Previous versions had individual spam and approve buttons for a comment
in the admin area on the GridField row. However with the upgrade to
SilverStripe 4, and particularly 4.2, these were having layout issues
with the new GridField Action Menu component that groups actions
together.
The solution here is to put them into aforementioned gridfield action
menu component, with the other actions for that row. However this
requires two separate grid field components (one each for the two
comment actions) - previously these were a single component that output
two buttons instead of one each. This also reduces coupling, which is
nice :)
The previous class is still maintained for backwards compatibilty, but
is deprecated.
