+Dash Core version 18.0.2
+========================
+
+Release is now available from:
+
+  <https://www.dash.org/downloads/#wallets>
+
+This is a new hotfix release.
+
+Please report bugs using the issue tracker at github:
+
+  <https://github.com/dashpay/dash/issues>
+
+
+Upgrading and downgrading
+=========================
+
+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/Dash-Qt (on Mac) or
+dashd/dash-qt (on Linux). If you upgrade after DIP0003 activation and you were
+using version < 0.13 you will have to reindex (start with -reindex-chainstate
+or -reindex) to make sure your wallet has all the new data synced. Upgrading
+from version 0.13 should not require any additional actions.
+
+When upgrading from a version prior to 18.0.1, the
+first startup of Dash Core will run a migration process which can take anywhere
+from a few minutes to thirty minutes to finish. After the migration, a
+downgrade to an older version is only possible with a reindex
+(or reindex-chainstate).
+
+Downgrade warning
+-----------------
+
+### Downgrade to a version < v18.0.1
+
+Downgrading to a version older than v18.0.1 is not supported due to changes in
+the indexes database folder. If you need to use an older version, you must
+either reindex or re-sync the whole chain.
+
+### Downgrade of masternodes to < v18.0.1
+
+Starting with the 0.16 release, masternodes verify the protocol version of other
+masternodes. This results in PoSe punishment/banning for outdated masternodes,
+so downgrading even prior to the activation of the introduced hard-fork changes
+is not recommended.
+
+Notable changes
+===============
+
+This release resolves some excessive memory usage via the "evo" database (evodb).
