v7.4.1 - Critial Regression More information about the issue: Users are advised to downgrade to v7.3.3: Download v7.3.3 For Users of the portable version of Notepad++ (portableapps.com):
Is this a security issue or just a feature that is broken issue, I see no reason to downgrade if it's not security related, I don't even know what "in replace in files feature" is, doesn't seem to impact my usage at all here.
