Groovy Weekly #48

Almost a year since I started the Groovy Weekly newsletter. And perhaps for the first anniversary, in a handful of weeks, we’ll have reached 2000 news items shared with you all in this column!

This week is a London-ian one, as lots of the Groovy ecosystem inhabitants are migrating to the UK to celebrate the Groovy Grails eXchange conference. I’m looking forward to seeing some of you this week there. It also means that next week, you’ll likely see many links to slides and videos of the conference.

And congrats to the Griffon team for a nice Griffon 2.1 release!
