We have received reply from Electrum author. Plugin won't be included in wallet by default. Author believes it would create a law risk to add mixer into wallet. Our hook was merged so our plugin will work with new version, but it will need to be installed separately.
We have published an article at r/Bitcoin about how to use ChipMixer to avoid upcoming "declare cryptocurrencies" US law:
https://www.reddit.com/r/Bitcoin/comments/6jzc41/easy_way_to_avoid_upcoming_us_declare_btc_law/It would be still good news if it won't be added in plugin since it can be still installed in new version but separately it would be still a great news..
That we can use more easily to mix with electrum..
Hope that they can release it fast i'll be willing to test it since i really looking for a good wallet that has a mixer for a long time..
