The product version you are trying to access is no longer maintained

Previously, product documentation for versions 8.7.1, 8.7.2 and 8.7.3 was combined and displayed under a single entry: Version 8.7.x (Continuous Delivery).

That combined documentation set has now been reorganized. Each of the Non-LTS versions - 8.7.1, 8.7.2 and 8.7.3 - is now available as a separate, standalone top-level documentation collection.
