Microsoft has released a patch update for PowerToys 0.70, which was released just a week ago along with some new PowerToys. However, some bugs were discovered in this release and so a patch was considered important enough to issue an update. It includes all the features from the previous release as well as a number of bug fixes that are listed below.
This is a patch release to fix issues in v70.0 to fix some bugs that we consider important for stability based on incoming rates. See v0.70.0 for full release notes.
Microsoft also added a warning about potentially disabling Mouse Without Borders service mode after upgrading to 0.70.1, the note reads as follows:
Warning: Service Mode in Mouse Without Borders may be disabled after upgrading and will need to be reactivated.
