Changes between Initial Version and Version 1 of Ticket #60355, comment 1

initial	v1
1	1	This sounds like PHP limitation, maybe check https://www.php.net/manual/en/language.oop5.serialization.php.
2	2
3		Think this is a documentation problem in WP. Imho the docblocks for adding options and meta should state clearly that saving ~~instances of~~ PHP objects to the DB is not recommended and that only simple objects are supported (like plain name->value pairs?). Also that the preferable format to save to the DB are strings or associative arrays, not objects.
