Upgrading

Notable changes

Catch decryption errors in libnacl

66875aed6e1596cec3eac5323eddabc45e3bafb2

In the newest versions of the package libnacl, used for e2e encryption of messages between participants (since 1.5.1), a new Exception type CryptError was introduced. This will not be caught in previous versions of Joinmarket-clientserver, leading to a crash on certain inputs. For this reason it's essential to upgrade to this fix if you are running libnacl >= 1.5.1. You can check your version (while in the virtualenv) by typing pip show libnacl on the command line.

Support for spending to a bech32 address

2916d528fef2bacec87173734dab11b8b406d9e1

Now allows script and Qt users to have the destination address in any coinjoin or normal spend be a bech32 (native segwit) address. The address validation code is also updated. Note this does not add support for spending from bech32/native segwit.

Improvements to installation script including MacOS support

A dev mode for the install script; some minor fixes; support for installation script on MacOS.

Custom sighash flag support for segwit, tainting tool

6679f92eba02b27b435ad88ed2c0a1a78889e7e1, 8c24701d107e1a0248ece1ced7b2e346bb173d4a

This will not currently have any impact on everyday usage, but to support utxo tainting tools (related to adversarial fork scenarios), support was added for usage of custom sighash flags (SIGHASH_ANYONECANPAY, SIGHASH_SINGLE, SIGHASH_NONE) in segwit BIP141/143. Additionally a small script was created to allow utxo tainting, although it's been little tested or used for now.

Implement 'summary' flag in wallet-tool

5be58469469dbd60acd15552d7d213991eb21554

This produces a neat and shortened summary of coins in the wallet in each mixdepth.

Fix listening on all interfaces for standalone joinmarketd.py

467053beb938faecf64d17ac7fba2f7ef6c0e07a

This completes the fix in the previous release, applying it to the non-standard case of running joinmarketd separately.

Fix payment amount limit on 32 bit systems

b353bae139e0d60756156cc4e0a47eda14660dda

Python on 32 bit systems had a limit on integer size < the maximum spend size in satoshis, this is fixed using the numbers module.
