This release is to ensure fully working popovers in BS4. Issue is that the Bootstrap CDN\n *\t\tdoesn't actually have the whitelist property, so developing against it is basically useless :(\n *\t- Improved BS4 support and template switching. Changed options for framework vs template.\n *\n * Changes from 0.7:\n *  - Fast release to fix breaking change in Bootstrap 3.4.1, fixes this issue: https://github.com/sorich87/bootstrap-tour/issues/723#issuecomment-471107788\n *\t\tIssue is caused by the BS sanitizer, to avoid this reoccurring the \"sanitizeWhitelist:\" and \"sanitizeFunction:\" global options added\n *\n * Changes from 0.6:\n *\t- Fixed invalid call to debug in _showNextStep()\n *\t- Added onPreviouslyEnded() callback: https://github.com/sorich87/bootstrap-tour/issues/720\n *\t- Added selector to switch between bootstrap3 and bootstrap4 or custom template, thanks to: https://github.com/sorich87/bootstrap-tour/pull/643\n *\n * Changes from 0.5:\n *\t- Added \"unfix\" for bootstrap selectpicker to revert zindex after step that includes this plugin\n *  - Fixed issue with Bootstrap dialogs. Handling of dialogs is now robust\n *  - Fixed issue with BootstrapDialog plugin: https://nakupanda.github.io/bootstrap3-dialog/ . See notes below for help.\n *  - Improved the background overlay and scroll handling, unnecessary work removed\n\n\n ---------\n\n\n This fork and code adds following features to Bootstrap Tour\n\n 1. onNext/onPrevious - prevent auto-move to next step, allow .goTo\n 2. *** Do not call Tour.init *** - fixed tours with hidden elements on page reload\n 3. Dynamically determine step element by function\n 4. Only continue tour when reflex element is clicked using reflexOnly\n 5. Call onElementUnavailable if step element is missing\n 6. Scroll flicker/continual step reload fixed\n 7. Magic progress bar and progress text, plus options to customize per step\n 8. Prevent user interaction with element using preventInteraction\n 9. Wait for arbitrary DOM element to be visible before showing tour step/crapping out due to missing element, using delayOnElement\n 10. Handle bootstrap modal dialogs better - autodetect modals or children of modals, and call onModalHidden to handle when user dismisses modal without following tour steps\n 11. Automagically fixes drawing issues with Bootstrap Selectpicker (https://github.com/snapappointments/bootstrap-select/)\n 12. Call onPreviouslyEnded if tour.start() is called for a tour that has previously ended (see docs)\n 13. Switch between Bootstrap 3 or 4 (popover methods and template) automatically using tour options\n 14. Added sanitizeWhitelist and sanitizeFunction global options\n 15. Added support for changing button texts\n\n --------------\n\t1.

Scrolling the browser window does not cause the tour step to reload.\n\n\t\t\tIMPORTANT: orphan steps are stuck to the center of the screen. However steps linked to elements ALWAYS stay stuck to their element, even if user scrolls the element & tour popover\n\t\t\t\t\t\toff the screen. This is my personal preference, as original functionality of tour step moving with the scroll even when the element was off the viewport seemed strange.\n\n---------------\n\t7.

Handle Dialogs and BootstrapDialog plugin better https://nakupanda.github.io/bootstrap3-dialog/\n\t\t\tPlugin makes creating dialogs very easy, but it does some extra stuff to the dialogs and dynamically creates/destroys them. This\n\t\t\tcauses issues with plugins that want to include a modal dialog in the steps using this plugin.\n\n\t\t\tTo use Tour to highlight an element in a dialog, just use the element ID as you would for any normal step. The dialog will be automatically\n\t\t\tdetected and handled.\n\n\t\t\tTo use Tour to highlight an entire dialog, set the step element to the dialog div. Tour will automatically realize this is a dialog, and\n\t\t\tshift the element to use the modal-content div inside the dialog. This makes life friendly, because you can do this:\n\n\t\t\t<div class=\"modal\" id=\"myModal\" role=\"dialog\">\n\t\t\t\t<div class=\"modal-dialog\">\n\t\t\t\t\t<div class=\"modal-content\">\n\t\t\t\t\t...blah...\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\n\t\t\tThen use element: myModal in the Tour.\n\n\n\t\t\tFOR BOOTSTRAPDIALOG PLUGIN: this plugin creates random UUIDs for the dialog DOM ID. You need to fix the ID to something you know. Do this:\n\n\t\t\t\tdlg = new BootstrapDialog.confirm({\n\t\t\t\t\t\t\t\t\t\t\t\t\t....all the options...\n\t\t\t\t\t\t\t\t\t\t\t\t});\n\n\t\t\t\t// BootstrapDialog gives a random GUID ID for dialog. Give it a proper one\n\t\t\t\t$objModal = dlg.getModal();\n\t\t\t\t$objModal.attr(\"id\", \"myModal\");\n\t\t\t\tdlg.setId(\"myModal\");\n\n\n\t\t\tNow you can use element: myModal in the tour, even when the dialog is created by BootstrapDialog plugin.\n\n\n----------------\n\t11.\tFix conflict with Bootstrap Selectpicker: https://github.com/snapappointments/bootstrap-select/\n\t\tSelectpicker draws a custom select.
