+[`abra`](https://git.coopcloud.tech/coop-cloud/abra) served us well but we're porting it to [Golang](https://golang.org) over in [`go-abra`](https://git.coopcloud.tech/coop-cloud/go-abra). To learn more about the reasons for that, see [this blog post](https://coopcloud.tech/blog/this-month-in-coop-cloud-july/). This means this repository and tool are officially deprecated as of August 1rst 2021. We will still provide bug security fixes but no new features will be developed in `abra`. Feel free to go on using it and reporting issues against this issue tracker. Thanks for all the good times Bash.
