New ActiveFedora and Hydra-Head releases

Wouldn’t you know it?  As soon as your scribe goes on vacation, a flurry of gem updates!  Apologies that this notification is a little after the fact.

These releases will make up the bulk of the upcoming release of the hydra gem (6.1).  They are the last planned feature releases of the version 6 line, so they contain a number of deprecations which will assist you in upgrading to version 7.

These releases have been brought to you by Duke (David Chandek-Stark), Notre Dame (Jeremy Friesen), Northwestern University (Michael B. Klein), Penn State (Carolyn Cole), The Boston Public Library (Steven Anderson), Indiana University (Chris Colvard), and Data Curation Experts (Justin Coyne).

ActiveFedora 6.7.0

Even though we said ActiveFedora 6.6.0 would be the last minor release of the 6.x line, we uncovered an issue with the ‘delegate’ and ‘delegate_to’ methods.  Thus, we have changed these methods to both be covered by a new method named “has_attributes”.  You shouldn’t need to make any changes to upgrade to ActiveFedora 6.7.0, but you may see more deprecation warnings that you will want to fix before upgrading to ActiveFedora 7.

Additionally there is a patch for an issue when changes were being tracked against methods that were not metadata attributes.

We’ve also added a patch to prevent the rake tasks from loading twice.
