Get the strange warning

Get the strange warning today:

Warnings:
* Modified plugin file: wp-content/plugins/litespeed-cache/admin/class-litespeed-cache-admin-display.php
* Modified plugin file: wp-content/plugins/litespeed-cache/readme.txt

And really, I found the difference between repository and current versions of Litespeed cache plugin.

I thought, it was because of Disable All Updates plugin, I’m using, which blocks all updates. Si, I thought, your plugin saw this difference and sent the warning to me.

But after checking, I saw, that there is now new updates for Litespeed cache plugin.

So, I don’t understand… There is no update, but there is a difference, but there is no attack notification…
