The latest PMP version is 10.4 (10402). If you are using an earlier version, you need to apply upgrade pack.
The details of all minor releases are covered in this page. You can apply these PPMs if any of your expected New Features/Enhancements/Bug Fixes are included in them. However, we recommend a periodic upgrade, preferably during every major release, for you to stay updated and make use of all the latest features. Please note, all the PPMs here will be moved to the main upgrade page
