-Changes in alpha 2.9.7 (since alpha 2.9.6):
-
-* Notable changes
-
-** Improve JIT code generation
-
-Native code for unlikely or expensive cases is now generated
-out-of-line, improving instruction cache utilization.  It makes things
-go faster!
-
-** Fix JIT bug preventing tier-up within loops
-
-Before, it was possible to see significantly better performance when
-forcing eager JIT compilation using the GUILE_JIT_THRESHOLD environment
-variable; see "Environment Variables" in the manual.  This was due to a
-bug that prevented tiering up to JIT code in some cases, and has been
-fixed.
-
-** `iota' in core and SRFI-1 `iota' are the same
-
-Previously, `iota' in core would not accept start and step arguments and
-would return an empty list for negative count. Now there is only one
-`iota' function with the extended semantics of SRFI-1.  Note that as an
-incompatible change, core `iota' no longer accepts a negative count.
+Changes in alpha 2.9.8 (since alpha 2.9.7):
 
 * Bug fixes
 
-** Fix recently introduced bug causing early abort if stdin is closed
+** Fix bug in which abort_to_prompt used an invalid stack pointer
 
+This bug manifested itself as a bootstrap compile error on some systems,
+notably Ubuntu 18.04 on x86-64, and was due to failing to recalculate a
+local variable after a possible stack relocation.
+
+** SRFI-35 does a #:re-export-and-replace on `&error'
+** SRFI-35 avoids compiler warnings for multiply-defined condition types
