**General Fixes:**

- Device connectivity handling has been rewritten which resolves lot of issues (e.g. devices staying in Disconnected-state).
- Fixed lots of stability issues.
- Fixed localization functionality. Now user specific language selections are set and restored correctly.
- Fixed potentially higher than needed user privileges issue triggered by BMDE 3.10 installation.
  - All BMDE users should install the new version or run the uninstaller included in the 4.0 installation image if they have already removed BMDE application from their system manually.

**Known issues:**

- BMDE for Mac application bundle is not yet using notarization. i.e. in some cases user may need to install package using Open-action from package context -menu / two-finger tap -menu.
- During testing a few unexpected BMDE MacOS crashes were detected (not reproduced):
  - When saved edited BMDE iOS settings.
  - And when custom workflow with ”take picture” feature was run.
- It's possible to setup both primary and secondary printers but only one printer can be used for label printing at once.
- Label size is not detected automatically, correct size must be set in BMDE printer settings.
- There are few known situations when duplicate device cards might appear:
  - e.g. After failed erasure when device gets automatically connected back in recovery mode or if changing port for device during firmware download. Reconnecting the device or re-login should remove the duplicate cards.
- With Catalina macOS there’s issue with finder popup window that gets displayed once erasure is started.
  - Erasure continues normally and popup window(s) can be closed once displayed.
- Every now and then highlight effect does not work in Erasure view and e.g. cancel button might not be visible.
  - To fix that take focus outside the BMDE MacOS for a short moment (e.g. using cmd+tab keys).
