In the 8 years history of Litecoin, we've only had a handful of core developers working on Litecoin Core.
At various points in time, it's been me, @wtogami, @thrasher_au, @shaolinfry, @TheRealXinxi, and @loshan1212.
We actually did release Litecoin Core 0.17.1 May of this year: blog.litecoin.org/litecoin-core-…
When we release 0.18.1, Adrian will merge his branch into master. When that happens, it would all of a sudden add all the 2019 commits. 😲
