Version 0.84.0
==============

- HdyHeaderGroup:
  - Replace GtkHeaderBar as the child type by HdyHeaderGroupChild, and
    adjust the matching accessors. HdyHeaderGroupChild can hold a
    GtkHeaderBar, a HdyHeaderBar, and a HdyHeaderGroup, allowing to nest
    header groups.
  - Replace the 'focus' property by the 'decorate-all' property.
  - Add the update-decoration-layouts signal, used when nesting header
    groups.
- HdyHeaderBar:
  - Slight size request fix.
- Use the window node's radius instead of the decoration node's one to
  mask HdyWindow and HdyApplicationWindow.
- Make HdyAvatar, HdyHeaderGroup, HdySqueezer, HdyViewSwitcher,
  HdyViewSwitcherBar, HdyViewSwitcherTitle, and HdyWindowHandle final.
- Replace usage of (allow-none) by (nullable) or (optional).
- Translation updates:
  - Ukrainian
