Features

• N/A

Bug Fixes

• Fixed a bug which could cause the application to trigger a restart when initialization or startup is paused or delayed

• Corrected documentation to include configuration file parameters for the improved certificate URL settings from v1.3.3.

Note

• Custom certificate URL setting is now optional
