It's moving along...a bit slower now that we're into the sugaring season. Not all chapters are being updated, but the majority are. Given the massive changes in the industry, there are a lot of changes to some of the chapters. Revised chapters were submitted by authors, then externally reviewed. Dr. Abby and I then reviewed and edited them (some more, some less). They were then sent out to Drs. Randy Heiligmann and Mel Koelling for comments. They've finished most of them and I have them back for incorporating their comments. I expect we'll have them out to a copy editor and layout over the summer and fall. Hoping to have the entire thing completed by this time next year.
