# Building integrations notes in 2026.9

> 2026.9 notes for custom connectors and integrations are not on this preview yet.

<Note>
  This is 2026.9 preview documentation. Coverage here is incremental: a page exists only where
  2026.9 differs or is newly documented.
</Note>

2026.9 developer notes for custom connectors and integrations are not on this preview yet. Use
[Building integrations](/developers/building-integrations) until those notes land.

<Note>
  Connector update dates for people who publish and load in a design tool are under [Connectors in
  2026.9](/next/connectors/overview). This page is for people who build connectors.
