Release Note

We are happy to announce the release of 0.14.0.5. This release includes binaries, which can be downloaded above.
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 which in its turn 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.
