If index lengths change in table definitions, we don't recreate the index - instead, we throw a database error, as `dbDelta()` tries to create a new index with the same name.
It's better to leave the index as is, MySQL doesn't have an efficient process for resizing indices, and dropping/creating is a slow process which we don't want to trigger automatically.

`get_network()` falls back to the current network when called without any arguments. Between this and `get_current_network_id()`, we can replace almost all instances of the global `$current_site` and all instances of `get_current_site()`.
This effectively deprecates `get_current_site()`, something that we'll do in a future ticket.

In [37888], the comment text was initially updated, however an opportunity to make the text less trivializing of actions that users will take was missed. To quote Helen Hou-Sandi: "It's important not to trivialize actions that are perfectly reasonable for a user to find tricky (where to go to log in is not exactly intuitive, even with the rewrites we have now)."
The text of the comment now reads:

`dbDelta()` compares the index definitions against the result of `SHOW INDEX FROM $table_name`. This requires a specific format so indices are not unnecessarily re-created. This format wasn't ensured, until now.
* Parse the raw index definition to extract the type, name and columns so a normalized definition can be built (#20263, #34873).
* Standardize on uppercase types (#34871) and on 'KEY'. 'INDEX' is only a synonym for 'KEY'.
* Escape index names with backticks (#20263).
* Normalize columns: Ignore ASC and DESC definitions (#34959), remove whitespaces (#34869) and escape column names with backticks (#20263).
* Add backticks to all index change queries (#20263).

When upgrading to `utf8mb4`, `TEXT` fields will be upgraded to `MEDIUMTEXT` (and likewise for all other `*TEXT` and `*BLOB` fields). This is to allow for the additional space requirements of `utf8mb4`.
On the subsequent upgrade, after the `utf8mb4` upgrade, `dbDelta()` would try and downgrade the fields to their original size again. At best, this it a waste of time, at worst, this could truncate any data larger than the original size. There's no harm in leaving them at their original size, so let's do that.

Multisite functions use the term "blog" to refer to what we now call a "site," e.g. `get_current_blog_id()`. These functions are here to stay because of our commitment to backwards compatibility. What we can do is set the documentation straight.

Adds a new table to the database schema (`wp_termmeta`), and a set of
`*_term_meta()` API functions. `get_terms()` and `wp_get_object_terms()`
now also support 'meta_query' parameters, with syntax identical to other
uses of `WP_Meta_Query`.
When fetching terms via `get_terms()` or `wp_get_object_terms()`, metadata for
matched terms is preloaded into the cache by default. Disable this behavior
by setting the new `$update_term_meta_cache` paramater to `false`.
To maximize performance, within `WP_Query` loops, the termmeta cache is *not*
primed by default. Instead, we use a lazy-loading technique: metadata for all
terms belonging to posts in the loop is loaded into the cache the first time
that `get_term_meta()` is called within the loop.

It's pretty easy to run over the `option_name` length, which causes undefined behaviour when inserting and retrieving options. Increasing the length from `VARCHAR(64)` to `VARCHAR(191)` significantly reduces the risk of this occurring.
Because `option_name` has a `UNIQUE` index, we can only increase it to 191 characters, rather than 255. The index can only use a prefix of 191 characters, so will incorrectly restrict long different strings that have the same prefix, if we make the column longer.

[32814] introduced a routine to split shared terms, which was run during the
regular WP database upgrade. This turned out to be problematic because plugins
are not loaded during the db upgrade (due to `WP_INSTALLING`), with the result
that plugins were not able to hook into the 'split_shared_term' action during
the bulk split. We work around this limitation by moving the term splitting
routine to a separate process, triggered by a wp-cron hook.
