# Changelog

## IBKR Excel API

All references to the legacy installers in interactivebrokers.github.io/ have been updated to reflect our new install page, [https://download2.interactivebrokers.com/installers/tws-api/index.html](https://download2.interactivebrokers.com/installers/tws-api/index.html)

## IBKR API Changelog

Unique changelog pages have been created for each major section of the IBKR Campus API Documentation.

## IBKR Excel API | Excel ActiveX | Excel DDE | Excel RTD

All Excel API Pages have been updated to reflect the Best Practices information for Trader Workstation.

## Excel DDE

"Operating Without a DDE Socket" section has been removed from documentation. Interactive Brokers no longer supports connecting TWS to the Excel DDE offering without the use of the intermediary Java DDE Socket Bridge. This also means that the LegacyDDE request structure is now deprecated. Customers should review the DDE Socket Bridge section to better understand how to run and operate the DDE Socket Bridge.
