From the release notes
HubSpot Updates: May 29, 2026
Friday closed the week with three updates, and all three are about the same thing: making AI useful at the moments where context usually gets lost. Knowledge Vaults learned to read spreadsheets, Customer Agent learned to hand off a ticket like a professional, and attribution reporting gained a memory.
If you watched Monday's show, you already heard the conversation around two of these. If you did not: Watch the recap to hear our thoughts on these updates and more.
Platform Updates Detailed
Structured Knowledge for Knowledge Vaults
Knowledge Vaults now support uploading and querying structured data files, including xlsx, csv, json, and xml, which means agents can answer analytical and aggregation questions directly from tabular data. This is live across all hubs and tiers.
Why it matters: Until now, a spreadsheet in a Knowledge Vault was effectively invisible, blocking exactly the lookups and computed questions that spreadsheets exist to answer. The honest caveat is that uploaded files are static, and a static copy starts aging the moment it lands. The interesting play is pairing this with workflow file outputs so a vault's data file gets refreshed automatically, turning a one-time upload into a living reference. If your agents keep whiffing on pricing tables or product matrices, this is the fix.

Handoff Summaries
When Customer Agent reassigns a ticket to a human, an automated recap now appears instantly as a note on the timeline: a headline naming the core issue, the handoff reason, a conversation recap covering what the customer asked and what the agent already tried, the unresolved issues, and any customer-shared links and files. This is in private beta for Service Hub Professional and Enterprise.
Why it matters: Every minute a rep spends re-reading a transcript is a minute the customer waits, and the unresolved-issues piece is the part that earns its keep, since knowing what was not attempted matters as much as knowing what was. There is also a quiet bar being set here: most human-to-human handoffs do not arrive this structured. The next thing to watch for is customization, summaries that map to your specific escalation process rather than a generic recap, but the foundation has to come first.

Email Performance Attribution Over Time
Attribution snapshot reporting captures your attribution data at regular intervals and displays it as a trend line, starting with revenue attribution on email performance pages. This is in private beta for Marketing Hub Professional and Enterprise.
Why it matters: Attribution reports have always been a single point-in-time photo, which means you could see who gets credit today but never whether last quarter's strategy shift actually moved anything. A trend line turns attribution from a credit assignment exercise into a feedback loop. Email is just the first surface; the snapshot approach is the part worth watching as it spreads.

Key Takeaways and Next Steps
Context transfer is the new feature category: A spreadsheet an agent can query, a handoff a rep can act on, a trend a marketer can learn from. All three updates exist to move context across a boundary where it used to evaporate. The teams that benefit will be the ones whose source material is in order, so the prep work is the same as ever: clean knowledge, clear processes, agreed definitions.
Private betas worth raising your hand for: Handoff Summaries and attribution snapshots are both first releases with obvious expansion paths. If Customer Agent handoffs or attribution trends matter to your operation, enrolling early means your feedback shapes where the customization goes.
