O'Reilly sent an email about the update yesterday (a bit late but still), I posted an update on my blog: http://merbist.com and on twitter via @merbist which was retweeted by @macruby not sure what more I could do ;) Suggestions welcome tho.
I'd like to make sure people know when I push an update. I'm also thinking about offering a diff of the changes so one can easily see the modifications. - Matt On Thu, Jan 20, 2011 at 9:48 AM, Martin Hawkins <martin.hawk...@gmail.com>wrote: > Thanks, Matt; so I see.
