## 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.
- Adds `ToCSharpString()` to output the compile-able C# code described by expression (tries hard).
- Adds `ToExpressionString()` to output the valid expression construction syntax, so given an expression object you'll get e.g. `Expression.Lambda(Expression.New(...))`.

### **FastExpressionCompiler.LightExpression**

- Fixes the compatibility (the drop-in replacement) between `FastExpressionCompiler.LightExpression.Expression` and `System.Linq.Expression`.
- Decreasing the mempry consumed by the created expressions, plus implementing the `IArgumentProvider` and `IParameterProvider` for some of the expressions.
- Now includes the `ExpressionVisitor`.
