import	import was broken in 7.3.0 in the native Wind32 version when used inside contexts (i.e. odbc.lsp)	7.3.1	7.3.1	November 10th, 2003
contexts	contexts now can be assigned to variables and referenced during runtime, i.e. contextVar:varName with late binding of contextVar with varName during program execution.. New possibilities of OO programming and lexically scoped programming: See new chapter in the users manual about "Programming with context objects" and new function new, which can be used for copying and instantiating contexts from other contexts or templates. Stronger separation of contexts from context MAIN, only primitive symbols, context symbols, true, nil, ? and @ are inherited unless make global with global Avoids confusion through overwriting of variables depending on sequence of loading contexts and MAIN. All symbols for primitives, context symbols, true, nil, ? and @ are now protected and only can be changed with constant.	7.3.0	7.3.0	November 8th, 2003
new	copies contexts, helps using contexts a objects, which can be instantiated from a template context.	7.3.0	7.3.0	November 8th, 2003
global	new function to make variables in MAIN visible in all contexts (this was the default previously	7.3.0	7.3.0	November 8th, 2003
static in lambda expression	are not available anymore, use contexts, which are also lexically scoped, as objects instead.	7.3.0	7.3.0	November 8th, 2003
set-nth	like former replace-nth but multidimensional like nth, i.e.: (set-nth 1 2 0 '(1 (a b (c d))) 'x) => (1 (a b (x d))) the replaced expression can be found in $0: $0 => c	7.3.0	7.3.0	November 8th, 2003
nth	now can take multiple indices, i.e.: (nth 1 2 0 '(1 (a b (c d)))) => c good for working with matrices or sparse matrices out of bounds indices return the last element in dimension.	7.3.0	7.3.0	November 8th, 2003
chop	now also works on lists	7.3.0	7.3.0	November 8th, 2003
replace-nth	equivalent to the new set-nth now also uses the system variable $0 for the old element, i.e: (set 'lst '(1 2 3 4)) (replace-nth 1 lst (+ $0 1)) lst => '(1 3 3 4) now returns the changed list instead of the old expression found (which is now in $0), now checks also for missing last argument.	7.3.0	7.3.0	November 8th, 2003
replace-assoc	now also uses the system variable $0 for the old list, which can be reused in the replacement expression, i.e: (set 'lst '((a 1)(b 2)(c 3))) (replace-assoc 'b lst (list 'b (+ 1 (last $0)))) lst => ((a 1)(b 3)(c 3)) now returns the changed list not the replaced element,which now is in $0.	7.3.0	7.3.0	November 8th, 2003
remove	now returns the changed list and the number of removed elements in $0	7.3.0	7.3.0	November 8th, 2003
replace	now returns changed list or string for changed list count of replacements in $0 count for string replacements is not available any more (could be handled in replacement expression in a user written counter), now checks also for missing last argument. Fixed stack overflow after 2048 replacements.	7.3.0	7.3.0	November 8th, 2003
format	now checks for correct number of arguments and well formed format string, it will not crash anymore on mismatch of number and type of parameters	7.3.0	7.3.0	November 8th, 2003
constant	symbols protected with constant now also get saved with constant	7.3.0	7.3.0	November 8th, 2003
set, setq, set!, constant	return current value of the variable set, when last right-value is missing, i.e.: (set 'x 123) (set 'x) => 123 Useful when using 'constant' for putting protection on already assigned symbols. When using multiple parameter-value pairs it refers to the last parameter.	7.3.0	7.3.0	November 8th, 2003
infix.lsp	new module for parsing infix expressions i.e: (INFIX:xlate "(3 + 4) * (5 - 2)") => (mul (add 3 4) (sub 5 2))	7.3.0	7.3.0	November 8th, 2003

newLISP-tk	Uninitialized memory in writeStreamStr() caused problems when running newlisp-tk and transferring bigger string buffers. win32_fprintf() did not work right for buffers > 2048, which caused problems in browsing bigger buffers in newLISP-tk. These bugs had been around since version 6.5.18, but only surfaced when dealing with bigger string buffers and in the newLISP-tk environment. On the Win32 newLISP-tk version there are still limitations when evaluating edit windows with more than ~24Kbytes of content. This should never be a problem when editing function definitions, but could be a limitation when editing data lists bigger than 24K. Those lists or strings should be edited in a different editor outside the newLISP-tk environment and when on Win32.	7.1.4	7.1.4	September 7th, 2003

OSX, LINUX	surpression of some compiler warnings in Mac OSX compile makefile for linux has strip turned on and readline support was not the default	n/a	7.1.3	September 4th, 2003
[text] ... [/text]	[text] and [/text] can be used as string limiters for large unprocessed text regions, i.e. in CGI for HTML text, or any other purpose where text might be big and unprocessed.	7.1.0	7.1.0	August 29th, 2003
parse, search	can now take regular expressions as break string / search patterm	7.1.0	7.1.0	August 29th, 2003

installer for Win32	moved to version 5.4 of Freewrap for making the newlisp-tk.exe, which is now doubled in size because 5.4 doesn't compress anymore (see Freewrap docs), but avoids problems installing on some systems.	n/a	7.0.4	February 3rd, 2003
pop3.lsp, smtp.lsp, httpd example file changes/fixes	Improved Id's for the sort mail files, contributed by Bob 'CaveGuy'. Added better reporting for (set 'debug-flag true). Changes for eliminating deprecated functions.	7.0.1	7.0.1	October 25th, 2002

prettey printing improved	frixes for pretty printing quoted objects and empty iterators	7.0.1	7.0.1	October 25th, 2002
`slice`	collapses functionality of `sublist` and `substring` into one polymorph function. Thanks to Eddie R. for this great idea. The old `sublist`and `substring`now point to `slice.` They are deprecated but can still be used for some versions to come.	7.0.1	7.0.1	October 25th, 2002

`setq, set!`	new functions `setq/set!`, like set but don't need quoted variables and also take mutiple arguments. Note, that old `init.lsp`'s should be updated, becuase contains macro for setq.	7.0.1	7.0.1	October 25th, 2002
`set`	set now can take multiple arguments	7.0.1	7.0.1	October 25th, 2002
`constant`	new function `constant` to protect symbol contents from changing	7.0.1	7.0.1	October 25th, 2002
`NaN`	`NaN` can now be put into a variable for comparison. In mixed arithmetik using integer operators `NaN` is taken as 0. `NaN` caused crashes when used in Win32 in calculations. Division by zero now causes math exception in all versions (previously `Inf` in Unix versions). In mixed arithmetik using integer operators NaN is taken as 0. DOMAIN error messages in the Win32 versions are now silenced. Thanks to Bob 'CaveGuy' for helping to clean up `NaN` handling.	7.0.1	7.0.1	October 25th, 2002
