 ==========
 
+2.3.7
+-----
+## Add
+- Logic for handling setting up a session when a consent screen is encountered.  This is primarily seen in European countries
+  and should allow for the continued use of this package.
+- Keyword argument, `setup_url`, to the base `_YahooFinance` class that allows a user to override the url used in setting up the session.  As a default
+  the Yahoo Finance home page is used (https://finance.yahoo.com).  You can also create an environment variable, `YF_SETUP_URL` that will be used if set.
+  Example usage:
+  ```python
+  import yahooquery as yq
+
+  t = yq.Ticker('aapl', setup_url='https://finance.yahoo.com/quote/AAPL')
+  ```
+
+## Remove
+- Webdriver manager is no longer used internally.  Selenium Manager is now fully included with selenium `4.10.0`, so this package is no longer needed.
