----------------
* Custom syntax can no longer start with a keyword (even a _reserved_ one), even if it has been disabled. That is to avoid breaking scripts later when the keyword is no longer disabled.
Changes to Error Handling
------------------------
* `EvalAltResult::ErrorAssignmentToUnknownLHS` is moved to `ParseError::AssignmentToInvalidLHS`. `ParseError::AssignmentToCopy` is removed.
* `EvalAltResult::ErrorDataTooLarge` is simplified.
* `Engine::on_progress` closure signature now returns `Option<Dynamic>` with the termination value passed on to `EvalAltResult::ErrorTerminated`.
@@ -30,11 +34,13 @@ New features
* `f32_float` feature to set `FLOAT` to `f32`.
* Low-level API for custom syntax allowing more flexibility in designing the syntax.
* `Module::fill_with` to poly-fill a module with another.
* Scripts terminated via `Engine::on_progress` can now pass on a value as a termination token.
Enhancements
------------
* Essential AST structures like `Expr` and `Stmt` are packed into smaller sizes (16 bytes and 32 bytes on 64-bit), stored inline for more cache friendliness, and de-`Box`ed as much as possible.
* `Scope` is optimized for cache friendliness.
