     JS APIs have been installed: fossil.fetch, fossil.dom,
     fossil.tabs, fossil.storage, fossil.confirmer.

     Custom events which can be listened for via
     fossil.page.addEventListener():

     - Event 'wiki-page-loaded': passes on information when it
     loads a wiki (whether from the network or its internal local-edit
     cache), in the form of an "winfo" object:

     {
       name: string,
       mimetype: mimetype string,
       type: "normal" | "tag" | "checkin" | "branch" | "sandbox",
       version: UUID string or null for a sandbox page or new page,
       parent: parent UUID string or null if no parent,
       content: string
     }

     The internal docs and code frequently use the term "winfo", and such
     references refer to an object with that form.

     The fossil.page.wikiContent() method gets or sets the current
     file content for the page.

     - Event 'wiki-saved': is fired when a commit completes,
     passing on the same info as fileedit-file-loaded.

     - Event 'wiki-content-replaced': when the editor's content is
     replaced, as opposed to it being edited via user
     interaction. This normally happens via selecting a file to
     load. The event detail is the fossil.page object, not the current
     file content.

     - Event 'wiki-preview-updated': when the preview is refreshed
     from the server, this event passes on information about the preview
     change in the form of an object:

     {
     element: the DOM element which contains the content preview.
     mimetype: the page's mimetype.
     }

     Here's an example which can be used with the highlightjs code
     highlighter to update the highlighting when the preview is
     refreshed in "wiki" mode (which includes fossil-native wiki and
     markdown):

     fossil.page.addEventListener(
       'wiki-preview-updated',
       (ev)=>{
         if(ev.detail.mimetype!=='text/plain'){
           ev.detail.element.querySelectorAll(
             'code[class^=language-]'
           ).forEach((e)=>hljs.highlightBlock(e));
         }
       }
     );
  */

    /* Symbolic markers to denote certain edit state. Note that

      isNew: '[+]',
      isModified: '[*]'

  /**
     $stash is an internal-use-only object for managing "stashed"
     local edits, to help avoid that users accidentally lose content
     by switching tabs or following links or some such. The basic
     theory of operation is...

     All "stashed" state is stored using fossil.storage.

     - When the current wiki content is modified by the user, the
       current state of the page is stashed.

     - When saving, the stashed entry for the previous version is
       removed from the stash.

     - When "loading", we use any stashed state for the given
       checkin/file combination. When forcing a re-load of content,
       any stashed entry for that combination is removed from the
       stash.

     - Every time P.stashContentChange() updates the stash, it is
       pruned to $stash.prune.defaultMaxCount most-recently-updated
       entries.

     - This API often refers to "winfo objects." Those are objects
       with a minimum of {page,mimetype} properties (which must be
       valid), and the page name is used as basis for the stash keys
       for any given page.

     The structure of the stash is a bit convoluted for efficiency's
     sake: we store a map of file info (winfo) objects separately from
     those files' contents because otherwise we would be required to
     JSONize/de-JSONize the file content when stashing/restoring it,
     and that would be horribly inefficient (meaning "battery-consuming"
     on mobile devices).

     the 2.11 release.
  *  Update the built-in SQLite so that the
     "[/help?cmd=sql|fossil sql]" command supports new output
     modes ".mode box" and ".mode json".
  *  Add the "<tt>obscure()</tt>" SQL function to the 
     "[/help?cmd=sql|fossil sql]" command.
  *  [./delta_format.wiki|Delta compression] is now applied to forum edits.
  *  The [/help?cmd=/wikiedit|wiki editor] has been modernized and is
     now Ajax-based. The WYSIWYG editing option for Fossil-format wiki
     pages was removed. (Please let us know, via the site's Support menu,
     if that removal unduly impacts you.) This also changes the semantics
     of the wiki "Sandbox": that pseudo-page may be freely edited but
     no longer saved via the UI.
  *  Countless documentation enhancements.

<a name='v2_11'></a>
<h2>Changes for Version 2.11 (2020-05-25)</h2>

  *  Support [/md_rules|Markdown] in the default ticket configuration.
  *  Timestamp strings in [./checkin_names.wiki|object names]
