+#### Behavior changed: Directory `databases` in `userData` will be deleted
+
+If you have a directory called `databases` in the directory returned by `app.getPath('userData')`, it will be deleted when Electron 32 is first run. The `databases` directory was used by WebSQL, which was removed in Electron 31. Chromium now performs a cleanup that deletes this directory. See [issue #45396](https://github.com/electron/electron/issues/45396).
