The OpenWrt community is proud to announce the newest service release of OpenWrt 21.02. It fixes security issues, improves device support, and brings a few bug fixes.

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.

On February 9th 2022, OpenWrt switched to https://github.com/openwrt/openwrt/issues/ for bug tracking.

All bugs have been migrated, and the old service https://bugs.openwrt.ifw.cn has been decommissioned (with redirections to the new service)
