 -----------------------------------------------------
 OpenWrt 18.06.0, r7188-b0b5c64c22
 -----------------------------------------------------

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.

An upgrade from OpenWrt 15.05 or LEDE 17.01 to OpenWrt 18.06 is supported 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 18.06.

Highlights In OpenWrt 18.06.0

The OpenWrt community is proud to announce the first release of the OpenWrt 18.06 stable version series. It incorporates over 4000 commits since branching the previous LEDE 17.01 release and has been under development for well over a year.

With this release, the re-merged OpenWrt project attempts to define a baseline for future development based on the technological modernization and refined release processes done by the former LEDE project.

Highlights of this release since the previous LEDE 17.01 and OpenWrt Chaos Calmer 15.05 versions are:

  • Linux kernel updated to version either 4.9.111 or 4.14.52, depending on the architecture
  • Updated toolchain:
    • musl libc 1.1.19
    • uClibc-ng 1.0.30
    • glibc 2.26+
    • gcc 7.3.0
    • binutils 2.29.1
  • Updated Linux kernel:
    • Kernel 4.9.111 for ar7, ar71xx, arc770, at91, brcm2708, brcm63xx, ixp4xx, lantiq, layerscape, mpc85xx, orion, rb532 and uml
    • Kernel 4.14.52 for apm821xx, archs38, armvirt, ath25, bcm53xx, brcm47xx, cns3xxx, gemini, imx6, ipq40xx, ipq806x, kirkwood, malta, mediatek, mvebu, mxs, octeon, octeontx, omap, oxnas, pistachio, ramips, sunxi and x86
    • Backported network flow offloading support for targets using kernel 4.14
  • Network userland:
    • IPv6 related fixes in DHCPv6 client and servers
    • Support for user DHCPv6 client options in sent packets
    • DHCP forced renew support (RFC6704) in odhcpd
    • Firewall support for conntrack helper setup and better ipset integration
    • Introduced support for configuring GRE, GRE-TAP, VETH, VTI, VXLAN
    • CAKE v20180716 includes tc filter classification making ingress prioritisation easier. Cake & sqm-scripts updated representing state of the art mitigations for bufferbloat
    • Wireguard VPN v20180625 with MIPS optimisations and flow-offload compatibility
  • System userland:
    • Improvements in system upgrade procedure
    • Bugfixes in the process manager, system message bus, embedded webserver and the configuration management library
  • Platform and Driver Support
    • Dropped adm5120, adm8668, au1000, mcs814x, omap24xx, ppc40x, ppc44x, xburst and zynq targets
    • Added Spectre and Meltdown mitigations as well as microcode loading support to x86
    • Rebased oxnas target on top of upstream Kernel 4.14 support
    • Updates and new device support across all targets
  • Web interface:
    • New auto-rollback functionality to revert configuration changes when access to the router is lost
    • Better support for displaying virtual interfaces and low level configuration errors
    • Security improvements

Known issues:

  • Support for a hardware-bug workaround needed for devices having an AT8032 ethernet phy accidentally got dropped. Hence devices with that ethernet chip may experience connectivity issues. At least ubnt-loco-m-xw and most likely other single-port ubnt devices are affected. [fix merged, queued for 18.06.1]
  • Using ip4ip6 tunnel interface as a fallback interface accepting ip4-in-ip6 tunneled packets from any remote address doesn't work. [fix merged, queued for 18.06.1]
  • Support for PCIe on ox820 is broken, results in missing USB3 support on Shuttle KD20 [driver needs more work]
  • 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 report the affected device and consider downgrading to LEDE 17.01.5 or using the Image Builder to pack a smaller custom image
  • Some devices, such as the Netgear R6100, may lack 5GHz wireless AC support. Investigation is ongoing and a fix is expected for 18.06.1. Affected users shall downgrade to LEDE 17.01.5 for the time being and wait for the first service release.
  • Devices using the mt76 wireless driver may experience stability issues on 2.4GHz
  • The legacy at91 and legacy ath25 (formerly “atheros”) targets failed to build due to image size constraints and are not part of the release
  • A GUI bug prevents selecting and scrolling text in the system and kernel log pages. To solve, either upgrade “luci-theme-bootstrap” using opkg or switch to another theme. [fix merged, queued for 18.06.1]

With the release of OpenWrt 18.06, the old OpenWrt 15.05 release is marked end of life and will not get any support any more, not even for severe security problems. LEDE 17.01 will still get some security support for a limited time. We encourage everyone to upgrade to OpenWrt 18.06 to get the best support.

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

Have fun!

The OpenWrt Community
