Overview of jBallerina 1.2.1

The jBallerina 1.2.1 patch release improves upon the 1.2.0 release by introducing the features listed below and addressing a number of bugs and improvements.

You can use the update tool to update to jBallerina 1.2.1 as follows.

For existing users:

If you are already using jBallerina version 1.2.0, you can directly update your distribution to jBallerina 1.2.1 by executing the following command:

$ ballerina dist update

However, you need to use the following commands instead of the above if you have installed:

  • jBallerina 1.2.0 but switched to a previous version: $ ballerina dist pull jballerina-1.2.1
  • a jBallerina version below 1.1.0: install via the installers

For new users:

If you have not installed jBallerina, then download the installers to install.
