We are pleased to release Litecoin Core 0.16.3 release. This is a new minor version release, including a very important security update. It is recommended for all users to upgrade to this version as soon as possible.
How to Upgrade
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Litecoin-Qt (on Mac) or litecoind/litecoin-qt (on Linux).
The first time you run version 0.15.0 or newer, your chainstate database will be converted to a new format, which will take anywhere from a few minutes to half an hour, depending on the speed of your machine.
Note that the block database format also changed in version 0.8.0 and there is no automatic upgrade code from before version 0.8 to version 0.15.0 or higher. Upgrading directly from 0.7.x and earlier without re-downloading the blockchain is not supported. However, as usual, old wallet versions are still supported.
Wallets created in 0.16 and later are not compatible with versions prior to 0.16 and will not work if you try to use newly created wallets in older versions. Existing wallets that were created with older versions are not affected by this.
Litecoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.
Litecoin Core should also work on most other Unix-like systems but is not frequently tested on them.
A denial-of-service vulnerability (CVE-2018–17144) exploitable by miners has been discovered in Litecoin Core versions 0.14.0 up to 0.16.2. It is recommended to upgrade any of the vulnerable versions to 0.16.3 as soon as possible.
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 this release, the binaries have been signed with key identifier FE3348877809386C (thrasher’s key).
Despite this version being heavily tested, this version may still contain bugs. Always backup your wallet.dat file before upgrading. If you encounter any issues, please let us know by posting to the bug reporting section below.
