    💥 Breaking changes

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

    • 📜 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.

    ✨ 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.
