We are pleased to release Litecoin Core 0.17.1 release candidate. This is a new major version release, including new features, various bug fixes, performance improvements and updated translations.
It is recommended for power users to upgrade to this version. After sufficient testing, Litecoin Core 0.17.1 final will be released and is recommended for all users to upgrade.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).
If your node has a txindex, the txindex db will be migrated the first time you run 0.17.1 or newer, which may take up to a few hours. Your node will not be functional until this migration completes.
The first time you run version 0.15.0 or newer, your chainstate database will be converted to a new format. This 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. Upgrading directly from 0.7.x and earlier without redownloading the blockchain is not supported. However, as usual, old wallet versions are still supported.Downgrading warning
The chainstate database for this release is not compatible with previous releases, so if you run 0.15 and then decide to switch back to any older version, you will need to run the old release with the -reindex-chainstate option to rebuild the chainstate data structures in the old format.
If your node has pruning enabled, this will entail re-downloading and processing the entire blockchain.Compatibility
