# JS/TS SDK notes in 2026.9

> 2026.9 notes for the TypeScript and JavaScript SDK 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 the TypeScript and JavaScript SDK are not on this preview yet. Use the
[current JS/TS SDK documentation](/developers/sdks/typescript/introduction) until those notes land.

<Note>
  JS/TS SDK notes for 2026.9 are planned for when compatibility mode turns off on **1 November
  2026**.
