v3.0.0-rc1

Hyrax 3.0.0 is a substantial release featuring a wide variety of UI improvements, metadata updates, and bugfixes as well as significant internal improvements.

The highlights for this release include:

• Support for Rails 5.2 and Ruby 2.6 are added; we now recommend Rails 5.2 for all applications.
• Out-of-the-box metadata schemas are updated to more closely align with the recommendations of the Samvera Metadata Interest Group.
• File versions and transparent PNGs are now supported by our IIIF installation. Universal Viewer's install process is improved to use yarn.
• Valkyrie is introduced as a production dependency and a custom adapter (Wings) is introduced to handle backward-compatible use of Valkyrie within Hyrax. (see more on this below)

Wings/Valkyrie

This release marks a major milestone in the transition from ActiveFedora to Valkyrie as Hyrax's persistence middleware. The introduction of Wings has allowed us to transition some portions of the Hyrax codebase to using Valkyrie natively. Likewise it allows adopters to begin the transition to Valkyrie within their own applications in a limited fashion.

At this point, we encourage early-adopters to explore using Wings through native Valkyrie interfaces and provide feedback about its suitability in Hyrax-based applications. Existing ActiveFedora models can be cast to auto-generated Valkyrie resource classes by using resource = my_object.valkyrie_resource.

A broader usage guide for Wings and Valkyrie is provided at https://github.com/samvera/hyrax/wiki/Hyrax-Valkyrie-Usage-Guide

Currently, the internal Wings adapter is the only supported Valkyrie adapter. We expect to support other adapters, and eventually deprecate Wings in future releases.

CircleCI

In support of development efforts, we migrated our CI builds from Travis to CircleCI. This has allowed us to substantially reduce build times, increasing developer productivity. It has also allowed us to expand Hyrax's build matrix: we now run builds for Ruby 2.4, 2.5 and 2.6 in parallel, helping us ensure comprehensive support for those Ruby versions.

Migration Procedures from Hyrax 2.x to 3.0

The following steps describe the process for migrating to Hyrax 3. The steps should be run in the order presented.

Update gem

Edit Gemfile or gemspec to update the version of hyrax.

gem 'hyrax', '3.0.0.pre.beta2`

and run

bundle update hyrax

Database: Application DB changes are all covered by db:migrate

Run migrations to get database changes...

rails hyrax:install:migrations
rails db:migrate

IIIF & Universal Viewer

The Universal Viewer install is now managed by yarn. Ensure UV is installed correctly by running the provided install rake task:

rake hyrax:universal_viewer:install

The number of arguments needed by the iiif_image_url_builder lambda changed.
Applications that use the riiif gem for IIIF will need to add format to the iiif_image_url_builder lambda in config/initializers/hyrax.rb.

config.iiif_image_url_builder = lambda do |file_id, base_url, size, format|

Changes
