2/24/99 (version 0.53)
Additions:
DEFINE-FINITE-TYPE and DEFINE-ENUMERATED-TYPE (in structure
FINITE-TYPES; documented in doc/utilities.ps and
doc/html/utilities.html.
Added CHAR-SOURCE->INPUT-PORT, CHAR-SINK->OUTPUT-PORT,
MAKE-STRING-OUTPUT-PORT, STRING-OUTPUT-SOURCE-OUTPUT to
the extended-ports structure.
The structure BYTE-VECTORS is the same as CODE-VECTORS with `byte'
replacing `code' in all the names. The underlying datatype is the
same for both, and uses `byte' when printing.
There is a new and much improved interface to C code, thanks to
Mike Sperber. It is documented in in doc/external.ps and
doc/html/external.html.
Bug fixes:
Session-data and user-context records are no longer in the fluid env.
Lexical environments can now be nested up to 65k deep.
,expand no longer prints `definition in expression context' warnings.
Added ARRAY? and SEARCH-TREE? to the array and search tree structures.
Flat environments work again.
Templates of the form `var ... ...' now work in syntax rules.
Reinstated caching of SCHEMIFY results to greatly reduce the space
used by debugging info.
Added argument checking to STRING->NUMBER and NUMBER->STRING.
Fixed space blow-up in LOAD.
Unused ports are closed more reliably.
Changes:
The heap, gc, and image code is now in three separate modules.
The symbol table is now held in a VM register.
Inlined SHOWING-FOCUS-VALUES into the main command loop and moved
the sentinal call to reduce the noise at the base of ,preview output.
The tables returned by MAKE-TABLE now use EQV? for comparison (instead
of EQ?). This makes these tables about 50% slower when numbers are
used as keys, but significantly more accurate.
Floating-point numbers are no longer double boxed.
The channels structure has been split into channels and low-channels.

- New, optional Makefile variable HOMEPAGE, specifies a URL for
the home page of the software if it has one.
- The value of HOMEPAGE is used to add a link from the
README.html files.
- pkglint updated to know about it. The "correct" location for
HOMEPAGE in the Makefile is after MAINTAINER, in that same
section.
