Based on the knowledge sources provided, I can answer when Iceberg started working in Airbyte. According to the [July 2023 release notes](
https://docs.airbyte.com/release_notes/july_2023), the Iceberg destination was upgraded in version 0.50.6 to 0.50.11. Specifically, the release notes mention: "Additionally, our commitment to keeping our tools updated is reflected in the upgrade of the [Iceberg destination](
https://github.com/airbytehq/airbyte/pull/23201)." However, this implies that Iceberg was already working in Airbyte before this version, and this was just an upgrade. For the initial release of Iceberg in Airbyte, we can look at the [Iceberg Destination Changelog](
https://docs.airbyte.com/integrations/destinations/iceberg#changelog). The earliest version mentioned is 0.1.0, with the comment "Initial Commit" dated 2022-11-01. Therefore, Iceberg started working in Airbyte with version 0.1.0, released on November 1, 2022.
