[dependabot-preview]

Bumps gretel from 3.0.9 to 4.3.0.

Changelog

Sourced from gretel's changelog.

Version 4.3.0

• Support generating aria-current attribute. It's disabled by default. See the readme for more info

Version 4.2.0

• Support generating JSON-LD structured data. See the readme for more info (via #26, thanks @​dkniffin)

Version 4.1.0

• Depends only railties and actionview, not rails (via #7)
• Include Gretel::ViewHelpers module in ActiveSupport.on_load(:action_view) block
• Fix ruby 2.7 keywords warning (via #24, thanks @​aki77)
• Fix multithreaded environment issue (via #13)
  • breadcrumbs.rb is now evaluated in a instance of Gretel::Crumbs::Builder. If you want to call methods from breadcrumbs.rb other than crumb, crumbs and crumb_defined?, you need to call it via full reference like Gretel::Crumbs.xxxx

Version 4.0.2

• The return value of breadcrumbs is html_safe now (via #22)
  • For the slim template engine users: You don't need to use == instead of = for breadcrumbs

Version 4.0.1

• Replaces data-vocabulary markup as google doesn't support it and now uses schema.org markup (via #17)

Version 4.0.0

• Support Bootstrap 4. See the :style option in the readme for more info
• CSS class for fragment link or span is now customizable. See the :fragment_class option in the readme for more info
• Drop support Ruby < 2.5
• Drop support Rails < 5.1
• Deprecated codes have been removed:
  • breadcrumbs is no longer accept block, use tap instead
  • breadcrumbs is no longer accept style: :default, use style: :inline instead
  • breadcrumbs is no longer accept :show_root_alone option, use :display_single_fragment option instead
