 Notable changes
 ===============
 
-Fixed governance votes pruning for invalid masternodes 
-------------------------------------------------------
-A community member reported a possible attack that involves DoSing masternodes to force the network
-to prune all governance votes from this masternodes. This could be used to manipulate vote outcomes.
+Performance improvements
+------------------------
+Slow startup times were observed in older versions. This was due to sub-optimal handling of old
+deterministic masternode lists which caused the loading of too many lists into memory. This should be
+fixed now.
 
-This vulnerability is currently not possible to execute as LLMQ DKGs and PoSe have not activated yet on
-mainnet. This version includes a fix that requires to have at least 51% masternodes to upgrade to
-0.14.0.1, after which superblock trigger voting will automatically fix the discrepancies between
-old and new nodes. This also means that we will postpone activation of LLMQ DKGs and thus PoSe until
-at least 51% of masternodes have upgraded to 0.14.0.1.
+Fixed excessive memory use
+--------------------------
+Multiple issues were found which caused excessive use of memory in some situations, especially when
+a full reindex was performed, causing the node to crash even when enough RAM was available. This should
+be fixed now.
 
-Fixed a rare memory/db leak in LLMQ based InstantSend
------------------------------------------------------
-We fixed a rare memory/db leak in LLMQ based InstantSend leak which would only occur when reorganizations
-would happen.
+Fixed out-of-sync masternode list UI
+------------------------------------
+The masternode tab, which shows the masternode list, was not always up-to-date as it missed some internal
+updates. This should be fixed now.
