## 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
