xcb-proto

<import>xproto</import> was explicitly
added to extensions that use xproto. "union" was
changed to "xidunion" for XID unions like DRAWABLE
and FONTABLE, so that the code generator can more
easily declare these XID unions as integer
typedefs rather than unions. Structures attempting
to provide C type safety were replaced with CARD32
typedefs. render.xml now describes
CompositeGlyphs* as taking lists of BYTE, rather
than lists of unions of structures of lists. The
caller must construct an appropriate sequence of
glyph elements. XCB didn't properly handle the
previous definition.

shape_op and shape_kind were renamed to drop the
"shape_" prefix, since otherwise these types end
up as xcb_shape_shape_{op,kind}_t. Leading
underscores are removed from enums in the GLX
protocol description. XML-XCB protocol
descriptions were moved to /usr/share/xcb, with
extension descriptions no longer relegated to an
extensions/ subdirectory. The single monolithic
GIT repository was split into individual
per-project repositories. A tool called git-split
was written to accomplish this.
