     ## Changelog
     
-    ### 2.0
-
-    * POST `/spot` now supports upstream submission to the spotting services associated with various SIGs.
-    * **Breaking change:** The "add spot" API has changed to enable this: instead of just posting the spot object itself as the JSON content of the POST, this has moved into a `spot` object within the structure. A new `handling` object alongside it contains the `submit_upstream`, `upstream_provider`, `upstream_credentials`, and `captcha_token` fields which control the server handling of the spot.
-    * POST `/spot` now supports Google reCaptcha and (if the site owner has set it up) now requires `captcha_token` in order to successfully submit. (This is used to lock down the submit function and prevent submission via Spothole by bots or third-party clients.)
-    * GET `/options` now returns `spot_submit_providers`, a map of SIG names to the names of providers that support upstream spot submission for that SIG. (This allows clients to present the user with options of where a new spot can be sent to.)
-    * **Breaking change:** A user's QRZ.com and HamQTH credentials are now supplied as request headers (`X-QRZ-Username`, `X-QRZ-Password`, `X-QRZ-Session-Key`, `X-HamQTH-Username`, `X-HamQTH-Password`, `X-HamQTH-Session-ID`) rather than query parameters, to keep credentials out of server logs.
-
     ### 1.4
     
     * Spots can now include a "propagation_mode" field, and the `/options` call enumerates the options that can have.
