Disable WordPress Update Option

WordPress version 2.3 arrived with the new feature of the update warning message prominently displayed across the admin - as soon as the version was out-of-date, or, more exactly, on release of another full version.

Well and good,  but what if you have 35-40 clients running WordPress…?

It’s not possible to get round to them all in a couple of days. Yes, installations should be kept at 100% security, however, the real world does intrude.

One solution is a disabling plugin. Some report performance issues (serious) with this, so it may need a little tweak here and there.

What would be nice is a simple checkbox in Admin > Options… just to buy a little time…
