The OpenWrt community is proud to announce the newest stable release of the OpenWrt 22.03 stable version series. It fixes security issues, improves device support, and brings a few bug fixes.

Download firmware images via the Firmware Selector or directly from our download servers:

• Download firmware image for your device (firmware selector)
• Download firmware images directly from OpenWrt download servers

An upgrade from OpenWrt 21.02 or 22.03 to OpenWrt 22.03.2 is supported in many cases with the help of the sysupgrade utility which will also attempt to preserve the configuration. A configuration backup is advised nonetheless when upgrading to OpenWrt 22.03. (see “Upgrading” below).

The OpenWrt Project is a Linux operating system targeting embedded devices. It is a complete replacement for the vendor-supplied firmware of a wide range of wireless routers and non-network devices. See the Table of Hardware for supported devices. For more information about OpenWrt project organization, see the About OpenWrt pages.

  • See 2022-10-17-1

  • ZyXEL NWA50AX / NWA55AXE (ramips)
• ramips/mediatek: backport NAND flash driver from master
• mpc85xx: p1010: make TP-Link WDR4900 v1 build again

• busybox: nslookup: Fix wrongly dropped DNS response on some platforms

• Update rpcd from 2022-08-24 to 2022-09-21
• Update ucode from 2022-08-29 to 2022-10-07
• Update firewall4 from 2022-09-01 to 2022-10-14

Sysupgrade can be used to upgrade a device from OpenWrt 21.02 or 22.03 to 22.03.2 and configuration will be preserved in most cases.

Sysupgrade from 19.07 to 22.03 is not supported.

There is no migration path for targets that switched from swconfig to DSA. In that case, sysupgrade will refuse to proceed with an appropriate error message:
Image version mismatch. image 1.1 device 1.0 Please wipe config during upgrade (force required) or reinstall. Config cannot be migrated from swconfig to DSA Image check failed

• Boot hang with firewall4 and loadfile: When using a firewall configuration declaring config ipset sections in conjunction with an option loadfile entry, the fw4 process will hang and prevent the system startup to complete. To solve this issue, boot the system into failsafe mode and temporarily disable any loadfile option. Proceed with a normal system reboot, upgrade the firewall4 package to version “2022-10-18-7ae5e14b-1” or later using opkg update; opkg upgrade firewall4 and re-enable any previously disabled option loadfile entries.
