v1.2.4 Release Notes
Released April 8, 2019.
### Docker ```sh docker pull yugabytedb/yugabyte:188.8.131.52-b5 ```
File Format Change
NoteThis version includes a backward incompatible file format change for YSQL. This means that if you have an existing cluster with YSQL schema, then you will not be able to connect to the YSQL database after upgrading to this version.
There are two ways to address the above note.
- If you don't care about preserving your existing data, then you can delete your older cluster, upgrade to v1.2.4 and create a new cluster.
- If you want to continue using your existing data, then please save your older data (in the form of SQL statements), delete the older cluster, upgrade to v1.2.4, create a new cluster and then load the previously saved data.
