Dogecoin 1.7.0 Alpha 1

Dogecoin Core 1.7 Alpha

Dogecoin Core 1.7 is a complete re-architecture of Dogecoin, changing from
using the Litecoin client as its base, to Bitcoin 0.9. It's still Dogecoin,
same Scrypt PoW algorithm, same reward schedule, but there's a lot of
changes under the hood.

For the full Bitcoin 0.9 changelog, please see https://bitcointalk.org/index.php?topic=522014

Please note that this is a very early release, and a full audit of the code
is still in progress. The client has been hard-coded to only work with testnet
for now, to avoid risks of damaging real wallets.

Downgrading

First and foremost, please note that downgrading from 1.7 to 1.6 is not trivial.
1.7 now uses Berkeley DB 5.1 as its default database (in place of 4.8), and as
such may create database files which are incompatible with previous versions.

Rebranding to Dogecoin Core

Following in the footsteps of Bitcoin (Core), the Dogecoin reference client
has been rebranded as "Dogecoin Core". This helps separate its identity
from Dogecoin (the network).

dogecoin-cli

Where previously commands were sent to dogecoind by running
"dogecoind ", 1.7 adopts the model from Bitcoin Core 0.9 where there is
a separate "dogecoin-cli" executable which us used instead. This avoids the risk
of accidentally trying to start two daemons at the same time, for example.

Transaction malleability-related fixes

Fixes for risk-cases involving transaction malleability have been added; this
is particularly important for any merchants or exchanges using the built-in
wallet system.

Testnet

As mentioned at the start of this document, the alpha-client is for use on the
Dogecoin testnet only. This is an alternative Dogecoin blockchain which is
not used for real transactions, and instead is intended for testing of experimental
clients. Wallets and addresses are incompatible with the normal Dogecoin
network, in order to isolate the two.

As "test Doge" is essentially valueless, it can be acquired easily for testing,
either by mining, or from a faucet such as http://testdoge.lionservers.de/
