This version features integration with our new registration provider, https://JMP.Chat, for which we’re having a beta test on our test instance (that is, it is not installed on the production server yet, but will be soon). One more time I want to thank the guys at JMP.Chat, especially @ossguy which was very kind and helpful in the whole integration process.
F-Droid version will follow in a day or two as usual. And as always, you’re encouraged to open issues on GitHub or discuss them here in the support category.
Next version (bearing hotfix releases) will have location sharing by @a.cappelli87. And I believe this deserves incrementing the minor version, so expect a 4.1.0…
