BleachBit 4.7.0 | BleachBit

Submitted by andrew on Wed, 06/03/2026 - 19:45

BleachBit 4.7.0 is now available! This release brings BleachBit's cleaners up to date with version 6.0.1, adds support for Supermium, and introduces modern CleanerML compatibility features. It includes significant bug fixes for file handling and symlink traversal, performance improvements, and comprehensive translation updates.

This is a special release of BleachBit intended only for Windows XP, Vista, 7, and 8, so users on Windows 10 and 11 and Linux should continue to use BleachBit 6.0.

Demo

The video shows BleachBit 4.7.0 running on Windows XP SP3, and BleachBit cleans Supermium.

Changes since version 4.6.2

New Features

Cleaners on par with BleachBit 6.0.1: Backported CleanerML files from BleachBit 6.0.1, bringing 4.6.x's cleaners up to date. (Vivaldi, LibreWolf, and Zen were not included because the applications require Windows 10.)
Supermium browser: Added a new cleaner for the Supermium web browser.
Modern CleanerML fallback support: Added fallback support for modern CleanerML browser files. Though the cookie manager is not supported, it falls back to deleting the whole cookie jar instead of rejecting the CleanerML file, allowing seamless CleanerML sharing with BleachBit 6.0.
same_user attribute: Added support for the same_user attribute in CleanerML (for Windows 7 and 8), for multi-user systems. For cleaners such as web browsers, it ignores processes running by other users.
Winapp ExcludeKey: Added support for ExcludeKey with REG type in Winapp.

User Interface

Full screen toggle: Enabled users to toggle full screen with F11.
Upgrade notice: Notify users on Windows 10 and later to use a newer version of BleachBit.

Localization

Other changes

Online update notification system will not suggest updating to BleachBit 6.0 on incompatible versions of Windows.
Removed a huge amount of non-Windows code and data.
Updated and pinned Python dependencies.
Verify hashes for downloaded dependencies.
Updated SQLite from 3.43.2 to 3.53.1.

The installers, executables, and libraries are dual signed for maximum compatibility across Windows versions. For Windows XP, we sign with SHA-1 and Authenticode timestamp format (V1). For newer Windows versions, we sign with SHA-256 and RFC-3161 timestamp format (V2).
The uninstaller is now digitally signed.
List of commits

Like BleachBit 4.6.2, BleachBit 4.7.0 includes Python 3.4.4, which was the last version of Python to support Windows XP, 7, and 8. However, Python 3.4.4 is now outdated: for more information, see BleachBit support for older Windows versions.
