Poynter's Vicki Krueger shares some news from the American Copy Editors Society conference that will rock copy editors to their very cores: AP Stylebook editors said at a session Thursday that "Over" is fine when referring to a quantity; you don't have to change it to "more than."

The news elicited a gasp, Krueger reports.

Here's the explanation from AP Stylebook Editor Darrell Christian, via Erin Madigan White, AP senior media relations manager:

“We decided on the change because it has become common usage. We’re not dictating that people use ‘over’ – only that they may use it as well as ‘more than’ to indicate greater numerical value.”

Last year AP changed style on underway, a move that caused what's sure to be minor dismay in comparison.

In April of 2012, they loosened up on the use of "hopefully."
