Earlier this week, Apple released its third Public Beta of iOS 10, the next major update to its mobile operating system. The company describes the new version as its biggest iOS release ever, bringing a wide range of new features and improvements to its i-devices.
But the company hasn't ignored the current version of the OS while development on the new edition has continued. After releasing iOS 9.3.3 last month, it's now rolling out a further incremental update in the form of iOS 9.3.4.
The on-device description for 9.3.4 states that it "provides an important security update for your iPhone or iPad and is recommended for all users". Apple elaborates on the nature of the update in a security bulletin on its support site:
Released August 4, 2016
Available for: iPhone 4s and later, iPad 2 and later, iPod touch (5th generation) and later
Impact: An application may be able to execute arbitrary code with kernel privileges
Description: A memory corruption issue was addressed through improved memory handling.
