Litecoin Core version 0.16.2 is now available from: This is a new minor version release, with various bugfixes as well as updated translations. Please report bugs using the issue tracker at GitHub: To receive security and update notifications, please subscribe to: 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. Downgrading warning ------------------- 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. Compatibility ============== 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. Notable changes =============== Miner block size removed ------------------------ The `-blockmaxsize` option for miners to limit their blocks' sizes was deprecated in version 0.15.1, and has now been removed. Miners should use the `-blockmaxweight` option if they want to limit the weight of their blocks' weights. 0.16.2 change log ------------------ ### Policy - #11423 `d353dd1` [Policy] Several transaction standardness rules (jl2012) ### Mining - #12756 `e802c22` [config] Remove blockmaxsize option (jnewbery) ### Block and transaction handling - #13199 `c71e535` Bugfix: ensure consistency of m_failed_blocks after reconsiderblock (sdaftuar) - #13023 `bb79aaf` Fix some concurrency issues in ActivateBestChain() (skeees) ### P2P protocol and network code - #12626 `f60e84d` Limit the number of IPs addrman learns from each DNS seeder (EthanHeilman) ### Wallet - #13265 `5d8de76` Exit SyncMetaData if there are no transactions to sync (laanwj) - #13030 `5ff571e` Fix zapwallettxes/multiwallet interaction.
