| This release provides initial support for the new ''ath79'' target, the future device tree based successor of the popular ''ar71xx'' target. For 19.07, both targets are still built, but it is recommended to switch to the ''ath79'' target whenever possible: future releases of OpenWrt will drop support for the ''ar71xx'' target. | This release provides initial support for the new ''ath79'' target, the future device tree based successor of the popular ''ar71xx'' target.

See the [[docs:techref:targets:ath79|ath79 technical reference]] for rationale about the transition. |

| Please read the known issues below before upgrading. | To perform the upgrade, please follow the instructions from [[docs:guide-user:installation:ar71xx.to.ath79|Upgrading from ar71xx to ath79]]. Functionality for a given device should be equivalent between the two targets: if this is not the case, please [[:bugs|report the issue]] and revert back to ar71xx if needed. |

| With this step, Lua usage in LuCI is reduced and LuCI effectively comes closer to the goals of the experimental [[docs:techref:luci2|LuCI2]] without having to rewrite everything from scratch. | With this step, Lua usage in LuCI is reduced and LuCI effectively comes closer to the goals of the experimental [[docs:techref:luci2|LuCI2]] without having to rewrite everything from scratch. |

| * Sysupgrade from ''ar71xx'' to ''ath79'' and vice versa is not officially supported, a full manual reinstall is recommended to switch targets for devices supported by both ''ar71xx'' and ''ath79'' | Here is a selection of known issues with 19.07.0: |
| | |
| | * Sysupgrade from ''ar71xx'' to ''ath79'' and vice versa is not officially supported and will not work on all devices, please see [[docs:guide-user:installation:ar71xx.to.ath79|Upgrading from ar71xx to ath79]]. |
| | * Several devices that are supported in ''ar71xx'' are not yet supported in ''ath79'': this is a community effort. Helping to port devices to ''ath79'' to make them available in future 19.07.X releases is very welcome. |
| * Images for some device became too big to support a persistent overlay, causing such models to lose configuration after a reboot. If you experience this problem, please [[https://forum.openwrt.org/t/19-07-report-devices-here-that-cant-save-settings/48046/2?u=tmomas|report the affected device in the forum]] and consider downgrading to OpenWrt 18.06 or using the Image Builder to pack a smaller custom image | * Images for some device became too big to support a persistent overlay, causing such models to lose configuration after a reboot.
