Microsoft announce a change from the maximum 18-months support for Windows 10 Semi-Annual Channel releases. The diagram below is taken from the announcement page (http://bit.ly/2N3kqty) and shows that there is no change to the support duration for Windows 10 Pro or Home, or indeed Office 365 ProPlus, but the September releases for Windows 10 Enterprise and Education will be supported for 30 months. In addition, all currently supported feature updates of Windows 10 Enterprise and Education editions (versions 1607, 1703, 1709, and 1803) will be supported for 30 months from their original release date.
