If you are doing UI work in hawkular(rhq-metrics right now), the version of typescript has been bumped to version 1.4.1. This is reflected in the build so nothing is needed to be done. However, if you are doing UI dev work then you should update the version of typescript so that your IDE will pick up the new version. As a first step, I have changed the version but not added any typescript 1.4.1 syntax changes to minimize change as a first step. Syntax additions will find their way into the codebase soon though. To check which version you are using use ‘tsc —version’. If you are using npm to load typescript you can use the command ‘npm update typescript -g’ to update to the new version. — Mike
