NFKC_Casefold normalization; available when linked with ICU ≥ 56.
A new flag has been added,
JSON_THROW_ON_ERROR, which can be used
with json_decode or json_encode and causes these functions to throw
the new JsonException upon an error,
instead of setting the global error state that is retrieved with json_last_error and json_last_error_msg.
JSON_PARTIAL_OUTPUT_ON_ERROR takes precedence over
The configuration option --with-libmbfl is no longer available.
Support for ODBCRouter and Birdstep including the birdstep.max_links ini directive has been removed.
