The answer is simple: it represents the perfect balance between content and stability. Earlier versions (like v0.07) were promising but had less content and more bugs. Later versions (like v0.09) are intriguing but may not yet have the same level of community testing and support as v0.08. The v0.08 build is the community-proven, feature-rich, "ongoing" standard that offers the most complete and polished Apocalust experience currently available.
