title: How can I disable WordPress plugin updates?
body: <p>I've found a great plugin for WordPress under GPLv2 license and made a lot of changes in source code, plugin does something else now.
  I modified author (with original plugin author's credits), URL, version number (from xxx 1.5 to YYY 1.0).</p>
  <p>Everything works great, but when WordPress checks for plugin updates it treats my plugin YYY 1.0 as xxx 1.0 and displays notification about available update.</p>
  <p>My changed plugin YYY 1.0 was installed by copying files from my computer, not from WP repository.</p>
  <p>What else do I have to change?</p>
