The Litecoin Foundation has raised enough funds to support two full-time developers for about 1 year. The newest unaudited financial statements can be found at https://litecoin-foundation.org/2017/06/financial-statements-2017-06-01/ and the donation list https://litecoin-foundation.org/donation/.
We’ve got Shaolinfry and will probably hire one more shortly, which will be announced once we complete the paper work. Highly skilled full-time developers are very important to Litecoin’s progress, and more support and talents are still needed.
We are going to release 0.13.3rc1 soon. The code can be found at https://github.com/litecoin-project/litecoin/tree/0.13.
Lightning Network/RSK teams are in close contact with the Litecoin team.
