We're still using YAML to serialize the legislation_annotations ranges
column. I'm not sure whether changing the serializer can have
consequences on existing data, and I'm not sure which serializer we
should provide instead. Quoting the Rails configuration guide [1]:
> Unfortunately there isn't really any suitable defaults available in
> Ruby's standard library. JSON could work as a format, but the json

I think this doesn't affect us because we use RSpec instead of Rails
test classes. In any case, if it ever affects us, we'll get notified
when a test fails.
As mentioned in the pull request introducing this change [1]:
> FATAL is documented in the Ruby Logger docs as being for "An
> unhandleable error that results in a program crash.", which does not
> really apply to this case since DebugExceptions is handling the error.
So we're using the new default value, which makes more sense.

Since we use a version of Loofah supporting HTML5 since db2d0bb80, the
`Rails::HTML::Sanitizer.best_supported_vendor` method will return the
HTML5 sanitizer. As mentioned in the pull request introducting this
change [1], the libxml2 maintainer wrote:
> it's still a bad idea to use a 20+ years old, unmaintained HTML 4
> parser to sanitize input for the modern web
So we're going with the new default sanitizer.
Note we aren't uncommenting the `action_text.sanitizer_vendor` option
because we don't use Action Text and so it doesn't affect us , and
uncommeting it will raise an error.
Also note we need to change one test because the new sanitizer handles
whitespace slightly differently.

We were using an <a> tag wrapping the whole content of the banner in
order to make the whole banner clickable. However, that made the text of
the link less concise, affecting people using screen readers. So,
instead, we're using the `card` mixin, which we introduced in commit
f285dfcba.
We're making this change now because the HTML5 Sanitizer that we're
about to enable in the next commit was handling the whitespace inside
the banner differently, causing one test to fail, and we didn't find a
different way to fix it.
Just like we mentioned in commit 001eee3d6, according to the Rails
configuration guide [1], with this format, Rails serializes cache
entries more efficiently. Most importantly:
> All formats are backward and forward compatible, meaning cache entries
> written in one format can be read when using another format. This
> behavior makes it easy to migrate between formats without invalidating
> the entire cache.

It doesn't really affect us because we never use `return`, `break` or
`throw` inside transactions, since it would be confusing exactly because
it wouldn't be 100% clear whether the transaction is committed or not.
So we're using the new default value, which will be the only available
option in Rails 7.2 [1].

This change doesn't affect us, since we don't use `after_commit`
callbacks, and, among our dependencies, AFAIK only the Devise gem uses
them, and it only defines one after_commit callback when creating a
record and another one when updating it, so we're never going to have
more than one callback being executed after a transaction is finished.
This doesn't really affect us because we don't use `before_committed`
callbacks (and neither do any of our dependencies), so we're using the
new default value.
This is done for performance reasons. Quoting the pull request
introducing this option [1]:
> A config might be overkill, but I wanted to provide an escape hatch
> for any upgraded apps that might be testing the exact value of the
> action_dispatch.parameter_filter header.
Since we don't test the exact value of action_dispatch.parameter_filter,
we can enable this option.

Before this change, every time we saved a record, the association was
validated if we had `belongs_to :something, required: true`. After this
change [1], it's only validated if the `something_id` column is nil (or
`something_type` for polymorphic associations) or if the `something_id`
attribute has changed.
The main difference is that we no longer get validation errors if the
associated record has been deleted. Doesn't affect us much, so we're
going with the new default value.

This is the new default option, and its only dangerous when deploying to
applications with multiple servers. Since this isn't our case, we can
enable it.
The new serializer can decrypt legacy messages using the `marshal`
serializer, so there's no risk of losing data when upgrading. Since we
aren't using applications with several servers, where upgrading some
servers might cause issues on the servers that aren't upgraded yet,
we're enabling the option.

It doesn't really affect us (unless some of our dependencies make this
mistake) because we only use `expires_in/expires_at` once and we do it
correctly, but it might be help us detect this issue if we ever
introduce it in the future.
This option won't even exist in Rails 7.2 [1], and the possibility to
disable it was only added to guarantee safe upgrades in Rails
applications with multiple replicas [2].
Since we don't have applications with multiple replicas, where one
replica could be using Active Job 7.0 and another one could be using
Active Job 7.1 while upgrading, we can enable this options.

The only change between these headers and the ones sent by Rails 7.0
application is that the `"X-Download-Options" => "noopen"` is no longer
sent. Only Internet Explorer used that header, and uploading, previewing
and downloading attachments still works fine on Internet Explorer 11
after this change.
