My absolute favorite messaging app  but... Even though the app/service is excellent and fixes come quick (which is great)  this technically isn't an open source application since these latest updates aren't being hosted on GitHub anymore. Fix that ASAP  it's one of your bigger selling points compared to others. While you're at it  re-enable the damn issue tracker. If you're going to claim to be an open-source project  don't make it miserable for the open-source community help a bit.
