New 13-inch MacBook Airs have quietly been upgraded with one of the 15-inch model’s most useful features

It appears that Apple has sneaked in an upgrade for new 13-inch MacBook Airs, adding Bluetooth 5.3 support – matching the capabilities of the recently-released 15-inch MacBook Air.

When the latest model of the 13-inch MacBook Air launched last year, it supported Bluetooth 5.0 – however, some eagle-eyed visitors to Apple’s website have found that the specifications page for the 13-inch model now lists Bluetooth 5.3 (as spotted by MacRumors).
