The OpenWrt Community is proud to announce the ninth service release of the stable OpenWrt 18.06 series. OpenWrt 18.06.9 brings security fixes, as well as the usual device support fixes and core components update.

The main highlights of this service release are:

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 18.06.9 or a newer major release whenever possible.

  • libubox: Fix regression that could cause procd to fail to start or restart some services. This is especially visible as it broke LuCI when upgrading from older 18.06.X releases (FS#3177)
  • musl: fix locking synchronization bug
  • kernel: backport out-of-memory fix for non-Ethernet devices
  • firewall: fix TCP MSS clamping that was only applied on one direction (FS#3231)
  • brcm63xx: fix BCM6348/BCM6358 hangs while booting (FS#2202)
  • ipq40xx: fix essedma MAC hang by disabling TCP segmentation offload for IPv6
  • ramips: fix USB detection on all rt305x devices
  • mikrotik: add support for the new ath9k caldata encoding (LZO) found in newer hardware revisions
  • Various fixes for ZyXEL Keenetic, ZyXEL NBG6616, TP-Link Archer C60 v1/v2, GL.iNet GL-AR750S, Embedded Wireless Dorin, Pirelli A226M-FWB, Arduino Yun
  • Linux kernel updated from 4.9.214 to 4.9.243 and from 4.14.171 to 4.14.206
  • mbedtls updated from 2.16.4 to 2.16.8
  • wireguard updated from 0.0.20190601 to 1.0.20200611

For more details, please see the detailed Changelog.

Note that updates to the package feeds are available immediately to all minor releases of OpenWrt: there is no need to upgrade to a new OpenWrt image to install newer versions of a package. This applies to core OpenWrt packages as well as community-maintained packages.

As always, a big thank you goes to all our active package maintainers, testers, documenters, and supporters.

Have fun!
