This release is a major reform of a now-mature language which is widely used,
and it has been over three years in the making. Text handling is better,
Inform can now generate adaptive grammar, there's real number support, and
a new Public Library of extensions is being introduced. There are significant
improvements in the user interface for Mac OS X. Around 500 bug reports had
been filed on the core software since build 6G60, and every one of them has
been resolved.
