Electrum 4.5.0 released

[nc50lc]

* Plugins:
   - new: swapserver plugin (#8489)

Does anyone understand what this plugin does? I briefly checked relevant pull link at 8489, but i only can figure out it's related with LN.

Yes, it's related to Lightning.
It's a plugin that enables the user to set a custom "swapserver" by adding the lines below or by using "setconfig" commands via daemon:

•    "use_swapserver": true,
•    "swapserver_address": "swapserver_address:swapserver_port",

By default, Electrum uses Boltz for submarine swaps.
I can't find any official documentation on how to set up the swapserver though.

-edit-
"swapserver_address" changed to 'port' after this commit (in v4.5.1): https://github.com/spesmilo/electrum/commit/f30d81a98fe8d7cde6daae4e15eba7b4852e43d9

By default, Electrum uses Boltz for submarine swaps.

It's a plugin to run your own swap server, it is an alternative implementation to Boltz.

- You can point the client to any remote swap server by setting the "swapserver_url" config key (unrelated to plugin),
- and it is possible to run a swap server yourself locally using this new plugin (which itself is a server implementation in python).

We wrote the plugin for our own use, to replace Boltz, as they changed their license from AGPL to a non-free license around 2023-04.
Since around 2023-08 we are no longer using Boltz. That is, the official swap server is now an electrum daemon with this plugin enabled.

Okay, so this is the reason why there's always a "The swap server errored or is unreachable" error whenever I try using submarine swap.
It would've been great if this info is mentioned in the release notes, though.
