Updates for iOS are released through the iTunes software, and, since iOS 5, via over-the - air software updates . With the announcement of iOS 5.0 on June 6, 2011, a USB connection to iTunes was no longer needed to activate iOS devices; data synchronization can happen automatically and wirelessly through Apple's iCloud service . Major new iOS releases are announced yearly during the Apple Worldwide Developers Conference (WWDC), and are usually released in September of the same year, usually coinciding with the release of new iPhone models . The current stable release, iOS 11.4, was released on May 29, 2018 . </P> <Table> Current versions <Tr> <Th> Version </Th> <Th> Build </Th> <Th> Processor support </Th> <Th> Application support </Th> <Th> Kernel </Th> <Th> Release date </Th> <Th_colspan="5"> Device end - of - life </Th> </Tr> <Tr> <Th> iPad </Th> <Th> iPhone </Th> <Th> iPod Touch </Th> </Tr> <Tr> <Td> 3.1. 3 </Td> <Td> 7E18 </Td> <Td> 32 - bit ARM </Td> <Td> 32 - bit ARM </Td> <Td> 32 - bit </Td> <Td> 000000002010 - 02 - 02 - 0000 Feb 2, 2010 </Td> <Td> N / A </Td> <Td> 1st gen </Td> <Td> </Td> </Tr> <Tr> <Td> 4.2. 1 </Td> <Td> 8C148 </Td> <Td> 000000002010 - 11 - 22 - 0000 Nov 22, 2010 </Td> <Td> N / A </Td> <Td> 3G </Td> <Td> </Td> </Tr> <Tr> <Td> 5.1. 1 </Td> <Td> 9B206 </Td> <Td> 000000002012 - 05 - 07 - 0000 May 7, 2012 </Td> <Td> 1st gen </Td> <Td> N / A </Td> <Td> </Td> </Tr> <Tr> <Td> 6.1. 6 </Td> <Td> 10B500 </Td> <Td> 000000002014 - 02 - 21 - 0000 Feb 21, 2014 </Td> <Td> N / A </Td> <Td> 3GS </Td> <Td> </Td> </Tr> <Tr> <Td> 7.1. 2 </Td> <Td> 11D257 </Td> <Td> 32 / 64 - bit ARM </Td> <Td> 32 / 64 - bit ARM </Td> <Td> 32 / 64 - bit </Td> <Td> 000000002014 - 06 - 30 - 0000 Jun 30, 2014 </Td> <Td> N / A </Td> <Td> </Td> <Td> N / A </Td> </Tr> <Tr> <Td> 9.3. 5 </Td> <Td> 13G36 </Td> <Td> 000000002016 - 08 - 25 - 0000 Aug 25, 2016 </Td> <Td> 2, 3, Mini 1 </Td> <Td> 4S </Td> <Td> 5 </Td> </Tr> <Tr> <Td> 10.3. 3 </Td> <Td> 14G60 </Td> <Td> 000000002017 - 07 - 19 - 0000 Jul 19, 2017 </Td> <Td> </Td> <Td> 5, 5C </Td> <Td> N / A </Td> </Tr> <Tr> <Td> 11.4 </Td> <Td> 15F79 </Td> <Td> 64 - bit ARM </Td> <Td> 64 - bit ARM </Td> <Td> 64 - bit </Td> <Td> 000000002018 - 05 - 29 - 0000 May 29, 2018 </Td> <Td> N / A </Td> <Td> N / A </Td> <Td> N / A </Td> </Tr> <Tr> <Td_colspan="10"> <Table> <Tr> <Th> Legend: </Th> <Td> Discontinued </Td> <Td> Current </Td> <Td> Beta </Td> </Tr> </Table> </Td> </Tr> </Table>
