• Upstream changes to happen in the `master` branch for the Che 7.44 release. (February 23)
• Downstream changes to happen in the `master` branch for the CRW 2.16 release.
• Upstream: remove from the installation guide the "Installing {prod-short} on OpenShift Container Platform 3.11" chapter and all related modules and files. Remove xrefs and links pointing to this chapter or its content.
• Upstream, then downstream: remove any remaining occurrences of the `ocp3-ver`attribute. In particular, in the supported platforms example (upstream: `modules/installation-guide/examples/ref_che-supported-platforms-and-installation-methods.adoc`; downstream: `docs/titles/crw/release_notes/topics/crw/installation-guide/examples/ref_crw-supported-platforms-and-installation-methods.adoc`)
• Upstream and downstream: edit the ocp4-ver-min and ocp4-ver attributes, remove the ocp3-ver attribute. (upstream: in the antora.yml file; downstream: in the docs/titles/crw/meta/product-attributes.adoc file)
