AG_Object: Introduce numerical class IDs and *_ISA() macros.
AG_Object: New function AG_ObjectFreeChildrenOfType().
AG_Radio: New HOMOGENOUS option to divide space equally between items. Thanks Stephen!
AG_StyleSheet: New CSS selectors E > F. Child widgets are now addressable by instance name (e.g., AG_Combo > "trigger") or class name (e.g., AG_Combo > AG_Button).

AG_Surface: Make the AG_SURFACE_TRACE flag useful for tracing surface operations such as blits, copies / conversions and mapping to widgets (needs --enable-debug-surfaces).
AG_Text: Expand the list of standard font sizes to 32 sizes. Added fractional sizes between 7.0 and 13.0.
AG_Text: Expanded font adjustments to include subpixel alignment corrections for all 32 standard sizes. The table now covers over 150 popular open-source fonts. Adjustments allow different fonts to align with pixel-perfect accuracy.
AG_Text: Added OS/2 metrics and Unicode range information to the AG_Font structure.
AG_Text: Utilize OS/2 metrics typoAscender and typoDescender where available.

It can be used for condensing or removing typographical spacings so that individual glyphs (for example "Geometrical Shapes") can be aligned precisely inside widget controls.
AG_Textbox / AG_Editable: Let AG_Textbox (and other containers) manage clipping so that text can be allowed to overflow out of the AG_Editable and out over the padding of its container widget.
AG_Editable: New option NO_CLIPPING to allow overflow beyond the widget's allocated area (for container widgets which implement their own clipping).
AG_Tlist: Draw lines to express the relationship between tree items.
AG_Tlist: New function AG_TlistScrollToSelection().
AG_Tlist: New option AG_TLIST_EXPAND_NODES. Display nodes (items with children) initially in expanded state.

MAP: Introduce dynamic Map Objects with MAP_Object. Map Objects coexist with static Map elements and are embedded with the serialized MAP. Nodes refer to MAP_Object instances using an intermediate MAP_Location structure (which adds per-node flags, z-coordinate, height, layer and neighbor information). More than one MAP node may refer to a given MAP_Object.
MAP: New functions MAP_DuplicateLocation(), MAP_NodeDelLocation(), MAP_NodeDelLocationAtIndex().
MAP: Added height (h) and z-coordinate (z) attributes to MAP_Item. Introduce MAP_Item classes.
MAP: Added Undo/Redo and History Buffer to Map Editor. New function MAP_ClearHistory().
MAP: Added validity tests to MAP_Node and MAP_Item.

AG_Text: Removed AG_UnusedFont() and the reference counter in AG_Font.
Changed
Ctrl + Mouse Wheel may now be used to change the zoom level on a window.

AG_Surface: In AG_SurfaceCopy(), add an optimized case for sources surfaces in <= 8-bpp.
AG_Surface: In AG_SurfaceCopy(), add an optimized case for grayscale source surfaces.
AG_Tlist: Improved appearance and typography fixes. Improved performance of the renderer using state-dependent opaque labels to avoid the need for blending in draw().
AG_Tlist: Now applies the "padding" attribute on a per-item basis.
AG_Tlist: AG_TlistSetCompareFn() now returns a pointer to the previous compare function.
