While working on Universal Render Pipeline for 2019.3 we developed an integrated post-processing stack that is better coupled with the pipeline. This allowed us to deliver several performance improvements in the pipeline. The new stack also supports new effects like Camera Motion Blur and the Volume Framework. Earlier this year we decided to drop support for PPv2 in URP in favor of this new integrated post-processing stack. However, the new stack is currently missing a very important feature for users: custom post-processing. Over the past months we have received several pieces feedback about this decision. Lack of custom post-processing is perceived as a regression from PPv2. Major concerns were also raised about the timeline of the PPv2 deprecation in URP and the lack of support for all custom post-processing effect written for that stack. Based on this feedback, we decided to add support to PPv2 in URP as a fallback mode in 2019.4 LTS. This way developers will have a choice to still keep using PPv2 for the next 2 years in LTS and we will remove support for PPv2 in UPR in 2020.1 instead. If you have PPv2 package installed, there will be an option to select PPv2 stack from the pipeline asset. It works the same way as it used to work in LWRP and with the same limitations (no support for Ambient Occlusion, Temporal Anti-aliasing and Motion Blur).
