wpmu_new_blog hook has been deprecated. Use wp_initialize_site instead.

[asaquzzaman]

Please use this hook wp_initialize_site instead of wp_insert_site on deprecated message. Because if we use wp_insert_site hook, we couldn’t access wp_options table for newly created sites eg: updating option table data with update_options with error message:
WordPress database error Table 'ex.wp_10_options' doesn't exist for query SELECT autoload FROM wp_10_options WHERE option_name = 'ex_version' made by wpmu_create_blog, wp_insert_site, do_action('wp_insert_site')

I've been cleaning up old plugins of wpmu_new_blog, and came here to make this exact request. Suggesting wp_insert_site is NOT a good replacement. The suggestion should absolutely be wp_initialize_site instead! (or at least mention both and let people see which makes sense for their specific case)

In 52816:

Networks and Sites: Suggest wp_initialize_site as an alternative for the deprecated wpmu_new_blog action.

The previously suggested alternative, wp_insert_site, does not get passed enough arguments and runs before the new site initialization routine is actually executed.

Props asaquzzaman, henry.wright, MadtownLems.
