakuya to disable KFX will still work on this version. I am curious to learn whether the other workaround to avoid KFX on the Mac will function.
