Arrays of Serializable Types Supported by arrayStringConcat

Official CH changelog text
Arrays of all serializable types are now supported by arrayStringConcat. #30840 (Nickita Taranov).
The arrayStringConcat function now supports arrays of all serializable data types.

Why it matters

Previously, arrayStringConcat had limited support for array element types. This enhancement expands its usability by allowing concatenation of arrays containing any serializable data type, making it more flexible and convenient for users dealing with diverse data.

How to use it

Use the arrayStringConcat function on arrays of any serializable type as before. No additional steps are required to enable this feature; just pass your array to arrayStringConcat in your SQL queries.
