# dcrwallet v2.1.6

This is a bug fix release addressing a mixing deanonymization attack.

The pairing version to specify compatibility with other mixing peers has been increased in this release ([decred/dcrd#3765](https://github.com/decred/dcrd/pull/3765)). Wallets running this release will not mix with older wallets, or vice versa.

All users must upgrade from prior releases.

## Bug fixes

• A mixing deanonymization attack was prevented with a mixclient protocol update ([decred/dcrd#3765](https://github.com/decred/dcrd/pull/3765)).

• A failure to blame mixing peers who wrongly initiated blame assignment was fixed ([decred/dcrd#3760](https://github.com/decred/dcrd/pull/3760)).

• Mixpool message removal on session expiry was fixed ([decred/dcrd#3683](https://github.com/decred/dcrd/pull/3683)).

• The wallet now refuses to record transactions seen from the network when signature verification of spent wallet outputs fails ([`c362bea7`](https://github.com/decred/dcrwallet/commit/c362bea7)).

• SPV peers who announce transactions containing inputs spending wallet outputs with failing signature scripts are now disconnected ([`a46848a5`](https://github.com/decred/dcrwallet/commit/a46848a5)).

• Missing merkle root checks of blocks processed in SPV mode were added ([`745996b6`](https://github.com/decred/dcrwallet/commit/745996b6)).
