Ahead of the release of iOS 9 set for tomorrow, Apple has started updating its iOS apps beginning with improvements and fixes for its iWork suite of iOS apps.

All three apps— Pages, Numbers, and Keynote—get an update today with “stability improvements and bug fixes,” many of which are likely related to the iOS 9 update arriving tomorrow. 

iOS 9 will officially arrive Wednesday, September 16th, for the iPhone 4s and later, iPod touch 5th generation and later, iPad 2 and later and iPad mini and later. The release follows Apple’s new iPhone 6s and 6s Plus going up for pre-order earlier this month and comes ahead of an official retail launch for the device on September 25th. Following the first weekend of pre-oreders, Apple said this week that it’s on pace to beat its previous opening-weekend record of 10 million units.

We’d expect that other Apple apps will get a similar treatment too alongside the release of iOS 9 tomorrow.
