Issues which were resolved in the Pega 8.2.4 Patch Release can be found here.
Please note that patch releases are cumulative. Pega 8.2.4 includes all fixes made in previous 8.2.x patch releases. Pega 8.2.4 is the highest quality 8.2.x version available!
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.
Hi sorry I didn't understand your original question. Yes all fixes made in 8.2.x will be available in 8.3.x & 8.4. There is no requirement to take the latest patch prior to upgrading to a new minor version.
