[wp-hackers] Disabling automatic plugin upgrade for specific plugin?

[Glenn Ansley]

Hi,
If I've made substantial edits to a plugin for a single client's
specific use and I don't want them to ever automatically upgrade it in
the future (or me either for that matter), is that as simple as
changing the plugin's name or are there SVN hooks/externals or
something else that I need to disable?

Thanks,
Glenn Ansley
