No, it is in my plans to use OpenWrt 18.06.2 since its previous version on 18.06 there were big changes, the devices with memory lower than 4Mb are affected since the updates of the packages and the LuCi interface occupy much more space leaving aside the possibility of compiling complete versions, it can only be compiled with certain packages or a light version.
So it happened with the OpenWrt Fork Gargoyle updated to the branch 18.06 and left out the classic TP-LINK 4Mb Flash.
If you want to update you can use this tool that was published within the community
Online ImageBuilder and Upgrade Server
I prefer to compile from scratch since you can delete even more packages that are not necessary. A good compilation of OpenWrt 18.06.2 would be to eliminate all IPv6, OPKG and to place ZRAM and SQM Scripts would be a very basic version but very useful for the majority of domestic users and small offices ...
Maybe I will compile but I will not be able to test it since I do not have TP-LINK routers. If someone has enough or no longer uses a router, I will be pleased to receive it as a donation.
