+## 1.3.0
+- Parser implemented using ANTLR in files MathJSLabLexer.g4 and MathJSLabParser.g4. The wrapper class for lexer and parser has been created in file Parser.ts. Need to make extensive tests.
+- File names converted to camel case.
+- The file AST.ts (Abstract Syntax Tree) has been created, and related types and interfaces defined in Evaluator.ts has been moved to AST.ts file.

 ## 1.2.5
-- Optimizations (resulting return as number) and code cleaning by hand in file 'parser.jison'.
+- Optimizations (resulting return as number) in multi-array.ts file and code cleaning by hand in file 'parser.jison'.

 * String type and their respective functions.
-* Parser is designed to scan a line (now support spaces and newlines
-inside block comments and arrays). Need to code a parser that scan
-multiple lines calling Evaluator when need.
-The real need is a parser that supports both modes: single-line and
-multi-line.
 * More extensive tests need to be written, especially to test the parser and
 evaluator.
-* Search for other compiler-compiler tools besides
-[Jison](https://gerhobbelt.github.io/jison/), for use in the project.
-[Jison](https://gerhobbelt.github.io/jison/) has many limitations and the
-generated parser is not suitable for compiling together with
-[ES6](https://262.ecma-international.org/6.0/) modules written in
-[Typescript](https://www.typescriptlang.org/). This is the reason why
-MathJSLab is compiled as an ES5 module. At now we are developing a parser
-using ANTLR4 and version 1.2.5 is probably the last version of MathJSLab
-using Jison.
