1. Version 0.6a (June 05 2002)

[Update] Improved mn8-mode for XEmacs. [AA]

[Update] Refactored the AST interpreter in order to allow multiple concepts to be interpreted simultaneously without synchronization blocks. [RP]

[Update] Refactored the output and error streams handling in order to allow different execution paths to output the results on different streams. This was needed to allow multiple MN8 scripts/concepts to be run concomitant inside the servlet engine. [RP]

[Fix] The and operation was not conditional. Now, it evaluates its right-hand operand only if the value of its left-hand operand is true. Fixes bug nr: NLNT155. [RP]

[Fix] The or operation was not conditional. Now, it evaluates its right-hand operand only if the value of its left-hand operand is false. Fixes bug nr: NLNT156. [RP]

[Add] New static methods (print and println) in Error concept to allow signaling on the error stream. [RP]

[Fix] $args parameter in MN8 scripts works again. Fixes bug nr: NLNT148. [RP]

[Fix] Attributes where case sensitive. Fixes bug nr: NLNT150. [AA]

[Fix] Fixed insert bug in Series and TypedSeries. Fixes bug nr: NLNT152. [AA]

[Fix] Fixed missing documentation for the System concept. [RP]

[Fix] Missing runtime attributes of the current data source in the where clause. Fixes bug nr: NLNT151. [RP]

[Update] Updated documentation for the URIHandlers. [SC]

[Update] A couple of new methods and operators for the Date concept. [RP]

[Add] Servlet for running MN8 concepts or scripts on a web server side. New ServletRequest, ServletSession, ServletResponse concepts. [RP]

[Fix] Can use HTML forms with post method. [AA]

[Update] Added methods to store forms and get stored forms in HTMLForm concept. [AA]

[Update] Added methods to control follow redirects on HTMLPage concept. [AA]

[Update] Added methods to handle responses on HTMLPage concept. [AA]

2. Version 0.5a (May 06 2002)

[Fix] The getConceptsAtPath method doesn't work. Fixes bug nr: NLNT145. [RP]

[Fix] The hasPath method doesn't work. Fixes bug nr: NLNT144. [RP]

[Add] The end of line separator now is configurable. The default value is system specific (Windows -\r\n, Mac - \r, Unix -\n) but can be overridden in mn8config.xml file by putting a bind element in the context element as follows: <bind path="env:/system/properties/EOL" value="\n" />. [RP]

[Fix] The config file bind element worked only for env bindings, now also works for mem bindings. Fixes bug nr: NLNT138. [RP]

[Fix] The uri in the to and from statements accepts now full blown expressions. Fixes bug nr: NLNT127. [RP]

[Fix] The rigth side of typeof now accepts full blown expressions. Fixes bug nr: NLNT93. [RP]

[Add] Basic Documentation for every concept Developed. [SB]

[Add] Equals added system wide with special implementations for Element Attribute, Series. Now two Elements/Attributes/Series/Concepts can be compared to test equality. [AA]

[Fix] Negative numbers finally working. Fixes bug nr: NLNT137. [RP]

[Fix] The parser parses each concept from a mn8 script file in order. If one concept uses another one which is defined bellow the current one it gets in an endless loop. Make the parser also work with filters so only specified concepts will be loaded.

Now is also possible to specify at the command prompt which subconcept is wanted ex: mn8 XConcept:XSubConcept. As a note in case a script file is given instead of a concept then the first concept in the script will be executed

Fixes bug nr: NLNT75. [RP]

[Fix] mn8 now works well with JDK 1.4 (runs and compiles). Tested under Windows. [RP]

[Update] Updated unit tests to use the new JUnit assert style for compatibility with JDK 1.4. [AA]

[Update] Many small updates to concepts. [RP]

[Fix] Many small bug fixes. [RP]

[Add] Integrated the ReferenceBuilder in the build process. Now every time a new distribution is made, the whole mn8 reference is generated. [RP]

