+Litecoin Core version 0.21.2 is now available from:
+
+ <https://download.litecoin.org/litecoin-0.21.2/>.
+
+This is the largest update ever, providing full node, wallet, and mining support for MWEB.
+
+Please report bugs using the issue tracker at GitHub:
+
+  <https://github.com/litecoin-project/litecoin/issues>

+
+
+How to upgrade: 
+==============
+
+Firstly, thank you for running Litecoin Core and helping secure the network!
+
+As you’re running an older version of Litecoin Core, shut it down. Wait until it’s completely shut down  - which might take a few minutes for older versions - then 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`.
+
+NB: upgrading directly from an ‘end of life’ 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.
+ 
+
+Compatibility:
+==============
+
+Litecoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+,  Windows 7 and newer. It’s not recommended to use Litecoin Core on unsupported systems.
+
+Litecoin Core should also work on most other Unix-like systems, but is not as frequently tested on them.
+
+MWEB fields added to BlockIndex, and block serialization format has changed. Downgrading to older versions is unsafe.
+
+If upgrading to 0.21.2 *after* MWEB has activated, you must resync to download MWEB blocks.
+
+Notable changes
+===============
+
+Consensus changes
+-----------------
+
+- This release implements the proposed MWEB consensus rules
+  ([LIP002](https://github.com/litecoin-project/lips/blob/master/lip-0002.mediawiki),
+  [LIP003](https://github.com/litecoin-project/lips/blob/master/lip-0003.mediawiki), and
+  [LIP004](https://github.com/litecoin-project/lips/blob/master/lip-0004.mediawiki))
+
+P2P and network changes
+-----------------------
+
+- A new service flag, NODE_MWEB (1 << 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 other.
+
+- Nodes now announce compact block version 3 support, informing peers that they can provide MWEB data
+  in compact blocks.
+
+
+Updated RPCs
+------------
+
+- `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 block.
+
+- `getblock` now returns an additional `mweb` field containing MWEB header info,
+  and all of the inputs, outputs, and kernels in the MWEB block.
+
+- Added `mwebweight`, `descendantmwebweight`, `ancestormwebweight`, and `mweb`
+  fields to `getrawmempool`, `getmempoolancestors`, `getmempooldescendants`,
+  and `getmempoolentry`.
+
+- Added new fields to describe MWEB transaction inputs, outputs, and kernels
+  for `getrawtransaction`.
+
+Changes to Wallet or GUI related RPCs can be found in the GUI or Wallet section below.
+
+New settings
+------------
+
+- Added "fMWEBFeatures" option for enabling the new "Advanced MWEB Features"
+  control.
+
+Wallet Database
+---------------
+
+- Added "mweb_coin" type which stores MWEB coins and their derived keys.
+
+- Added CHDChain version 4 which includes an MWEB key index counter and
+  the stealth address scan key.
+
+- Added CKeyMetadata version 14 which includes the MWEB key index.
+
+- Added FEATURE_MWEB = 210000 minimum database version.
+
+Wallet RPC changes
+------------------
+
+- Added 'listwallettransactions' which matches the transaction list display values.
+
+GUI changes
+-----------
+
+- Added an "Advanced MWEB Features" control for testing. It’s only available
+  when the "-debug" argument is supplied, and the option is turned on in the
+  settings dialog.
