Just the term, “golden master”, it pretty much sounds awesome.

Per German web site iFun, Apple is said to be internally testing a new beta of iOS 6.1 that is expected to be the golden master build, suggesting the software is nearly ready to be released to the public.

Citing a “reliable source,” the web site reported Friday that the fifth beta of iOS 6.1 is about to be released to developers. The software is said to have gone through “extensive internal testing,” and if all goes well it will be the golden master of the software.

The software is expected to be released to developers either on Friday or potentially on Monday.

Apple began supplying beta builds of iOS 6.1 to its development community in early November. To date, there have been four betas seeded, the most recent arriving in mid-December.

Changes in iOS 6.1 are mostly minor, with the most significant user-facing additions including the ability to purchase movie tickets through Fandango with Siri, and a new prompt that asks users to enter security questions for iCloud when setting up their device for the first time.

For developers, iOS 6.1 includes an enhanced Map Kit framework that will allow third-party applications to search for map-based addresses based on points of interest. For example, a user could search the term “coffee” and the new framework would return the location of local coffee bars along with information about each one.

iOS 6.1 builds released to date have been compatible with the iPhone 5, iPhone 4S, iPhone 4, and iPhone 3GS; fourth-, third-, and second-generation iPad; iPad mini; and fifth-and fourth-generation iPod touch.

Stay tuned for additional details as they become available.
