Great stuff! I updated the client (no fresh install needed, just ran the .msi), got the snapshot through regular Download Blocks command and everything seems to be in sync for the past 3 hours.
For faster adoption of the new version, I think gridcoin.us site should be updated with a visible and clear announcement (the download wallet link is corect, but the blog section's last entry is for 3.7.4 version)
This will be updated soon (in the next day or two)
