Hello
I am missing some great features that have been present in either uMod or OxideMod.org

- The ability to see what was updated in a plugin, the author would write a short sentence or whatever about what they have updated in a plugin.
- Direct link to Github page for the plugin

Why can't we see this anymore? It is vital to staying up to date imo

You see more than I do then...
I only see Documentation and Updates tab

Updates tab has the version history and any updates other than the original version posted here. This is the same as how it worked on the old site.

IF the author decides to link it to GitHub, it will show a GitHub link, otherwise they are not using GitHub with it. Authors/maintainers are not required to link to GitHub, this is there as an option to them. This is the same as how it worked on the old site.

What Garbage Collector posted above is what resource authors see, not users. Those are the options for linking GitHub if they desired and such.
