## v3.0.0 - Major feature release The version contains a lot of fixes and improvements and hopefully as-little-as-possible breaking changes. ### **FastExpressionCompiler** and **FastExpressionCompiler.LightExpression** - Performance and memory consumption is improved, especially for the expressions with the closure and for expressions with the nested lambdas. - Filled the gaps in the expressions support. - Many fixes in the IL emit. ### **FastExpressionCompiler.LightExpression** - Fixes the compatibility (the drop-in replacement) between `FastExpressionCompiler.LightExpression.Expression` and `System.Linq.Expression`. - Minimizing memory consumption by the created expressions. - Now includes the `ExpressionVisitor`. - Adds `ToCSharpString()` to output the C# code described by expression (tries hard). - Adds `ToExpressionString()` to output expression construction in the C# code, so given an expression object you'll get e.g. `Expression.Lambda(Expression.New(...))`. ### The full list of fixes [Milestone v3.0.0](https://github.com/dadhi/FastExpressionCompiler/milestone/19)
