The Terrapipe protocol was revised and promoted to 1.0. This will cause all existing client implementations to break, since the protocol has changed fundamentally. The clients have to implement the [latest spec](https://terrabasedb.github.io/docs/Protocols/terrapipe).
The only significant change in the protocol is the new metalayout format: `#a#b#c` instead of the previously proposed `a#b#c#` .
### Disk storage format
The disk storage format was changed rendering existing binary data files incompatible. However, if you have any existing data - which is important, open an issue - because we'll be able to provide a tool that can help you easily migrate your existing datasets - with a one line command - so - no worries!
