Software versions of OpenWrt/LEDE release, packages, etc.
Steps to reproduce
"opkg install zip" renders the following error: Unknown package 'zip'.
It is available until 18.06.
The reason one needs good old zip package, because one can created a compressed and encrypted file collection, that can easily be send by email to different devices and can easily be read by Windows, MacOS, Linux, Android, iphone, etc. It is not the best at anything it does, but because it is so old, it is widely supported.
Package can't be built in buildbot. (some obscure name collision despite the package rename.)
The package built in private environments compiled wrongly and was unusable with most targets.
Package has been removed from master.
