When updating an existing taxonomy term that shares its `term_id` with another term, we generate a new row in `wp_terms` and associate the updated term_taxonomy_id with the new term. This separates the terms, such that updating the name of one term does not change the name of any others. In cases where a plugin or theme stores term IDs in the database, term splitting can cause backward compatibility issues. The current changeset introduces two utilities to aid developers with the transition. The `'split_shared_term'` action fires when the split takes place, and should be used to catch changes in term_id. In cases where `'split_shared_term'` cannot be used, the `wp_get_split_term()` function gives developers access to data about terms that have previously been split. Documentation for these functions, with examples, can be found in the Plugin Developer Handbook. WordPress itself stores term IDs in this way in two places; `_wp_check_split_default_terms()` and `_wp_check_split_terms_in_menus()` are hooked to `'split_shared_term'` to perform the necessary cleanup. See [30241] for a previous attempt at the split. It was reverted in [30585] for 4.1.0. Props boonebgorges, mboynes. See #5809.