[Add] mn8 Reference is now available mn8 DocReference --f conceptName to generate the documentation template for a concept, mn8 ReferenceBuilder ref_dir to generate the whole mn8 reference in the specified directory. [RP]

[Fix] In the case of more imbricated each on the same source the inner eache's don't work. Fixes bug nr: NLNT124. [RP]

[Update] Under regular mn8 invocation if the script file it is not found now it also checks if it is a concept with the given name in the concept path. If it is available it will be executed. With this direct concept invocation like: mn8 DocReference becomes possible from any directory of the system. [RP]

[Update] mn8 -c Works again, now with the possibility to use regular streams, like: cat /tmp/x.mn8 | mn8 -c. Also improved interpreter which now can detect if it is a regular script or it is a concept. [RP]

[Update] New constructors for Element and Attribute. [RP]

[Fix] Type checking for forced types is case sensitive therefore a variable forced to Element will raise exceptions sometimes. Fixes bug nr: NLNT123. [RP]

[Fix] The sorting code in each/find doesn't work well for depths more than two. There are also some Java exception (index out of bounds) from time to time. Fixes bug nr: NLNT122. [RP]

[Add] Implemented the DocReference concept to generate template reference/man documentation templates for concepts or scripts. [RP]

[Fix] The getName on method is incorrectly defined. Fixes bug nr: NLNT121. [RP]

[Fix] At value addition to a multi element, if the multi element override the default concept label this was not taken into consideration. Fixes bug nr: NLNT120. [RP]

[Fix] getConceptOperators.toXML the attributes are not normalized. Fixes bug nr: NLNT119. [RP]

[Update] Implemented toXML on the FieldConcept. [RP]

[Add] Implemented the Style concept. [RP]

[Fix] Missing concept labels for Character, String, Real. Fixes bug nr: NLNT102. [RP]

[Fix] Missing end of line in script files gives errors. Fixes bug nr: NLNT103. [RP]

[Add] Implemented fromXML:String and loadContent:Concept on concepts. It really needs some serious testing do :) . [RP]

[Add] Implemented contains:String on String concept. [RP]

[Add] Implemented toXML: on Logical, was forgotten. [RP]

[Add] Implemented String + any concept operation. [RP]

[Fix] Element order inversion in concepts. Fixes bug nr: NLNT116. [RP]

[Add] Implemented the ? operator at elements/attributes definition and system wide showEmpty to denote elements/attributed which should not be rendered if content empty. [RP]

[Add] Implemented the ! operator at elements/attributes definition and system wide isHidden to allow hidden elements and attributes in concepts. [RP]

[Add] Implemented TypedSeries. It replaces the Series usage in elements. [RP]

[Update] Implemented the +=,-=,*=,/= operations. [RP]

[Add] Added new Zip concept to allow Zip and Jar files handling. [SC]

[Fix] The clear: method in MapConcept doesn't update the Map length to 0. Fixes bug nr: NLNT111. [SB]

[Fix] Improper handling of dynamically created elements with one element as child. Fixes bug nr: NLNT106. [RP]

[Fix] In the mn8 parser the check for an attribute field was made on the concept definition instead of the concept instance not allowing that way method overloading to work properly when related to attributes. Fixes bug nr: NLNT105. [RP]

[Add] Full mn8 script based mn8Unit implemented, similar to JUnit, allowing that way the testing of mn8 scripts and concepts through test cases and test suites. [AA]

[Add] New Flex concept, which is a flexible concept allowing dynamic element and attributes addition during run-time. [RP]

[Fix] Null pointer exception durring Attribute concept creation. Fixes bug nr: NLNT98. [RP]

[Fix] At each, find first and find last the navigator concept gets a reference to the current element in the data source and not a copy of the value. Fixes bug nr: NLNT94. [RP]

[Fix] Null pointer exception during assignments related to this keyword and a forced type variable. Fixes bug nr: NLNT92. [RP]

[Fix] During parameter downcasting at method invocation only the current inherited concepts are taken in consideration not all the inherited concepts as it should. Fixes bug nr: NLNT89. [RP]
