+** New `read' implementation in Scheme
+
+The new `(ice-9 read)' module implements a reader, in Scheme.  Compared
+to the C reader (which still exists for bootstrapping reasons), the new
+implementation is more maintainable, more secure, more debuggable, all
+while faithfully reproducing all quirks from Guile's legacy reader
+implemented in C.  Also, the Scheme reader is finally compatible with
+suspendable ports, allowing REPL implementations to be built with
+lightweight concurrency packages such as the third-party "Fibers"
+library.  The Scheme implementation is currently about 60% as fast as
+the C implementation, and we hope to close the gap over time.  Bug
+reports very welcome.
+
+** Scheme compiler uses `read-syntax' for better debugging
+
+The new Scheme reader also shares implementation with the new
+`read-syntax' procedure, which annotates each datum with source location
+information.  Guile's compiler can use this to provide better
+source-level debugging for Scheme programs.  Note that this can slightly
+increase compiled file sizes, though this is mitigated by some assembler
+optimizations.
+
+** Syntax objects record source locations
+
+When compiling a file that defines a macro, the output will usually
+include a number of syntax objects as literals.  Previously, these
+literals had no source information; now they do.  This should improve
+debugging.
+
+** Optimized run-time relocations
+
+The code that patches references between statically-allocated Scheme
+data has been optimized to be about 30% shorter than before or so, which
+can significantly decrease compiled file size and run-time
+initialization latency.
