Dispensers + Sweeps

Description

This release includes Dispensers and Sweeps (Protocol level, single message) support (effective immediatly).

Warning:

Update should be done ASAP as the rules are already active. Bootstrap download or a full reparse is required as there's already some dispensers active in mainnet and old nodes won't pick them up (and diverge).

Upgrade Timing

ASAP

For manual installations:

cd federatednode/
fednode stop
git pull
sudo rm -f data/counterparty/counterparty.*
fednode update
fednode rebuild

BTCPay Sanity Hotfix

A sanity error on a rarely ocurring event (expiration of partially filled btcpays) stopped counterparty from working. This hotfix fixes that.

Segwit + CIP19

Description

This release includes SegWit support on testnet (effective immediatly) and on mainnet (effective from an activation block). Also includes all the changes made due to implementation of CIP19.

Warning:

Updated should be done with at least a week in advance (activation of Segwit is around Jan 7th 2019) as indexd-server takes 2-4 days to sync initially and build all the indexing data (some community members will be providing torrents for downloading the initial synced database to speed up this process).

Upgrade Timing

All nodes should update before Block 557236 on mainnet. Segwit is activated on testnet since block 1440200 so a rollback to that block is suggested after update.

For manual installations:

Download the newest counterparty-lib master and update required python library versions to satisfy these versions and these versions as appropriate.

For those running a federated node with no front-end:

fednode update counterparty counterparty-testnet

For those running a full federated node with counterwallet:

fednode update
