This is a new major version release, including new features, various bugfixes and performance improvements, as well as updated translations. This update includes full node, wallet and mining support for MWEB. It is recommended for all users to upgrade to this\u00a0version.<\/p>\n<h4>How to\u00a0Upgrade<\/h4>\n<p>Firstly, thank you for running Litecoin Core and helping secure the\u00a0network!<\/p>\n<p>As you\u2019re running an older version of Litecoin Core, shut it down. Wait until it\u2019s completely shut down\u200a\u2014\u200awhich might take a few minutes for older versions\u200a\u2014\u200athen follow these simple steps: For Windows: simply run the installer For Mac: copy over to \/Applications\/Litecoin-Qt For Linux: copy cover litecoind\/litecoin-qt.<\/p>\n<p>NB: upgrading directly from an \u2018end of life\u2019 version of Litecoin Core is possible, but it might take a while if the data directory needs to be migrated. Old wallet versions of Litecoin Core are generally supported.<\/p>\n<h4>Compatiblity<\/h4>\n<p>Litecoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, Windows 7 and newer. It\u2019s not recommended to use Litecoin Core on unsupported systems.<\/p>\n<p>Litecoin Core should also work on most other Unix-like systems, but is not as frequently tested on\u00a0them.<\/p>\n<p>MWEB fields added to BlockIndex, and block serialization format has changed. Downgrading to older versions is unsafe. If upgrading to 0.21.2 <em>after<\/em> MWEB has activated, you must resync to download MWEB\u00a0blocks.<\/p>\n<h4>Notable Changes<\/h4>\n<h4>Consensus Changes<\/h4>\n<ul>\n<li>This release implements the proposed MWEB consensus rules (<a href=\"https:\/\/github.com\/litecoin-project\/lips\/blob\/master\/lip-0002.mediawiki\">LIP002<\/a>, <a href=\"https:\/\/github.com\/litecoin-project\/lips\/blob\/master\/lip-0003.mediawiki\">LIP003<\/a>, and\u00a0<a href=\"https:\/\/github.com\/litecoin-project\/lips\/blob\/master\/lip-0004.mediawiki\">LIP004<\/a>)<\/li>\n<\/ul>\n<h4>P2P and network\u00a0changes<\/h4>\n<ul>\n<li>A new service flag, NODE_MWEB (1 &lt;&lt; 24), was added to signal to peers that the node supports MWEB. When connected peers both advertise this capability, they are expected to provide all MWEB data when sharing transactions, blocks, and compact blocks with each\u00a0other.<\/li>\n<li>Nodes now announce compact block version 3 support, informing peers that they can provide MWEB data in compact\u00a0blocks.<\/li>\n<\/ul>\n<h4>Updated RPCs<\/h4>\n<ul>\n<li>getblockheader now returns an additional mweb_header field containing all of the MWEB header data, and an mweb_amount field containing the total number of coins pegged-in to the MWEB after applying the\u00a0block.<\/li>\n<li>getblock now returns an additional mweb field containing MWEB header info, and all of the inputs, outputs, and kernels in the MWEB\u00a0block.<\/li>\n<li>Added mwebweight, descendantmwebweight, ancestormwebweight, and mweb fields to getrawmempool, getmempoolancestors, getmempooldescendants, and getmempoolentry.<\/li>\n<li>Added new fields to describe MWEB transaction inputs, outputs, and kernels for getrawtransaction.<\/li>\n<\/ul>\n<p>Changes to Wallet or GUI related RPCs can be found in the GUI or Wallet section\u00a0below.<\/p>\n<h4>New settings<\/h4>\n<ul>\n<li>Added \u201cfMWEBFeatures\u201d option for enabling the new \u201cAdvanced MWEB Features\u201d control.<\/li>\n<\/ul>\n<h4>Wallet Database<\/h4>\n<ul>\n<li>Added \u201cmweb_coin\u201d type which stores MWEB coins and their derived\u00a0keys.<\/li>\n<li>Added CHDChain version 4 which includes an MWEB key index counter and the stealth address scan\u00a0key.<\/li>\n<li>Added CKeyMetadata version 14 which includes the MWEB key\u00a0index.<\/li>\n<li>Added FEATURE_MWEB = 210000 minimum database\u00a0version.<\/li>\n<\/ul>\n<h4>Wallet RPC\u00a0changes<\/h4>\n<ul>\n<li>Added \u2018listwallettransactions\u2019 which matches the transaction list display\u00a0values.<\/li>\n<\/ul>\n<h4>GUI changes<\/h4>\n<ul>\n<li>Added an \u201cAdvanced MWEB Features\u201d control for testing. It\u2019s only available when the \u201c-debug\u201d argument is supplied, and the option is turned on in the settings\u00a0dialog.<\/li>\n<\/ul>\n<h4>Download Binaries<\/h4>\n<p>To download, please visit the download page <a href=\"https:\/\/litecoin.org\/\">here<\/a>.
