Fastcoin Core v0.10.2.2 Win-x64, Win-x86, OSX-x86, OSX-x64, Linux-x86, Linux-x64 IMPORTANTv0.10.2.2 is now the official release version of Fastcoin Core. On top of the new features,
this update contains very important security fixes and all users MUST upgrade to this version as soon as possible as details on several vulnerabilities will be made public on July 7th (Official Bitcoin warning). Pool operators, P2Pool and solo miners especially, as once BIP 66 is enforced, version 2 blocks will be rejected from the network entirely. P2Pool miners must upgrade to the latest version which can be obtained from
forrestv's repo.What's New in version v0.10?This is a major release of Fastcoin Core, featuring the technical equivalent of Bitcoin v0.10.2 but with Fastcoin specific patches. The block synchronization and various internals are considerably faster and more efficient, and it has several major privacy improvements. The most significant changes include:
- Watch-only wallet support. This allows the wallet to track transactions to and form wallets for which you know the address of but do not have the private key to.
- Faster blockchain synchronization due to headers-first synchronization and support for downloading blocks in parallel. Downloading the blockchain is now much quicker and can be completed within a few hours instead of taking days for some users.
- A REST interface which allows unauthenticated access to public node data when the -rest flag is specified.
- RPC Server “Warm-Up” Mode which starts earlier than previous versions. This helps users or services relying on it know that the server has already started and will be available soon.
- Improved signing security. This is due to using the libsecp256k1 library for signing instead of OpenSSL. libsecp256k1 is a cryptographic library optimized for elliptic curve uses which Litecoin relies on and was created by Bitcoin Core developer Pieter Wuille. Featuring better security, via hardening against timing leaks and derandomization, this library is believed to be better tested and more thoroughly reviewed than the implementation in OpenSSL.
- New utility applications including litecoin-tx for transaction related functionality and litecoin-cli for RPC command line functionality as litecoind no longer accepts them.
- Strict DER encoding for signatures (BIP 66). This introduces block version 3 and a new consensus rule which prevents non-standard transactions from being included in blocks. This also removes the dependency on OpenSSL’s signature parsing. Eventually, libsecp256k1 will be used for all consensus related tasks, depreciating the need for OpenSSL entirely.
- RPC Access Changes. RPC access now supports binary network addresses. This means that you can specify a single IP address, a CIDR network address or a netmask for accessing the RPC service.
- Please note, wildcard string matching no longer works and will display an error in the debug.log file when you attempt to use use a wildcard string in the rpcallowip= variable, either as a config setting or launch parameter.
Example: Allow RPC access from IP addresses 192.168.1.1-192.168.1.254
rpcallowip=192.168.1.1/255.255.255.0
Note: IPv6 addresses can also be used.
The major user-visible features that were new in Bitcoin v0.9 and v0.10 are not actually new for Fastcoin v0.10 because we backported it to Fastcoin v0.8 (like Coin Control).

Fastcoin v0.10.2.2 is a minor release from the previous release candidate, featuring improvements and bug fixes. The changes can be seen below:
- Added option -alerts’ to opt out of the network alert system. Please note that disabling network alerts should only be used by power users as this system is used for network emergencies and important security releases. The default behavior is that network alerts are enabled.
- Detect and reject LibreSSL. This prevents a non-approved SSL library being used for compiling Fastcoin Core, preventing potential consensus compatibility issues.
- Improved getbalance RPC functionality to allow the user to display zero confirmation transactions (this works with watch-only addresses as well).
- PID file bug fix for non-Windows based systems.
- Bug fix for signing and verifying messages.
- New GPG Signing Process

While this branch has been extensively tested to be compatible with the existing Fastcoin 0.8 network there is the possibility that we missed something. BACKUP YOUR FASTCOIN DATADIR and wallet.dat because after you run v0.10 the old v0.8 version is no longer compatible with your on-disk data.
