[OpenWrt-Devel] OpenWrt 19.07.0 second release candidate

[Hauke Mehrtens]

Hi,

The OpenWrt community is proud to announce the second release candidate
of the upcoming OpenWrt 19.07 stable version series. It incorporates 126
commits since the previous release candidate 19.07.0-rc1.

With this release, the OpenWrt project brings all supported targets back
to a single common kernel version and further refines and broadens
existing device support. It also provides initial support for the new
ath79 target, the future device tree based successor of the popular
ar71xx target. For 19.07, both targets are still built, but it is
recommended to switch to the ath79 target whenever possible: future
releases of OpenWrt will drop support for the ar71xx target. Please read
the known issues below before upgrading.

---

Changes in this release candidate since the previous 19.07.0-rc1 release
candidate are:

 * Linux kernel updated to versions 4.14.156 (from 4.14.151 in
   v19.07.0-rc1)
 * GCC update to version 7.5.0 (from 7.4.0 in v19.07.0-rc1)
 * Hostapd update to version 2.9
 * Device support bugfixes for many devices
 * Security fixes for curl, e2fsprogs, expat, wolfssl, intel-microcode
 * Sysupgrade bugfix for an issue that could cause sysupgrade to
   silently fail to upgrade on ar71xx devices
 * Added support for the following devices: YunCore XD4200 and A782,
   TP-Link Archer C60 v1/v2, ALFA Network Quad-E4G and R36M-E4G,
   AVM FRITZ!Repeater 1200
 * Disable image generation for several devices due to insufficient
   flash space for the default set of packages. Images can still be
   built with the help of the ImageBuilder or SDK with a more minimal
   set of packages

When upgrading from 19.07.0-rc1, if you are affected by the sysupgrade
bug on ar71xx, you need to manually edit /lib/upgrade/stage2 and add
/usr/share/libubox/jshn.sh to list of files in the install_file line
(around line 51). This amounts to manually applying this patch:

Known issues:

 * Sysupgrade from ar71xx to ath79 and vice versa is not officially
   supported, a full manual reinstall is recommended to switch targets
   for devices supported by both ar71xx and ath79
 * 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 in the
   forum and consider downgrading to OpenWrt 18.06 or using the Image
   Builder to pack a smaller custom image
 * Some optional GUI packages crash with an error about missing
   "cbi.lua", install the luci-compat package to fix these
 * Possible Wi-Fi issues with ath10k-based boards. If you encounter such
   an issue, please file a bug report against openwrt-19.07.
