v6.04.10044 (20 сен 2022)
Version 6.04 brings various usability improvements to CCleaner. In Health Check, the scan now ignores files that were modified less than a minute ago, meaning that, after we've cleaned, the app won’t communicate that a PC is “under the weather” when it’s not!

This release also includes some minor usability tweaks to the new Cleaning Schedule interface. Plus, we have improved our error reporting to get better information if the app crashes, so we can address critical issues sooner.

v6.03.10002 (22 авг 2022)
Giving a PC a regular check-up with CCleaner keeps it running smoothly. In version 6.03, we have updated and expanded our scheduling tools to make it even easier to stay on top of this maintenance.

We’ve redesigned the scheduling interface to make it simpler to set up automatic cleaning in CCleaner Professional. It now notifies you before cleaning starts and then again once cleaning is complete to confirm the results. A handy switch also allows scheduled cleaning to be paused (while keeping the settings saved). Using the free version? Set a reminder to clean instead!

Alongside this change, the interface for Driver Updater has been improved to make it clearer how long a driver update is taking.
