It took a couple years, but I think we finally tracked down and fixed the segfault issue that was causing so many graphs to break during generation, or simply be entirely blank! We had a ton of great contributions this past year, and I'm glad to finally get them bundled up and shipped.

One big change is dropping support for Rails 3.2 and Rubies < 2.2; they're unsupported, not even receiving major security patches, so it was time. v1.6.0 /may/ still work with some of these versions, but consider them unsupported going forward.

I also added early support for Rails 6.0.0.rc1; its working in testing, but should be considered experimental. Patches welcome, and if needed updates will ship. I suspect we'll see additional bug reports as 6.0.0 reached final release, but if you have a Rails 6 project I encourage you to give it a try.

Lots of new stuff in 1.5.0! We've gotten Rails 5.x support in place, as
well as adding 2 new options. "clustering" will draw a box around models
contained in the same name space, helping to visually organize areas of
concern. "only_models_include_depth" - although awkwardly named - will
restrict the depth of graphing to the supplied value.

• New option of 'clustering' by namespace (#205)
• Support for 'only_models_include_depth' option (#219)
• Added basic support for non-Rails apps (#208)

• Fixes to tests (#210, #213)
• Various documentation fixes (#203, #212)

Changes since 1.2.0:

• Fixes a bug in sorting abstract classes (Issues #54, #88)
• Fixes a bug in OS detection for JRuby (and newer MRI Rubies, too)

• Fixed bug that prevented generation of diagrams on newer versions of OSX
• Added ability to store CLI configuration options in a config file, both a global version (in the user's home directory) as well as a per-project local versions
• Added a Code of Conduct for the project
