 While xkbcommon's API is somewhat derived from the classic XKB API as found
 in <X11/extensions/XKB.h> and friends, it has been substantially reworked to
-expose fewer internal details to clients.  The only supported API is available
-in <xkbcommon/xkbcommon.h>.  Any definition not in this header (including
-accessing internal structures through the old macros previously available)
-should be regarded as an implementation detail and is liable to change at any
-time.
+expose fewer internal details to clients.  The supported API is available
+in the <xkbcommon/xkbcommon-*.h> files. Additional support is provided for
+X11 (XCB) clients, in the xkbcommon-x11 library, <xkbcommon/xkbcommon-x11.h>.
 
-During its early development, xkbcommon does not promise API or ABI stability.
-Regardless, we will attempt to not break ABI during a minor release series,
-so applications written against 0.1.0 should be completely compatible with
-0.1.3, but not necessarily with 0.2.0.  However, new symbols may be introduced
-in any release.  Thus, anyone packaging xkbcommon should make sure any package
-depending on it depends on a release greater than or equal to the version it
-was built against (or earlier, if it doesn't use any newly-introduced
-symbols), but less than the next major release.
-
-xkbcommon 1.x will offer full API and ABI stability for its lifetime, with a
-soname of libxkbcommon.so.1.  Any ABI breaks will wait until xkbcommon 2.0,
-which will be libxkbcommon.so.2.
-
-The xkbcomp command-line tool has also been removed, although this will
-likely reappear in a later release.
