Build 5G67 presents substantially richer support for handling text: for the
first time, arbitrary and manipulable strings of text are first-class values
in Inform. Substantial internal reforms, notably a new implementation of
the type-checker (now the third such), lead also to other improvements:
notably the ability to store and play back entire actions, and a form of
boolean type for the first time - "truth state". Finally, Inform is now
available for three new operating systems: Mac OS X Leopard (10.5), and
Fedora and Ubuntu Linux. We welcome Philip Chimento to the Inform team as
the author of the Gnome user interface for Linux.
