SeaMonkey 2.53.10 contains (among other changes) the following major changes
relative to SeaMonkey 2.49.5:

  * The Bookmarks Manager has switched its name to Library, and now also
    includes the History list. When History is invoked, the Library will be
    shown with the History list selected. The extensive modifications were
    needed because of Mozilla Gecko platform API changes.
  * Download Manager has been migrated to a new API. Although it looks pretty
    much the same as before, the search option is missing and some other minor
    details work differently. The previous downloads history is removed during
    the upgrade.
  * The layout panel was added to the CSS Grid tools.
  * TLS 1.3 is the default SSL version now.
  * Support for all NPAPI plugins like Flash, Java and Silverlight has been
    removed. For displaying pdf files in the browser you can use
    pdf.js-seamonkey from Isaac Schemm.
  * SeaMonkey now uses a new api for formatting regional data like time and
    date. Default is to use the application locale of the current SeaMonkey
    build. If you use a language pack or a different OS formatting this is
    usually not desired. You can change the formatting from the application
    locale to the regional settings locale (OS) in the preferences dialog under
    "Appearance".

SeaMonkey 2.53.10 uses the same backend as Firefox and contains the relevant
Firefox 60.8 security fixes.
