Release notes for WordStar 7.0 inlines, beginning with ER 649
(dated 4/1/92), through 690 (11/24/92).  

Revision D covers ERs 689 and 690.  688 is missing, which was 
the final ER of Revision C, in which the revision was bumped 
from Revision B and the bugs resulted in $TOC and $INDEX.

("ER" is "Engineering Release.")
