Here are the details of the upgrade:

I think your link to Github is about SlimCoin.

It is, and it isn't. Sprouts and Slimcoin share a lot inherited code from their common Peercoin ancestor.

My interest was piqued by the original post:

Currently we are looking for more nodes, someone to fix the warning on the wallet and a response from https://chainz.cryptoid.info/ regarding a new block explorer.

I'd seen that unwelcome warning message message before in Slimcoin and knew there was a crude but effective solution in the Slimcoin code, so I hunted it down.

After some research, I was able to understand that the old block chain, contact the dev error message originated in Peercoins centralised sync checkpoint feature. The problem is that this feature depends on a central server continuing to automatically produce new sync checkpoints, each authenticated with the devs privkey (look for -checkpointkey in the output from typing help on the debug window's command line).

Once I'd worked out what it was all about, I could safely disable the feature and the irrelevant warnings.

And because I believe that if a job's worth doing, it's worth doing well, I made one of my drive-by contributions and:

- upgraded the code to use Qt5 if available
- eliminated a number of compilation warnings
- added a checkpoint from a recent block
- added a copy of the in-wallet block explorer that I used for Slimcoin
- copied the (known to work and edited for Sprouts) Slimcoin build instructions into the README.

and posted the result as a Pull Request to the Sprouts community Github repos:

https://github.com/SproutsCommunityRep/sprouts/pull/1

So, all the changes are laid out in detail in the commits: except for disabling sync checkpointing and adding the explorer, everything else is aimed at addressing compiler warnings.

HTH
