# About this Release

Dash Core 0.14.0.5 is a minor release of the Dash Core 0.14.0.x series.

This is a new minor version release, bringing various bugfixes and improvements. We consider this a stable release. We suggest every node (including masternodes and non-masternode) operator to upgrade to 0.14.0.5 as this release contains a fix for a serious DoS vector.

Notable changes
===============

Fix for a DoS vector
--------------------

This release fixes a serious DoS vector which allows to cause memory exhaustion until the point of
out-of-memory related crashes. We highly recommend upgrading all nodes. Thanks to Bitcoin ABC
developers for finding and reporting this issue to us.

Better handling of non-locked transactions in mined blocks
----------------------------------------------------------

We observed multiple cases of ChainLocks failing on mainnet. We tracked this down to a situation where
PrivateSend mixing transactions were first rejected by parts of the network (0.14.0.4 nodes) while other parts
(<=0.14.0.3) accepted the transaction into the mempool. This caused InstantSend locking to fail for these
transactions, while non-upgraded miners still included the transactions into blocks after 10 minutes.
This caused blocks to not get ChainLocked for at least 10 minutes. This release improves an already existent
fallback mechanism (retroactive InstantSend locking) to also work for transaction which are already partially
known in the network. This should cause ChainLocks to succeed in such situations.
