 8. Removed community spend proposal
 9. Allowed setting different voting periods for different proposal types
 10. Stake automatically 50% of balance for accounts that have more than 25 $GOVGEN at genesis initialization. The resulting stake distribution will provide approximately the same voting power to all genesis validators. Accounts will automatically stake to a maximum of 5 validators if 50% of the balance is less than 500 $GOVGEN, a maximum of 10 validators if less than 10,000 $GOVGEN and a maximum of 20 validators if more, uniformly. The number of validators elected for the delegations is not a constant because it depends on the state of the distribution.

+An effort has been made to make it possible to build the exact same binary
+locally as the Github Release section. To do this, checkout to the expected
+version and then simply run `make build` (which will output the binary to the
+`build` directory) or `make install`. The resulted binary should have the same
+sha256 hash than the one from the Github Release section.
