Hello Mr. Mincoin,
Yes, new release candidates have been posted in the Mincoin Development Forum for testing to ensure the compatibility across platforms as well as to ensure all the things work quite well.
It is simply a transitional update, with new libraries linked into it, to secure OpenSSL and such.
I took the opportunity to rebase against Litecoin when doing the work in order to eliminate cruft from the 0.6.x SandyCohen release and the earlier 0.8.7 Vipah release.
The Alert system has been restored and a testnet has been erected. All of which we can validate as the testing stakeholders bring their nodes online.
The new client will only communicate with peers using the new client as there is a protocol version upgrade to 70002 and a minimum protocol version requirement of 70002.
As a stop-gap until we bring everyone on the same new code; a bridge node is operating to keep the current v60002 peers and the new v70002 peers on the same Best Chain.
Largely, it will be a maintenance release we hope for everyone to adopt.
Then, we'll be able to evaluate who is getting our message, by upgrading and who might be left behind when we do the next Network Upgrade to the v0.10.2.2 Litecoin code which will bring us the BIP66 improvements and then afterwards, v0.10.4.0 which will bring us a BIP65 lock-in too.
After those steps, we can jump ahead to the fun stuff where the inherited build system on the modern Bitcoin/Litecoin code will give us releases for Raspberry Pi.
