Apple’s Thunderbolt hardware pieces are coming together and to get ready, Apple is updating MacBook Air firmware. The 4 MB update promises to enhance the stability of Lion Recovery from an Internet connection, and resolve issues with Apple Thunderbolt Display compatibility and Thunderbolt Target Disk Mode performance on MacBook Air (mid 2011) models.

Thunderbolt parts have already began shipping and new products include Docks, external PCI Card adapters, as well as storage.
