 URL parameters can be used to trigger an "embedded" mode which hides the headers, footers and settings. In this mode, you provide configuration for the various filter and display options via additional URL parameters. Any settings that the user has set for Spothole are ignored. This is so that the embedding site can select, for example, their choice of dark mode or SIG filters, which will not impact how Spothole appears when the user accesses it directly. Effectively, it becomes separate to their normal Spothole settings.

 By default, all outdoor programme providers are enabled, as is one cluster node and the NG3K DXpedition data. The RBN spot providers are turned off by default due to the volume of traffic from CW/RTTY/FT8 skimmers, and the APRS and Packet spot providers are off by default on the assumption that Spothole users want a spot with a human at the other end of it, but all can be easily re-enabled.
 
-`config.yml` has some entries for QRZ.com username & password, and Clublog API keys. If provided, these allow Spothole to retrieve more information about DX spots, such as the country their callsign corresponds to. The software will work just fine without them, but you may find a few country flags etc. are less accurate or missing.
+Other parameters you will want to update include the base URL to your instance, and whether you want to serve a full web-based DX cluster interface or just the API endpoints for client software to use.
 
-Clublog API keys are free, but you'll need to get your own by submitting a helpdesk ticket and explaining what you'll use it for.

     <p>Note that the server owner has not necessarily enabled all these data sources. In particular it is common to disable RBN, to avoid the server being swamped with FT8 traffic, and to disable APRS-IS and UK Packet Net so that the server only displays stations where there is likely to be an operator physically present for a QSO.</p>
     <p>Between the various data sources, the following Special Interest Groups (SIGs) are supported: Parks on the Air (POTA), Summits on the Air (SOTA), Worldwide Flora & Fauna (WWFF), Global Mountain Activity (GMA), Worldwide Bunkers on the Air (WWBOTA), HuMPs Excluding Marilyns Award (HEMA), Islands on the Air (IOTA), Mills on the Air (MOTA), the Amateur Radio Lighthouse Socirty (ARLHS), International Lighthouse Lightship Weekend (ILLW), Silos on the Air (SIOTA), World Castles Award (WCA), New Zealand on the Air (ZLOTA), Keith Roget Memorial National Parks Award (KRMNPA), Wainwrights on the Air (WOTA), Beaches on the Air (BOTA), Lagos y Lagunas On the Air (LLOTA), Towers on the Air (WWTOTA), Tiles on the Air, Worked All Britain (WAB), Worked All Ireland (WAI), and Toilets on the Air (TOTA).</p>

     Please note that the data coming out of Spothole is only as good as the data going in. People mis-hear and make typos when spotting callsigns all the time, and there are plenty of areas where Spothole's location data may be inaccurate. If you are doing something where accuracy is important, such as contesting, you should not rely on Spothole's data to fill in any gaps in your log.
     
+    Spothole's source code is located at https://git.ianrenton.com/ian/spothole and the README there provides setup instructions if you would like to run your own copy. A demonstration server of Spothole is located at https://spothole.app.
+    
     ## Changelog
     
+    ### 1.4
+
+    * POST `/spot` now supports upstream submission to external providers such as POTA and SOTA via new `submit_upstream`, `upstream_provider`, and `upstream_credentials` request body fields.
+    * 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.
+
     ### 1.3
     
     * `/solar` response now includes `ionosonde_data`, which contains ionosonde station measurements (LUF, foF2 and MUF) sourced from the GIRO Data Center as well as implied band states.
