The OpenWrt Community is proud to announce the fourth service release of the stable OpenWrt 18.06 series. OpenWrt 18.06.4 incorporates a number of bug fixes in the network and system userland, as well as updates to the kernel and base packages.

Note that the OpenWrt 18.06.3 release was skipped in favor to 18.06.4 due to a last minute 4.14 kernel update fixing TCP connectivity problems which were introduced with the first iteration of the Linux SACK vulnerability patches.

Some selected highlights of the service release are:

Linux kernel updated to versions 4.9.184/4.14.131 (from 4.9.152/4.14.95 in v18.06.2)

SACK security fixes for the Linux kernel

WPA3 security fixes in hostapd

Further security fixes for Curl and the Linux kernel

MT76 wireless driver updates

Various network and system service fixes

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

Have fun!
