• Fixed an issue where the wal directory would fill up with temp files that consumed too much disk space.
• Fixed issue where Chrome browser tab would crash when inactive.

Notes

• Some of the changes with Performance 1.11 require a new profile or a change to the existing profile. For new profiles, create a new one and set it at a higher priority than the other profiles. To edit an existing profile, make a simple change such as modifying the description and then save the profile.
• After you upgrade Performance, you must complete the following steps to see the updated Performance Trends board:
  • If the previous version of the Performance Trends board is installed, delete the existing Performance board.
    • Note: Any customizations made to this board will not be saved. You can also import over the top without deleting and then manually clean up duplicate items
  • After you delete the existing board, import the new Performance board from the Initial Gallery. For more information, see Trends User Guide: Import the gallery.
    • Note: You might see source errors. This is expected, and you can disregard the errors. Click Import to complete the import of the board.
