• 38e9d8b Add docblock in crumbs_example_CrumbsMultiPlugin_ListOfNews

Fixed #2072839: Regression: taxonomy.termReference.* plugins have been renamed.

Bug fixes:
A very obvious fix that *should* have made it in beta5, but didn't make it.
See #2064183-10: Error message + not working

Fix #2064183: Error message + not working
asort() expects parameter 1 to be array, null given in crumbs_MultiPlugin_EntityFindSomething->initWeights()

Bug fixes:
- Fix serialization / cache problem in home_title plugin. #2019337: crumbs.home_title not working
- Probably bug fix in og.2 plugin
- Discard results from disabled plugin keys

UI changes:
- Weights config page now called "Plugin weights".

Code style, architecture:
- Plenty of docblock comments with type hints added.
- Plenty of changes that make the IDE happy.
- Use injected router object, instead of Drupal functions (might help us with unit tests in the future, dunno)
- Some classes moved around and renamed.
- Use generic crumbs_MultiPlugin_EntityParent for nodes and taxonomy terms, instead of having dedicated classes. Keep the dedicated class for users.
- New interfaces for plugins with findParent() and findTitle().
- New interface crumbs_PluginInterface for both multi and mono plugins.
- Remove unused methods and functions.
- Some dpm() and console.log etc removed.
- Reusable containers for plenty of stuff (might be a bad idea)

Bug fixes:
- Fix the textual weights form that was broken (only available with crumbs_labs)
- some intermediate fixes
- Front link should link to frontpage (empty path), not to 'node'. See #2044949: how to prevent Crumbs from adding /node to the front page link?

API:
- Introduce crumbs_InjectedAPI_hookCrumbsPlugins::routeMonoPlugin() and ::routeMultiPlugin(), for plugins that are restricted to a specific route. This way people can avoid the stupid method suffix to indicate the route.

Features:
- Breadcrumb titles for views with contextual filters
- Weights tabledrag form: Distinct section for "Disabled by default."
- New experimental weights configuration form, only available with crumbs_labs.

7.x-2.x awesomeness

Second alpha release..

Nice new tabledrag form for weights configuration!

Hotfix for #1844584: Notice: Undefined index: link_options em theme_crumbs_breadcrumb_link(); Recoverable fatal error: Argument 3 passed to l()

Hotfix release to not horribly break on og-7.x-2.x.
See #1819300: Support both branches of Organic Groups: 7.x-1.x and 7.x-2.x

Support for commerce_product_page with product/%

Fix the bug in #1698034: Call to undefined method _taxonomy_CrumbsMultiPlugin_termReference_user::_findParentCandidates()

Brand-new token-based parent path setting per node type.

It is good enough for a stable, I think.

- basic support for themekey, yeah! See #1045524-5: Deep theme switching with Crumbs + Themekey.
- some bug fixes
- some comments love
- lib files renamed to .php instead of .inc, to conform with latest xautoload (and ultimately be closer to psr0)
- admin.inc and debug.inc moved into admin/ subfolder
- taxonomy now picking the deepest terms first
- require php 5.2 instead of 5.1

Fix the "undefined index" bug in crumbs.admin.inc
