Official CH changelog text

Introduces a new setting input_format_json_read_objects_as_strings that enables parsing of nested JSON objects as Strings across all JSON input formats.

Why it matters

This feature addresses the need to treat nested JSON objects as raw strings during input parsing, which can simplify ingestion and handling of complex JSON structures without full deserialization.

How to use it

To use this feature, enable the setting by setting input_format_json_read_objects_as_strings = 1 when processing JSON input data. By default, it is disabled.
