This is a normal release, bringing bug fixes and new features.

The secp256k1 library can now be used in JoinMarket. It provides the very well tested and robust code used in Bitcoin for the underlying signing and ECC operations. It is recommended that everyone who is able to use secp256k1 with JoinMarket. In case it cannot be installed, joinmarket should continue to run exactly as before.

Many small bugfixes and features have been added with the aim of making the tumbler script more stable and more likely to complete the entire tumbler job without crashing

In order to help stop spies that sybil attack the bitcoin p2p network in an effort to learn the origin IP address of a transaction, JoinMarket now has a feature to ask a maker to broadcast the coinjoin transaction with their IP.

JoinMarket debug logs are very useful to developers, but because they contain private information users are often unwilling to share them publicly.

For this reason there is now a debug log scrubber script which replaces sensitive information with placeholders that allow debugging but do not ruin privacy.

The history of the internal wallet can now be displayed. For yield-generator users it can work out the effective annual interest rate, as though yield-generator was a savings account.
