Main changes from OpenWrt 19.07.4

Only the main changes are listed below. see changelog-19.07.5 for the full changelog.

Security fixes

Note: security fixes for most packages can also be applied by upgrading only the affected packages on running devices, without the need for a full firmware upgrade. This can be done with opkg update; opkg upgrade the_package_name or through the LuCI web interface. Nevertheless, we encourage all users to upgrade their devices to OpenWrt 19.07.5 or later versions whenever possible.

Known issues

  • Transition to ath79: some 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 releases is very welcome.
  • Device support: images for some device became too big to support a persistent overlay, causing such devices to lose configuration after a reboot. If you experience this problem, please 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
  • Device support: conversely, certain images for devices with small flash (4 MB) are no longer built for the release
