Issues which were resolved in the Pega 8.1.9 Patch Release can be found here.
Please note that patch releases are cumulative. Pega 8.1.9 includes all fixes made in previous 8.1.x patch releases. Pega 8.1.9 is the highest quality 8.1.x version available!
Pega releases patch versions for minor releases of software up to 18 months after its initial release (GA). When the final patch for a minor version is released, that minor version enters “extended support.” We strongly recommend that clients upgrade to the latest minor version release prior to their minor release reaching extended support.
Back in 2018, with the release of Pega 8.1, we announced our shift from hotfixes to Patch Releases. The patch release program approach allows us to bundle, test, & release bug and security fixes over a given period into a cumulative patch that will be available to all customers. This new process provides value to your business through improved overall quality and better dependency management. Look for a new cumulative patch release to be made available every month.
