What about introducing new hook_mailchimp_lists_merge_vars_alter() to allow other modules make last changes before user is subscribed/updated?
“And now our watch [for support of the 7.x-2.x version of the MailChimp module] has ended…” With the approaching deprecation of MailChimp’s API version 2.0, I’m sad to say we too must turn the page. This branch will become unsupported in early October and officially deprecated by the end of this year (2016).
Fret not! The 7.x-4.x and 8.x versions come highly recommended. Both are using Mailchimp’s new API 3.0 and are being actively maintained. If you find this issue still exists on either the 7.x-4.x or 8.x branches, let us know by opening a new ticket. “What is dead may never die, but rises again, harder and stronger!”
