+-------------------------
+
+GtkSourceView 5.2.0 is the release corresponding with GNOME 41.0 for
+GTK 4-based applications. We expect performance improvements when
+combined with GTK 4.4's NGL renderer, especially on HiDPI systems.
+
+Changes since 5.1.0
+
+ * Add support for drawing a highlight line between the gutter and
+   text area. kate.xml uses this to more closely match Kate.
+ * Python 3 is now preferred over Python 2.
+ * Fixes for moving words.
+ * A new scheduler API to help with background buffer work
+ * Improvements to YARA syntax.
+ * Translation updates.
+
