Looking at the version history page, I was thinking it could be useful to have an EOL date listed in the table for each version. Is there any reason not to include it on this version history page? AFAICT, you currently have to look for the EOL for old versions in the release notes of newer (but still old) versions...
I see, for example, 15.05 EOL'd with the release of 18.06.0.
With the release of OpenWrt 18.06, the old OpenWrt 15.05 release is marked end of life and will not get any support any more, not even for severe security problems. LEDE 17.01 will still get some security support for a limited time. We encourage everyone to upgrade to OpenWrt 18.06 to get the best support.
Would it be a matter of combing through these release announcements or the devel list to find this info? Or is there a better location to find the list of EOL dates?
