Fullcalendar: v5.10.0 Release

• feature: WAI-ARIA improvements:
  • toolbar (#6521)
  • human-readable title attributes on all buttons. new options:
    • buttonHints
    • customButtons.hint
    • viewHint (ex: $0 view -> "month view")
  • aria-labelledby attribute connecting view-title with view-container
  • event elements (#3364)
  • previously, only events with an event.url property were tabbable by the end-user. now, events without urls can be made tabbable by enabling event.interactive or by enabling the calendar-wide eventInteractive option.
  • when focused, pressing enter/spacebar will trigger an eventClick
  • more-links and popover (#6523)
  • human-readable title attributes on "+more" links via new option moreLinkHint
  • when focused, pressing enter/spacebar will open popover
  • aria-controls/aria-expanded attributes connecting link to popover
  • aria-labelledby attribute connecting popover-title to popover
  • aria-label attribute describing "X" close icon via new option closeHint
  • pressing escape key closes popover
  • nav-links (#6524)
  • human-readable title attributes on all navLinks via new option navLinkHint
  • when focused, pressing enter/spacebar will trigger navLinkClick
  • table-based views (#6526)
  • all cells within thead elements have been made into <th> tags
  • retrofit the necessarily non-ARIA-friendly table markup with role tags. the root table is a grid, children have been given rowgroup/row/columnheader/rowheader/cell, and non-functional table elements have been given presentation.
  • in timegrid views, the time-axis axis has been removed from the accessibility tree
  • list-view (#6525)
  • introduced a table-header specifically for screen readers. header cells label the time/event columns using the following new options: timeHint and eventHint
  • removed the "dot" column from the accessibility tree
• feature: date formatting option week now accepts 'long' if locale defines weekTextLong
• bugfix: timeline-view events hidden by eventMaxStack sometimes appear over other events (#6543)
• bugfix: daygrid event rendering with dayMaxEventRows and custom eventOrder can cause infinite loop (#6573)
• bugfix: content-injected html/domNodes as view-specific options don't clear when switching views (#6079, #6555)
• bugfix: more compliant CSS with Sass processors (#6564)
• locale: added si-lk (#6553)

HELP WANTED populating new options in locales (examples: es, en-GB) - buttonHints - viewHint - weekTextLong - moreLinkHint - navLinkHint - closeHint - timeHint - eventHint
