The iPad Software Development Kit (SDK) has now been stripped of its beta status as Apple released the gold master version of the development software today.

iPad SDK 3.2 GM is the new release that all iPad applications must be built on in order for inclusion in the App Store from this point forward.

In an email sent to developers, Apple states, "All members of the iPhone Developer Program can submit their iPad apps to iTunes Connect for review and approval. If you did not submit your app during the initial review period, but upload it by March 31, it will be reviewed but may not make the grand opening of the iPad App Store." 

MacRumors notes that Apple has also just posted the iPad 3.2 Firmware (download link) on their servers. Of course, if you do download it, there's nothing much you can do since only a select few in the world have iPads (hrm... someone with the lucky last name of "Jobs").

Also of interest is the iPad documentation file (download link) that provides this very interesting statement:

"Apple will provide you any iPad OS software updates that it may release from time to time, up to and including the next major iPad OS software release following the version of iPad OS software that originally shipped from Apple on your iPad, for free. For example, if your iPad originally shipped with iPad 3.x software, Apple would provide you with any iPad OS software updates it might release up to and including the iPad 4.x software release. Such updates and releases may not necessarily include all of the new software features that Apple releases for newer iPad models." 

MacRumors notes that this could mean a free upgrade to the 4.x software, but paid upgrades beyond that. Somewhere in the middle of the iPhone and iPod touch upgrade paths. 

In addition to all of the news above, Apple has also posted a page on their developer site where developers can learn all about submitting their iPad applications to the App Store.

As the iPad launch date approaches, stay tuned to Mac|Life as we will be providing you with up-to-date news and information.
