1. Refactors to pool4 add mark-dependent sourcing and port ranges (which in turn removes the need for a second IPv4 address), and fixes the excessive memory usage.
2. The EAMT now implements Hairpinning and overlapping entries, which are newer updates to the EAM draft.
3. Minimal namespace features, which allow Host-Based Edge Translation (now called Node-Based Translation) and (subjectively) better filtering.
4. The userspace application now prints the friendlier error messages that used to be dumped in the kernel log only.
5. Removed reliance on dead code deletion, which used to prevent compilation on some systems.
6. Two bugfixes.
7. Spanish documentation.
8. `--csv` can now be used on all configuration targets.
