**New this release:**
- :tada: ([smithy-rs#4418](https://github.com/smithy-lang/smithy-rs/issues/4418), @AmitKulkarni23) Add `expect_number_as_string_or_null` function to `aws-smithy-json` that extracts JSON numbers as strings without converting to u64/i64/f64. This preserves arbitrary precision for BigInteger and BigDecimal support, preventing precision loss for numbers larger than standard numeric types can represent.
