UnstoppableSwap GUI 2.0.0 released with 'breaking protocol change'

binarybaron1 has released UnstoppableSwap GUI2 version 2.0.03 with a breaking protocol change and various improvements:

Please upgrade as soon as possible. Takers/GUIs running >= 2.0.0 will not be able to initiate new swaps with makers/asbs running < 2.0.0. The upgrade contains a bunch of improvements related to consistent reliable Electrum connections and a breaking protocol change.

Changes overview

* [Breaking] Takers/GUIs running >= 2.0.0 will not be able to 
initiate new swaps with makers/asbs running < 2.0.0
* tx_refund_early will only be published if the maker has not locked their Monero yet
* ASB: Return a zero quote when quoting fails
* GUI: Build Flatpak bundle in release workflow
* GUI + CLI + ASB: We now do load balancing over multiple Electrum servers
* docs: Instructions for verifying GUI (Tauri) signature files [..]

The complete changelog and binarybaron’s GPG signing key are available on Github4.

To verify the signatures and learn more about the BTC-XMR cross-chain atomic swaps project, consult the docs5 and the associated CCS proposal6.

Note: it is recommended to complete all pending swaps before upgrading. Join #unstoppableswap-core7 on Matrix to follow project development.
