Do EAP 6 CPs contain previous CPs?

Issue

• Do EAP 6 CPs contain previous CPs (for example, does 6.3.2 contain 6.3.1)? Do we need to apply all CPs in order or can we just apply the latest CP alone?
• I want to use patch 03 of JBoss EAP 6.4.0. I'd like to know if I can just download and apply patch 03? Or do I have to first apply patch 01, then patch 02, then patch 03?
• Planning an upgrade from EAP6.2.4 to EAP6.4.3. I need to confirm all corrections in EAP6.2.4 are included in EAP6.4.3.
