Following last week’s general release of iOS 6.1, Apple has now released iOS 6.1.1 beta to developers. The new version includes a number of improvements to Maps for Japan, including improved pronunciation of roads and identification of toll roads during turn-by-turn navigation, direction optimizations, and new indicators and icons for various features such as interchanges, transit systems and location categories.
The beta also adds 3-D buildings for locations such as Tokyo Station, Japan’s Imperial Palace and Tokyo Tower.
It is notably unusual for Apple to release betas to developers for minor iOS versions; for example, both iOS 6.0.1 and 5.1.1 were released directly to the public with no prior betas sent out for developer testing.
It is also worth noting that this beta release does not include an iOS SDK update nor any updates for the Apple TV or iTunes.
