Gems and documentation
The tables below detail the latest and recent feature releases for Hydra's gems, all of which are available from rubygems.org
Each documentation link will take you to the latest version of the documentation for a gem. If you think a piece of documentation refers to an earlier release, please let us know at hydra-tech@googlegroups.com as soon as possible and we will arrange to correct it. Documentation for earlier versions of gems can properly be found on the correct version page at rubygems.org.
We use semantic versioning:
- Major number bumps for incompatible changes (2.3.1 ==> 3.0.0)
- Minor number bumps for new features (2.3.1 ==> 2.4.0)
- Point number bumps for bugfixes (2.3.1 ==> 2.3.2)
Bugfix versions are not individually listed below but the link should take you to the latest bugfix version in each feature release series. Thus the link for a 3.4.x series might actually take you to version 3.4.2 - its latest bugfix.
NOTE: the version numbers of the different components in the Hydra stack (HydraHead, ActiveFedora, OM, Solrizer ...) are NOT synchronized.
One of the challenges of building a functioning Hydra stack has been knowing which versions of the various gems involved work together successfully. The Hydra gem (at the top of the 'optional gems' section) now provides this assurance. Instead of needing to identify and then list all the various gems in your Gemfile, instead add:
gem 'hydra', require: 'hydra6'
This will cause a complete, basic set of currently supported, compatible gem versions to be installed for you together with their dependencies.
