The Tokio community is most readily found on its gitter channel, where you’re welcome to ask questions, report problems, or pitch ideas.
Github is used for tracking issues.
We also have an issue tracker on the main Tokio repository
If you’re a Tokio user, you’re highly encouraged to keep an eye on these issues and jump in on the discussions, to help us understand how design tradeoffs might affect you.
These repositories also contain milestones for upcoming major releases, which are currently used to track breaking changes that might be considered for the next major release.
