Release 2027 (pre-release July 2026, final expected September 2026) is the biggest change since the first publication. What does it mean per role?
PUO
New schema version 001.05 and draft 2020-12 in all messages; switchfrom/switchto in message 5; receive and process message 15; phase out messages 7 and 9.
Investment administrator and custodian
Message 10 without cohort-pool layer, message 13 with simplified NAV, send message 15, phase out messages 8 and 12; take over the discontinued ACB role where applicable.
Fiduciary
Message 11 disappears: organise rebalancing and tolerance monitoring outside the standard; receive messages 10 and 14 in the new form.
Our advice
Plan the migration per link, temporarily support two afdDefinitionVersions and use this knowledge base's diff pages per message.
