- Now all color related options and themes color definition have same
semantics. They can either be a table containing values like bg,fg,gui
or a string. When it's a string it's treated as a highlight group name
and newly created group is linked to that group.
- Using string values to define foreground colors in options like
color_error/color_added in diagnostics and diff component has been
deprecated.
- Added a decent way of notifying affected users of deprecations and
breaking changes.
