v1.4.0

This version adds support for integer ranges via the .. and ..= operators.
Many standard API's are extended with range parameters where appropriate.

A number of usability improvements simplify integration with Rust.

Script-breaking changes

• is is (pun intended) now a reserved keyword to prepare for possible future type checking expressions (e.g. x is "string").

Breaking changes

• LogicPackage is removed from CorePackage.
• Bit-field functions are moved into a new BitFieldPackage (used to be in LogicPackage) which makes more sense.

Bug fixes

• Custom syntax now works properly inside binary expressions and with method calls.
• Hex numbers with the high-bit set now parse correctly into negative integer numbers.
• Constructing a literal array or object map now checks for size limits for each item instead of at the very end when it is already too late.
• Non-INT integer types are now treated exactly as custom types under only_i64 and only_i32.
• Calling pad on an array now checks for total size over limit after each item added.

New features

• Added support for integer ranges via the .. and ..= operators.
• Added EvalAltResult::ErrorCustomSyntax to catch errors in custom syntax, which should not happen unless an AST is compiled on one Engine but evaluated on another unrelated Engine.

Enhancements

• BLOB's are refined to display in a more compact hex format.
• A new syntax is introduced for def_package! that will replace the old syntax in future versions.
• Added NativeCallContext::call_fn to easily call a function.
• Doc-comments on plugin module functions are extracted into the functions' metadata.

Deprecated API's

• Expression::get_variable_name is deprecated in favor of the new Expression::get_string_value.
• The old syntax of def_package! is deprecated in favor of the new syntax.
