This file contains release notes for version 0.94 of Wood.

New features since 0.93
-----------------------
Wood works in MCL-PPC 3.9. Files saved with earlier versions of
Wood in MCL 2.0 or 3.0 can be read by Wood 0.94 in MCL-PPC.
I have not tested that Wood 0.94 still works in MCL 3.0 or MCL 2.0.

Hash tables are now converted to/from the MCL 2.0 representation.
This means that a hash table that was saved in a Wood file by
MCL 2.0.1 will be readable in MCL 3.0 or MCL-PPC 3.9 and
vice-versa. It also means that a hash table that was written
in a Wood file by MCL 3.0 and version 0.93 or earlier of Wood
will no longer read correctly. If you have this problem, ask
and I'll make a patch for you. Note that I'm referring to
saving a Common Lisp hash table, not the "hash tables" created
by p-make-hash-table, which are really a thin skin over btrees.

You can p-store/p-load extended (16 bit character) strings.

A Wood file can be opened read-only. As with any other disk file,
multiple applications can open the same Wood file in read-only mode.
Any attempt to write to a Wood file that was opened read-only
will signal an error. See the :READ-ONLY-P keyword to OPEN-PHEAP
in "wood.doc".


Mod Histories
-------------
block-io-mcl.lisp
;; 03/09/96 bill Eliminate LAP for ppc-target

btrees.lisp
;;; 03/26/96 bill  Don't use %schar in %btree-search-node, MCL-PPC type checks it.
;;; 03/21/96 bill  Specify element-type of base-character to make-string calls
;;;                Add an optional swap-space-in-k arg to time-btree-store & time-btree-read

disk-cache-accessors.lisp
;; 03/20/96 bill Make work in MCL-PPC

disk-cache-inspector.lisp
;; 03/21/96 bill %typed-uvref -> aref inside a lying declaration.

disk-cache.lisp
;; 03/27/96 bill Dylan changes add a :read-only-p keyword to open-disk-cache

disk-page-hash.lisp
;; 03/21/96 bill (make-array ... :INITIAL-ELEMENT NIL) in make-disk-page-hash-table-vector

load-wood.lisp
;; 03/21/96 bill  compile-and-load resignals any error it doesn't recognize
;; 03/09/96 bill  say ccl::*.fasl-pathname* instead of ".fasl".

persistent-heap.lisp
;; 04/04/96 bill  Handle hash tables.
;;                Revert p-load-header. New code renamed to p-load-arrayh.
;; 03/29/96 bill  #+ppc-target for the new p-load-header def.
;;                p-load-struct passes true value for the new struct-p
;;                arg to p-load-gvector. This makes loading a struct
;;                that references itself work again.
;; 03/27/96 bill  :read-only-p keyword for open-pheap (from Dylan).
;; 03/22/96 bill  Make it work on the PPC.
;;                This mostly involved mapping the new typecodes to/from the old subtypes
;;                and dealing with the change in complex array/vector headers.
;;                New:
;;                  *wood-subtype->ccl-subtag-table*, *ccl-subtag->wood-subtype-table*,

;;                Changed:
;;                  wood->ccl-subtype, ccl->wood-subtype,
;;                  p-load-header, immediate-object-p, %p-store-object
;; 03/21/96 bill  uvref-extended-string, uvset-extended-string and other support for 2-byte strings.
;; 09/12/95 bill  setf method for p-stored?

wood-gc.lisp
;; 03/21/96 bill (make-string ... :element-type 'base-character)
