An update to version 8.8.2 is available for Notepad++. This is also a security update that fixes CVE-2025-49144. This vulnerability only affects the installer, so anyone who already has Notepad++ installed is not affected.

A yellow UAC popup may appear during installation. This is because the previous certificate has expired and hasn't been replaced yet. Therefore, various antivirus programs may trigger alerts. There have been fixes and improvements, and quite a few of them.

Fixes and improvements:

• Fixed regression causing folding state not to persist across sessions.
• Fixed regression in "Go To Settings" links within Style Configurator introduced in v8.8.
• Fixed minor regression affecting tab background highlighting on hover after drag-and-drop operations.
• Fixed unresponsive (hang) issue related to hidden lines.
