 | 6.8.0 | 2026-06-24 | [80806](https://github.com/airbytehq/airbyte/pull/80806) | Restore 12 Web Analytics streams removed during the v5.8.0 manifest-only migration. Uses HubSpot's latest 2026-03 Events API endpoint with explicit `eventType` fanout. Streams require the `business-intelligence` scope (Marketing Hub Enterprise) plus each parent stream's read scope. Gated behind `enable_experimental_streams` with fresh state from `start_date`. |
 | 6.7.0 | 2026-06-11 | [76396](https://github.com/airbytehq/airbyte/pull/76396) | Add `treat_numbers_and_booleans_as_strings` config toggle to coerce dynamic `number`/`boolean` properties to `string` |

Clarify existing `lookback_window` field as CRM Search-specific. |
