v2.0.0 Developed with a help of @jogibear9988, @dzmitry-lahoda, @MaceWindu, and other contributors - kudos to all of them! - removed: `ExpressionInfo` was moved into separate package `FastExpressionCompiler.LigthExpression` with all the functionality of the FEC. The `ExpressionInfo` itself was renamed to `Expression` for more simple drop-in replacement. - added: #59 Support compiling delegates with ref and out parameters - added: #78 Lambda<Func<int>>(Block(Label(Label(typeof(int)), Constant(7)))) is not supported - added: #88 Lambda<Func<IntPtr>>(Block(Constant(IntPtr.Zero))) - added: #91 Support for MultiplyAssign, AddAsiggn, DivideAssign - added: #98 % and bit operators are not supported - added: #101 Some Assign Modes are not yet supported - added: #102 Label and Goto Expression not yet implemented - added: #105 Bit Expression Types are not yet supported - added: #106 ExpressionType.Power not supported - added: #107 Check if xxxAssigns also work with Variables - added: #118 Support for Expression.Variable (in a Expression.Block) - added: #127 Switch is not supported - added: #130 Net Framework Expression compiler generates perfromanter Code for isNull check - added: #138 Optimize Compilation of nested Lambdas - fixed: #83 Issues with linq2db tests - fixed: #92 Expression not compilable - fixed: #93 Comparison to "null" does not work when not Typed - fixed: #95 Ref support not yet working completely - fixed: #124 LightExpression wrong Type - fixed: #131 Linq2db - Test for JIT compiler internal limitation - fixed: #137 Problem with Reading & Writing of Struct Fields. - fixed: #146 Boolean parameter value changed from false to true - fixed: #147 'Common Language Runtime detected an invalid program' with int.TryParse - fixed: #151 'Attempt to read protected memory' - fixed: #152 int.MinValue access throws 'Method not supported' - fixed: #154 Equals Expression does not call "Equals" of class (in MS Code) - fixed: #156 Invoking an Action constant fails with 'Common Language Runtime detected an invalid program' - fixed: #159 Condition with converted numeric comparisons gives unexpected result - fixed: #162 Float - short numeric comparisons with conversions gives unexpected result - fixed: #163 Add of Nullable Int, etc does not work correctly - fixed: #165 Int and Decimal to Double conversion issues - fixed: #170 Problems with ref parameters - fixed: #172 Using FEC to compile a property setter with an enum value sets the property to random values
