If I were to word this, it'd be something like:

GDB now supports specifying breakpoints in shared libraries that have
not yet been loaded.  If GDB cannot find a breakpoint location the
user specifies, it prompts for whether the breakpoint should be
deferred, pending a future shared library load.  If and when GDB
resolves the symbol, it replaces the pending breakpoint with a regular
breakpoint.  This feature is very useful for gcj java and sid debugging.

(Does it undo this pending->regular mapping when the shlib is unloaded?)
(Oops, somehow that sid comment slipped in. :-)
