Mojang announces a "whole new version of Minecraft they are calling Minecraft: Windows 10 Edition Beta (though they'll probably drop the beta part at some point), an update for the sandbox mining and construction game. They currently plan on releasing this on July 29th, and they reassure the 20-some million owners of the Java-based PC edition that they are entitled to a free copy of the new version, while everyone else can purchase it for USD $10.00 while it is in beta. Here's word:

We have exciting news to share! A whole new version of Minecraft is on its way. This time, it’s for Windows 10 – Microsoft’s new swanky operating system that’s due for release on July 29th.

We’re calling it Minecraft: Windows 10 Edition Beta.

Just like the first release of Minecraft all those years ago, this version will develop and evolve over time with the help of your feedback. That’s why it has “Beta” in the title – because it’s not quite finished, and will become even more fun over time. Just like the other versions of Minecraft, all future updates will be free. We spoil you. We really do.

If you’re one of the 20 million(!) players who have the PC edition of Minecraft (referred to by techy people as the Java version) you’ll be able to download Windows 10 Edition Beta from the Windows 10 store for free. Other players can get it for the paltry price of $10 during the beta period (the length of which is still being decided).

Minecraft is available on Windows, Mac, Windows Phone, iOS, Android, Xbox 360, Xbox One, PS3, PS4 and PS Vita, and now, Windows 10. Not every version of Minecraft is exactly the same, but they all feature two distinct game modes – Creative and Survival – that cater to different types of players. All versions of Minecraft support multiplayer.

You’ll recognise some Pocket Edition features in Minecraft: Windows 10 Edition Beta, along with potpourri of cool extras. Here are some highlights:

• Craft, create, and explore online with up to seven friends playing Windows 10 Edition Beta, through local multiplayer or with your Xbox Live friends online.
• Play online and local multiplayer with other Pocket Edition players thanks to a free update, due to arrive soon after launch.
• Multiple control schemes! Switch between controller, touch, and keyboard controls with little to no effort!
• Record and share gameplay highlights with built-in GameDVR.
• Help shape the future of Minecraft: Windows 10 Edition Beta with our built player feedback mechanisms!
• Chickens, zombies, pigs, boats, armed skeletons, potatoes, zombies, baby squids, enchantment tables, villagers, naked sheep, iron golems, potions, ghasts, pickaxes, carrots, and all the weird and wonderful goodness you’ve come to expect from Minecraft.

We hope you’re as excited as us for Minecraft: Windows 10 Edition Beta. It’s gonna be cool!
