Release notes can be found at https://www.seamonkey-project.org/releases/seamonkey2.53.3/
A big warning at the top of the page:
This version makes changes to your profile that can't be reverted in case you want to go back to a previous version of SeaMonkey. You MUST absolutely do a full backup of your profile before trying SeaMonkey 2.53.3.
Automatic upgrades from previous versions are disabled for this release. Please download the full installer from the downloads section and install SeaMonkey 2.53.3 manually over the previous version.
What's New in SeaMonkey 2.53.3
SeaMonkey 2.53.3 contains (among other changes) the following major changes relative to SeaMonkey 2.53.2:
The LaTex tool TexZilla, used for inserting Math, has been upgraded to 1.0.2.
It is now possible to customize the toolbars in Composer and the formatting toolbar in Mailnews composition.
All folders of an account can now be marked as read.
There is now an option for not advertizing SeaMonkey at all in the user agent.
The preference for hiding the toolbar and menubar grippies can now be changed from "Preferences->Appearance".
Change default to not autohide tab bar when there is only one tab in a window.
Update of help page content and links.
SeaMonkey language packs are now version specific and will be disabled as part of the profile upgrade following the installation of a later version.
Search Engines have been centralized and updated in bug 1300198.
Address book now has updated IM fields, improved layout for card view pane, improved multi-word search, ability to search across multiple address books, more granular prompts when deleting items, print on the context menus and print button on the toolbar.
Multimedia support has been updated in preparation of supporting more audio video formats in the next releases. For enhanced security the Rust multimedia parser is now used for this and the libstagefright package has been removed.
SeaMonkey 2.53.3 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 invoking History, 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.
The only NPAPI plugin which will work with SeaMonkey 2.53.3 is Flash. Support for other NPAPI plugins like 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 2.53.3 uses the same backend as Firefox and contains the relevant Firefox 60.3 security fixes.
SeaMonkey 2.53.3 shares most parts of the mail and news code with Thunderbird. Please read the Thunderbird 60.0 release notes for specific changes and security fixes in this release.
Additional important security fixes up to Current Firefox 77 and a few enhancements have been backported. We will continue to enhance SeaMonkey security in subsequent 2.53.x beta and release versions as fast as we are able to.
This contains security fixes from another four Firefox major versions (73-77)
