v2.4.3 - Double check everything

This release includes a new feature to verify that fee estimations and rates did not change in the period of time between querying them and creating a Swap, some minor bug fixes and dependency updates

Bug Fixes

• use miner fees shown in API (95631d3)

Features

• implement pair hash check (f8cdcbe)
• remove ambiguous id possibilities (a88df2c)

v2.4.2 - Vulnerable

This release updates LND to v0.11.1 because of the vulnerability that was recently disclosed on the lightning-dev mailing list.

Bug Fixes

• update to LND v0.11.1 (acff8e7)

v2.4.1 - Don't force it

Cross chain Reverse Swaps that time out and have to be refunded caused some force closed channels on mainnet. This release increases the buffer between the lightning and onchain timeout block height to prevent those channel force closures.

Features

• add 10 percent buffer to CLTV expiry for cross chain Reverse Swaps (97d7ee3)

v2.4.0 - Channel for everyone

This release is a first step to enabling Channel Creation Swaps in the Boltz frontend

Bug Fixes

• relax invoice check in auto Channel Creation mode (caa4fc2)

Features

• add chain client and LND version checks (25a0417)
• send notifications when LND stream errors (#217) (f7ba741)
• try to connect by public key before opening channel (6a32a72)

v2.3.0 - Ragnarock

In this release we are introducing quite a bit of new functionality in our API:

• Channel Creation Swaps
• Creating Submarine Swaps with just a preimage hash and setting the invoice afterwards
• Querying lockup transaction of Submarine Swaps by Swap ID
• Querying the URIs of the lightning nodes of Boltz

We have also been working on an optional Reverse Swap protocol change with Electrum. We call it prepay miner fee and it requires a second invoice for the miner fee to be paid. But as of writing this, the prepay miner fee protocol change is not enabled on the official Boltz instances.

And of course we also made lots of improvements under the hood.
