Litecoin Core v0.10.2.2 FINAL Release Candidate
« on: June 19, 2015, 06:50:03 AM »
IMPORTANT
v0.10.2.2 is now the official release version of Litecoin Core and a new thread has been created for it here. 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 here.


What's New in version v0.10?
This is a major release of Litecoin Core, featuring the technical equivalent of Bitcoin v0.10.2 but with Litecoin specific patches. On a general level, most of what is new is is hidden where 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. For some examples on what has changed, please see below:

    BeforeAfterExplanation
    rpcallowip=10.0.0.1       rpcallowip=10.0.0.1Allow RPC access from IP address 10.0.0.1
    rpcallowip=10.0.0.*       rpcallowip=10.0.0.0/24Allow RPC access from IP addresses  10.0.0.1-254 (CIDR address example)
    rpcallowip=10.0.*     rpcallowip=10.0.0.0/16Allow RPC access from IP addresses 10.0.0.1-10.0.255.254 (another CIDR address example)
    rpcallowip=*          rpcallowip=::/0Allow RPC access from any IP address (not recommended!)
    rpcallowip=192.168.1.*  rpcallowip=192.168.1.1/255.255.255.0Allow RPC access from IP addresses 192.168.1.1-192.168.1.254 (netmask example)

    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 Litecoin v0.10 because we backported it to Litecoin v0.8 (like Coin Control).

What’s New in version v0.10.2.2?
Litecoin 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 Litecoin 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
To enhance the security of Litecoin Core releases, we have changed the GPG signing procedure and opted for one of the Litecoin development team members to individually sign the release binaries.

Prior to this, we used a team signing key. The problem with this is that if the key were to be compromised, we would not be able to identify the member of who it was obtained from. Switching to this new procedure allows us to pinpoint the leak, revoke the individual key and leads to further decentralization of the build process.

As with any release, please use GPG to verify the integrity of the release binaries. This ensures that the binary you have downloaded has not been tampered with. Linux, MacOS and Win32 cygwin command line GPG instructions are available here. Please also note that we GPG sign the binaries as a convenience to you, the ultimate way to verify the integrity of the builds is to build them yourself using Gitian. Instructions on how to perform these builds, can be found here.

For the v0.10.2.2 release, the binaries have been signed with key identifier FE3348877809386C.

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

Everyone please welcome Adrian Gallagher (thrasher) who is now our Release Manager.  He has been helping me for the past 2 years, and in recent months I have been training him so that he can handle all parts of the release process.  Every commit that went into this has been reviewed by me and/or pooler and tested by thrasher.

When it is supposed to be a Final version, without RC?

Thank you all for the welcoming :)

This is likely to be the version that becomes the actual release, dependant on if any issues are encountered.

How to compile in Linux? Every guide I've found so far says:

Code: [Select]
make -f makefile.unix USE_UPNP=-

Which results in:

Code: [Select]
[email protected]:~/litecoin/src$ make –f makefile.unix USE_UPNP=-
make: *** No rule to make target `–f'.  Stop.

Thanks!

Litecoin v0.10.2.2 and onwards uses autoconf, you can find the build instructions here:

RC's are meant to be exactly their name, a Release Candidate.  This specific build could be what we release on litecoin.org.  This is why everyone must be testing it now.

Problems were found in the previous few RC's, requiring fixes in upstream Bitcoin.  I have a strong degree of confidence in this build.
