Notably:

- Enterprise is delivered in an OVF, which means it's a fully contained VM. This simplifies deployments astronomically from the previous FI architecture.

- We've spent a lot of time on the runtime and packaging of Enterprise in relation to how it runs the code. It's now much faster.

- We've changed how we merge the two codebases (.com and FI/Enterprise). Effectively, they are the same now. This means new features that come to .com will come to Enterprise quickly/immediately. Previously we had to do hard, manual merges which meant new features got to FI very late (3, 6, 8 months later).
