When a long conversation is compacted, older messages are replaced by a summary to save space.\n\nThe description of the transcript request now says that for a compacted session, the service returns only the messages its last compaction kept. Messages that the compaction summarized may not appear on any page.\n\n**Why**\n\nAnything that reads a cloud session's transcript page by page should not assume it has the whole conversation once it reaches the last page.\n\n- Area: Cloud Sessions\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: yes"}
