                            Commons JEXL Package
                                Version 2.0
                               Release Notes


INTRODUCTION:
=============

JEXL is an Expression Language supporting most of the constructs in the
JSTL Expression Language, along with some additional extensions.

  http://commons.apache.org/jexl/

Changes in this version include:

Incompatible Changes
====================

Now requires Java 1.5 or later.

The following classes have been deprecated:

  * ExpressionFactory
  * ScriptFactory

  Please create a JexlEngine and use createExpression() or createScript()
  instead.

The following classes have been removed:

  * VelMethod
  * VelPropertyGet
  * VelPropertySet

  Please use JexlMethod, JexlPropertyGet and JexlPropertySet instead.

The following methods have been removed:

  * Info.getTemplateName() - use Info.getName() instead
  * Expression.addPostResolver() / Expression.addPreResolver() - set ant-like variables in JexlContext, implement
    a specific JexlContext or derive JexlcontextInterpreter/JexlEngine instead

Division (/ operator) behavior change:
  * Division between integers no longer casts its operands to double; integer division
    allways results in a integer.

New Features:
=============

Assignment expression: a = b (and a.b.c = d)
   * Assigns a variable (ant-like variable or bean-property)

Ternary operator expression: a ? b : c  (and a ?: c)
   * The usual inline conditional shortcut and its 'Elvis' form (a ?: b evaluates as a ? a : b)

Constructor call expression: new('my.class.name', arguments...)
   * Creates a new instance of a class using the most appropriate constructor according
     to the actual arguments

Function namespace: ns:func(arguments...)
   * A function namespace allows the use of class or instance methods in function calls

UnifiedJEXL
   * Adds ${...} and #{...} JSP/EL syntax support on top of the JexlEngine

JSR-223 support
   * Implement JSR-223 Scripting Engine for JEXL script (need BSF-3.0 on Java < 6)

Error and exception handling
   * Configuring the leniency and verbosity of the Jexl engine allows user control over the
     error handling policy

Bugs fixed:
