Apple has issued a new 77.5MB update for iTunes just days after releasing its previous version of the music library software.

Although Apple updated iTunes to 10.2 on Wednesday last week, it’s seen fit to release a second one, urging users to now upgrade to 10.2.1.

Apple hasn’t detailed why in the update notes.

However, it is required in order to install Apple’s new iOS update (4.3) for the iPhone, iPod touch and iPad, which Apple says will land on 11 March.

That confirmation hasn't, however, stopped some sites believing that Apple will release the software update earlier. Pocket-lint is sceptical though.

The company has also issued an update for Java for Mac OS X 10.6. Update 4, "delivers improved compatibility, security, and reliability by updating Java SE 6 to 1.6.0_24," says Apple. 

You can download both updates in the usual ways.
