Bespin - Evans

This is an RC (release candidate) release of the next major version of the Python client for the Raiden Network.
Don't run it on mainnet!

A lot of work on the transport layer as well as the services went into this release. To improve performance and reliability on the transport layer it was necessary to implement some backwards incompatible changes.

Backwards compatibility status:

• v2.x clients WILL NOT be compatible with and not be able to perform transfers with any earlier versions
• The EXISTING CLIENT DATABASE WILL ALSO NOT BE COMPATIBLE.
  This means channels opened with older versions need to be closed, settled and re-opened.
  This shouldn't cause any particular harm on test-networks. For mainnet we will provide support for users.

Change log:

• #7064 Fix building of binary bundles which was broken for a while.
• #6986 Increment DB version - this will make this release incompatible with previous releases. Please refer to the known issues section in the docs for details.
• #6851 Raiden does not use Matrix rooms anymore. This greatly reduces the load on the matrix servers and increases the reliability of the transport layer.
• #6898 Add support for Geth 1.10.
• #6947 Add support for Python 3.9.
• #6821 API endpoint for UserDeposit contract deposits/withdraws
• #6763 Ensure that pending messages are sent before Raiden is stopped
• #6563 Faster syncing with the blockchain.
• Update WebUI to version 1.2.1. Introduces a new "Quick Connect", that is simpler and more transparent than the old "join token network" feature, and adds a dialog for interacting with the UserDeposit contract (UDC).
• #4730 Remove "join token network" feature from API. Explicitly create and fund channels, instead.
• #6582 Add /settings endpoint with information about the used pathfinding service.
• #6657 Support for recent geth versions.
• #6541 Remove internal routing.
