0.8.9
* default-backend.lisp, circularities.lisp: Updated the serialization of lists to fix the bug reported by gugamilare@gmail.com.
OPTIMIZATION: T and NIL are no longer stored as symbols but have custom serializers (which only writes out the type code)
FEATURE: Correct List Serialization. A new symbol *precise-list-storage* is now exported from CL-STORE. When bound to true
all lists will be serialized in as correct a manner as possible ensuring that shared list structure is correctly tracked.
The unfortunate downside to this is that, due to the recursive nature of the method, storing large lists will blow the stack.
This provides a workaround for a bug reported in November 2007 by szergling.

2007-01-22 Sean Ross <sross@common-lisp.net>
* utils.lisp, circularities.lisp, tests.lisp

create-serialize-hash, with-grouped-serialization, *grouped-store-hash*
and *grouped-restore-hash*.
* conditionalize some forms which were preventing ABCL from running the tests.

of CLISP with a MOP.
* default-backend.lisp: Fixed storing of long lists.
(Reported by and help by Alain Picard)

* utils.lisp: Removed awhen
* backends.lisp: Added a compatible-magic-numbers slot.

to find-backend (default false).
* default-backend.lisp: Changed simple-string storing
to keep the upgraded-array-element-type of the
restored string the same as the string which was stored.
This seems to give a performance boost (more in memory usage)
with SBCL and Lispworks.
* circularities.lisp: Stopped binding *stored-values*
and *restored-values* when circularity checking is inhibited.
* doc/cl-store.texi: Miscellaneous fixes.

2005-05-05 Sean Ross <sross@common-lisp.net>
* all: After much experimentation with Lispworks I

test as it was incorrect.

2005-03-24 Sean Ross <sross@common-lisp.net>

of restore-error and store-error.

test to determine whether or not a string contains unicode
characters.

Version 0.5 Release.
* utils.lisp, package.lisp: Took a lesson from the MOP
and changed serializable-slots to call the new GF
serializable-slots-using-class.

from Thomas Stenhaug which adds more comprehensive package
storing.

2005-02-14 Sean Ross <sross@common-lisp.net>
* default-backend.lisp: Applied patch from Thomas Stenhaug
to default null superclasses of a restored class to
standard-object as this caused errors in Lispworks.

2005-02-11 Sean Ross <sross@common-lisp.net>
New Magic Number for cl-store-backend.
* default-backend.lisp, acl/custom.lisp, lispworks/custom.lisp
* sbcl/custom.lisp, cmucl/custom.lisp:
Changed storing of floats to be compatible between implementations
while ensuring that NaN floats and friends are still serializable.
* backends.lisp, plumbing.lisp:
Added concept of backend designators which can be a
symbol (the backend name) or the backend itself. These are
acceptable replacements for a backend object
to store, restore and with-backend.
Completely changed argument order for generic functions
to ensure that backends are the first argument.
* ecl/mop.lisp: Added support for ecl.
* plumbing.lisp: Removed multiple-value-store (I don't really
see the point of it).
* backends.lisp: Changed the working of object restoration
from functions in a hash-table (restorer-funs of a backend)
to generic functions specialized on backend and a symbol,
removed find-function-for-type.
* plumbing.lisp: Changed the handling of the stream-type
of backends to be any legal type designator since it's
only used when opening files.
* backends.lisp: Both defstore-? and defrestore-?
can take an optional qualifer argument.

2005-02-03 Sean Ross <sross@common-lisp.net>
* default-backend.lisp: Fixed hash-table restoration,

is a symbol but treats it as a function designator.
* default-backend.lisp: Added various declarations
to help improve speed.

2005-02-01 Sean Ross <sross@common-lisp.net>
* various: Large patch which has removed pointless
argument-precedence-order from various gf's, added the
start of support for ecl, renamed fix-clisp.lisp file to
mop.lisp, and changed resolving-object and setting
to use delays allowing get-setf-place and *postfix-setters*
to be removed.

2004-12-02 Sean Ross <sross@common-lisp.net>
* sbcl/custom.lisp, cmucl/custom.lisp: Changed the evals when restoring
structure definitions to (funcall (compile nil ...))

with symbols with no home package.
* sbcl/custom.lisp: Support for structure definitions from defstruct.
* tests.lisp: Tests for structure definitions.
* circularities.lisp: Optimization for referrers and values-object's.
Added *store-hash-size* and *restore-hash-size* which can be bound
to reduce the calls to rehash which conses like crazy.
Added *check-for-circs* which can be bound to nil to stop
checking for circularities which reduces consing drastically but objects
will not be eq and will hang on circular objects (see README).
* default-backend.lisp: New Magic Number ,again.
Cater for SB! package names for built-in function names
in SBCL.
