News in 5.3.0, 2021-12-08
-------------------------

This is a development release as we progress towards GNOME 42. It is
not a stable release and is intended for testing purposes.

 * Documentation has been updated to use gi-docgen.
 * Style schemes now support the <metadata> tag similar to languages.
   This can be used by style schemes to denote if they are light or dark
   mode and a relative scheme for use when desktop dark mode preferences
   have changed.
 * Selections for most style schemes bundled with GtkSourceView are now
   translucent and do not modify the foreground color. This performs very
   well now that we have GL based rendering in GTK.
 * The Vala bindings have moved from the Gtk namespace to the GtkSource
   namespace to match the bindings in all other languages. While it is
   unfortunate that this has happened after 5.0, it is still early enough
   that we can avoid having to maintain a clashing namespace with Gtk.
 * A new Vim emulator in the form of GtkSourceVimIMContext. This can emulate
   basic features such as Normal, Insert, Replace, Visual, Visual Line, and
   Command Bar modes. Additionally, many Vim-style motions and text-objects
   are supported. Registers, Marks, and Jumplists are also partially suppored.
   The + and * registers can be used to integrate with both the system and
   primary GDK clipboards. Various commands are available in teh command bar
   such as nohl, set, :s, :join, and more.
 * Updated language specs: rst.lang, c.lang, cpp.lang, vala.lang, spice.lang,
   lean.lang, and yara.lang.
 * Updated style schemes which improve the quality of output when used with
   non-standard GTK themes.
 * A new GtkSourceStyleSchemePreview widget.
 * The GtkSourceStyleSchemeChooserWidget now uses GtkSourceStyleSchemePreview
   to display style schemes.
 * Improve autocompletion styling when used with libadwaita.
 * Improvements to cell alignment in the gutter particularly useful when
   the CSS line-height attribute is used.
 * Many fit-n-finish improvements to GtkSourceMap.
 * The gutter line renderer now adapts to more situations where it will
   need to redraw based on highlight-current-line.
 * Build system improvements.
 * Translation updates.
