We are still following the roadmap. vaults phase 2/3/4 → Fleming → Maxwell → Beta .We are targeting phase 2 right now. Big difference is we are using 100% production code in these phases where possible. Rather than small projects with mock code to mock remaining work we are putting all code in place and iterate the full vault codebase. Doing that decreases periods between releases as we are not coding side streets to then remove them.
In essence,
Phase 2a : we will have a small section of only elders (a few nodes) and test that.
phase 2b : We will then add more nodes to create a large section.
phase 3: Add farming algorithm (this may happen in parallel with above)
phase 4: Add more nodes to allow the network to split (sharding)
All that works, we have Fleming.
Add in upgrades and possibly async/await code and we have Maxwell.
all that works, we are in Beta
