Note: security fixes for most packages can also be applied by upgrading only the affected packages on running devices, without the need for a full firmware upgrade. This can be done with opkg update; opkg upgrade the_package_name or through the LuCI web interface.
Nevertheless, we encourage all users to upgrade their devices to OpenWrt 19.07.6 or later versions whenever possible.

Upgraded ER-X from 19.07.5 to 19.07.6. No issues. Works great.
Amazingly fast response to new security issues! Thank you Developers!
Edit: As of Jan 27 2021 07:30 EST, I upgraded dnsmasq (and only dnsmasq) to 2.80-16.3 after 19.07.6 installation and can also report this is working fine with no issues. I did not notice any issues prior, but it seemed prudent to grab this update given reports of others.
I upgraded from 19.07.05 to this release on my Linksys WRT1900ACS, keeping the configuration. I then installed the additional packages that I had installed with the prior version and rebooted.
I always update without saving settings and then restore a backup
Genuine question - isn't that exactly what happens when you update while saving settings? It takes a backup, updates the firmware, then immediately restores the backup?
Honestly, I am not sure of the exact mechanism used to achieve the preserve settings task. However, the previous settings are applied immediately, which means that an incompatible config could cause it to fail to boot properly or have other issues (this is unlikely for service releases, but major releases do sometimes have substantial changes). In my case, it's a little more complex in that I have extroot and a bunch of packages. So I have some scripts to make my process easier, but it is basically a format and reload type of construct.
