Joinmarket-clientserver 0.9.10:

https://github.com/joinmarket-org/joinmarket-clientserver/releases/tag/v0.9.10

Please report bugs using the issue tracker at github:

https://github.com/joinmarket-org/joinmarket-clientserver/issues

Upgrading

To upgrade:

Reminder: always back up and recreate your joinmarket.cfg file when doing the upgrade; this is to make sure you have the new default settings. In order to recreate it, rename the old joinmarket.cfg and run 'python3 wallet-tool.py generate' from the scripts folder.

(If you are upgrading from a version pre-0.7.0 please read the "Upgrading" section in the 0.7.0 release notes.)

(If you are upgrading from a version pre-0.9.0 please read the release notes to find out how about fidelity bonds are relevant to your use-case).

First run the install.sh script as mentioned in the README. When prompted to overwrite the directory jmvenv, accept.

Note that ./install.sh -? will show the options for installation. See the section on Installation below for a new option for Tor.

Changes

Removal of Python 3.6 support, 3.7 or newer is required now

Python 3.6 has been end-of-life since end of 2021 and Python 3.7 is also minimum requirement for planned future packaging changes.

  • 63890ee Drop Python 3.6 support
  • 9f4da21 Document requirement of Python 3.7 or newer

Fee estimation changes and fee bumping

Command line script bumpfee.py is added which gives simple way to speed up unconfirmed transaction by replacing it with higher fee paying one if all inputs belong to Joinmarket wallet (so will not work with coinjoins) and original transaction has signalled BIP125 opt-in RBF flag. BIP125 signalling is also enabled by default, in previous versions that was only possible with sendpayment.py by adding manually command line flag.

Also transaction fee randomization (which we do for privacy reasons) code is now changed to randomize only upwards, but never below the manually specified or automatically estimated fee for block confirmation target.

  • eeb362b added bumpfee.py script for bumping fees for rbf transactions
  • 907f1b0 Signal BIP125 opt-in RBF for non-cj sends by default
  • 67ff868 Randomize transaction fees only upwards
  • d5c240b Refactor fee estimation code

Wallet RPC API improvements

Two new API endpoints are added - /getinfo, which currently allows to get version of Joinmarket running in backend, and /wallet/recover, which allows recover wallet from seed phrase using API.

  • 7f4eaa9 RPC-API: add ability to recover wallet
  • 828398f RPC-API: read gaplimit from config
  • c9f6ac8 RPC-API: add getinfo endpoint.

BIP21 bitcoin: URI changes

Multiple duplicate arguments with the same key, like amount, now is parsed in guarateed order, where last one wins. That matches behaviour of Bitcoin Core.

  • 88bd45b Parse URI params in guaranteed order, for duplicates, last one wins
