# Change Log

## Unreleased

### Added

 * Add the `ContextMut` trait, that is a manipulable configuration/context
 * Add `ContextNotManipulable` error variant for the `EmptyContext`
 * Make the `TupleType` alias public
 * Add the `ValueType` enum that represents the type of a value for easier comparisons and matchings
 * Add `EvalexprResult<T>` type that uses the `EvalexprError` type (renamed from `Error`)
 * Add `Node::eval_number` and `Node::eval_number_with_context` to evaluate to int or float and silently converting to float
 * Add `eval_number` and `eval_number_with_context` crate methods to evaluate to int or float and silently converting to float

### Removed

### Changed

 * Get rid of some unwraps to improve safety
 * Rename `Error` to `EvalexprError`
 * Rename `Configuration` to `Context`
 * Rename `HashMapConfiguration` to `HashMapContext` and `EmptyConfiguration` to `EmptyContext`
