From yesterday to today, Apple released two distinct updates.
Boot Camp
Apple has released two separate updates for Boot Camp 5 (1, 2), but the important thing is that it updated a support article (still unavailable in Portuguese) confirming that Macs since 2012 now also support the Windows 10 via Boot Camp 6 which apparently is not yet free for everyone.
Compatible only with OS X Yosemite, Boot Camp 6 includes support for USB 3, USB-C on the new MacBook, Thunderbolt, memory cards, SuperDrive (internal or external), keyboard, trackpad and mouse connected to Macs running Windows 10 .
This other support article (the Portuguese version is slightly outdated) explains, step by step, how to install Windows on a Mac using Boot Camp.
iPod nano
THE 9to5Mac reported that Apple yesterday also released version 1.0.4 of the operating system for iPod nano, which gained new colors recently.
Apple did not release details about the update, so it appears that they are only general bug fixes. It is available directly through iTunes.
