Apple is breaking with holiday tradition: The company announced early last month that its App Store will continue to review developer submissions over the holidays, welcome news for app developers facing their busiest season.

Previously, an app that needed to release a bug fix or a critical update on Black Friday or during the final hours of Christmas shopping couldn’t push a fix for days. This year, from December 23 to 27, App Store Connect service staff will work a reduced schedule, which means updates will take place, but reviews “may take longer to complete,” the company said.
