 - We added a cleanup activity that identifies a URL or a last-visited-date in the `note` field and moves it to the `url` and `urldate` field respectively. [koppor#216](https://github.com/koppor/jabref/issues/216)
 - We enabled the user to change the name of a field in a custom entry type by double-clicking on it. [#9840](https://github.com/JabRef/jabref/issues/9840)
 - We integrated two mail actions ("As Email" and "To Kindle") under a new "Send" option in the right-click & Tools menus.
