(Modifications are listed in order from most recent to least recent.)

New in release 0.5.11 (since release (0.5.10)

* NT_MAKEFILE has not been tested, but is probably close to working.
Feedback with diffs would help this become more stable.  Check the
Makefile to see how NT_MAKEFILE gets made (using sed).  I'll gladly
accept help in this area.

* Now uses gc4.5 Thanks to the work of Boehm et.al. for indirectly
making Marlais possible.

* make on <class> now requires debug-name (if specified) to be a
string, i.e., make (<class>, ... debug-name: "<class-name>", ... ).
It used to require a symbol, but it didn't work.  I suspect few were
using it in that condition.

* `block' is now partially supported with a single cleanup clause and
the afterward clause as proposed by Tim McNerney of Harlequin.
There's no support for exceptions in blocks yet.

* `as (<class>, <collection>)' repaired.

* Defining a method for `object-print (<stream>, <class>)' causes the
listener to print instances of <class> using that method.

* Fixed array indexing bugs.

* Fixed bug in method caching.

* Removed use of C auto array in L*Loops class precedence algorithm.

New in release 0.5.10 (since release (0.5)

* Modified class precedence list mechanism to use the L*Loops algorithm
	of Ducournau, et. al. (OOPSLA '94 pg. 164) as default mechanism.

* Fixed CLOS precedence list computation algorithm.

* Added method caching strategy to attempt to improve performance of
	GF lookup.

* Fixed many errors in init.dyl collection methods (such as add, add!, etc.).
	Most of them assumed that the finished state was always #f.
	Also modified init.dyl to use while: and until: in `for'.

* Modified deque iteration mechanism to use non-boolean state.

* Fixed foo[i1, i2, ..., in] to be equivalent to aref (foo, i1, i2, ... in)
	and added element and element-setter methods for a single
	int index on an array.

* Fixed make so that after slot initialization *all* default-initializers
	are passed to initialize.

* Updated format two-char sequences to match C-style formats of DIRM pg. 152.

* Fixed erroneous behavior of `case' and `select' on empty branches.

* Added support for keywords until: and while: in `for'.

* Made function-specializers work with gfs.

* Fixed error in handling return values associated with Tail Recursion.

* Fixed problem in lexer with vector literals like #[sun:, mon:] generating
errors.

* Fixed problems with list literals.

* Added Tail recursion

* Function specializers now works on GFs too.

* Now support #f setter-name spec. in class definition (to force no setter)

* Fixed array iteration protocol.

* Prefix style setters work, i.e.

	(set! (slot object args) new-value)

* Fixed value return specifications.

* GF method specializers are now required to match the GF specializers.

* Setters now work in prefix mode.

* Now support new #key parameter default value initialization (as
specified in DIRM errata list).

* Setters are now DIRM compliant.

* Fixed problem with slot init-value getting reset when specified as
	init-keyword argument.

* Added floor, ceiling, round, floor/, ceiling/, round/, and truncate/.

* Added <object-table> and made it the implementation class for <table>.

* Fixed applicable-method? to handle GFs as well as methods.  Also
fixed it not to check for extraneous keyword parameters if the
argument is a GF rather than method.

* Setter methods specialize the argument parameter to the appropriate
type, providing type-safe slot values.

* Slot type evaluation is now lazier.  Slot types and getter/setter
methods are now created at the time of first instance initialization.
This supports forward reference to other classes.

* Some initial support for debugging.  Invocation of error causes the
interpreter to execute a debuffer read-eval-print loop that supports
inspection of environment and call stack.

* Added
	show-bindings(i :: <integer>) => ()
which prints the

* Added 
	print-stack() => ()
which prints the owner for each active frame

* Modified frames to include an "owner" which is a subprogram or symbol

* infix loads no longer echo when -e flag is specified.

* Fixed error with string concatenation i.e.  "abc" "def" now evals
to "abcdef" rathern than Bus Error.

* Fixed values to work correctly with no arguments.

* Fixed bindings rule to handle #rest variable correctly

* Fixed make (gf == <generic-function> ...)

* Fixed fill! for mutable sequences

* Fixed apply (to handle single collection arg)

* Fixed broken #all-keys key parameter specification.

* Added function
	system (<string>) => <integer>
to allow execution of shell commands.

* Modified init definitions of all mapping functions to use
forward-iteration-protocol.

* init.dyl is now infix.

* Modified forward-iteration-protocol to return methods rather than generic
functions.  This improves performance of `for', and all mapping functions.

* Now supports keyword parameters with unmatched keyword and variable names.
as described on DIRM pg. 52.

* Parses dylan file headers and pays attention to module specification

* Slightly better parsing and error handling.

* marlais.el lisp mode

* Half way reasonable support for modules.
