append, concat	append now is type polymorph working also on strings, this doubles the functionality of concat, which is now deprecated Thanks to Eddie Rucker for suggesting this change.	6.5.8	0.81	June 14th, 2002
find, replace	find and replace now have regular expression support, integration of regular expresions into some more functions may come in the future.	6.5.8	0.81	June 14th, 2002
Perl compatible regular expresssions	change from GNU regular expressions to Perl compatible regular expressions (PCRE: http://pcre.org ), 20-50 times faster and same code on all platforms (before 6.5.8 regex was part of the GNU Libc). Thanks to Steve Adams for pointing me to PCRE.	6.5.8	0.81	June 14th, 2002

time	(time expr) now works as a timer returning milli seconds needed to evaluate an expression. This is also more compatible how other Lisp's define 'time'. For old funcitonality of 'time' use (apply date-value (now))	6.5.0	0.81	May 28th, 2002
push	(push expr lst): now works even if lst does not contain a list. In that case old contents of lst gets deleted and initialized with () before pushing expr, this makes initialization of lists to '() before pushing on it unnecessary.	6.5.0	0.81	May 28th, 2002
nil, true	many changes for more consistent treatment of nil and true as boolean constants/symbols in conditional and boolean expressions. This did not prompt any code changes in the code shipped in newLISP dsitributions but may prompt changes in some other rare instances of code created by users. All conditional and boolean expressions containing: 'if, while, unless, until , not, or' should be checked for correct working. Both nil/true the constants and unevaluated nil/true as symbols should be treated equally.	6.5.0	0.81	May 28th, 2002
newlisp_manual.html	new chapter in newlisp_manual.html about 'purelisp' and consistency in newLISP on how 'cons', '()' and 'nil' work together redefining basic primitives like 'append', 'apply', 'reverse' and the type polymorph 'first', 'rest', 'last' and 'nth'	6.4.8	0.81	May 16th, 2002
link.lsp	fix for link.lsp on CYGWIN, generated program would only work when calling with '.exe. suffix. This is no longer necessary	6.4.8	0.81	May 16th, 2002
