# Bug fixes

## Client deletion timeout fix

Fixed an issue where attempting to delete a client with an important number of `granted_scopes` would result in a timeout and failure to delete.

## Cache hostname parsing fix

Fixed an issue where provided cache hostnames would be incorrectly parsed when using the newly implemented `cluster` backend.

## Cache unavailability fix

Fixed an issue where cache unavailability could potentially result in performance drops.

## UpgradeHandler synchronization fix

Fixed an issue where initializing the `UpgradeHandler` in different areas of the applications simultaneously would result in argument exception errors.
