Mercury 11.0.0

* Option to provide a download icon in the caption area for images and/or videos. The size of the download icon may also be controlled independently.
* Choosing "Link to originals via scaled images" is now permitted, since the newly-introduced download icon can be tied to the original images (i.e., display the scaled image, but let the visitor download the full-sized original).
* Improved positioning of navigation icons on slide pages.
* Revised handling of slide page layout when "Link to Originals" is chosen.
* Default dimensions for YouTube and Vimeo videos changed.
* Maximum dimensions for YouTube and Vimeo videos increased.
* Some small code improvements.

* Option, when not using fixed-shape thumbnails, to constrain the aspect ratio (width divided by height) of the thumbnails, with a minimum of 0.5 and a maximum of 2.5. This prevents panoramic images and exceptionally tall, skinny images from producing thumbnails with extreme aspect ratios, which tend to distort the thumbnail table layout.
* Completely revised method for handling folders that don't have a representing thumbnail image. This includes the ability, when using the Custom style, to specify the background color behind the generic folder icon; preset styles use a color-matched background.
* Improved handling of thumbnail images that are smaller than the user settings require.
* More selective copying and loading of resource files.
* More selective CSS inclusion.
* More efficient folder thumbnail sizing.
* Method for excluding unsupported objects altered to accommodate processing sequence in latest release of jAlbum.
* Album generation is aborted if you choose non-fixed-shape thumbnails, but also choose thumbnail image bounds that have an aspect ratio (width/height) that is less than 1.0. The justified gallery of thumbnails is fundamentally incompatible with portrait mode image bounds.
* Default for video autoplay set to false.

* Option to choose alternate navigation icons for the "site home" and "album home" links.
* Revised default and upper limit for theme image width.
* More selective generation of navigation icons to output directory.
* User-provided URL's are now automatically encoded, unless they contain the "%" character, in which case it is assumed that they have already been encoded.
* Updated import variable exclusion list.

* Revised navigation options and icons. If a URL and text are entered under "Album > Settings > Pages > Link to homepage," a "site home" icon is shown on each page of the album. If "Link to album home" is selected under "Mercury > Layout > All Pages & Index Page > All Pages," an "album home" icon is shown on each page of the album below the top level, which takes the visitor to the top level of album. As before, an "up" icon is shown on each page of the album below the top level, which takes the visitor to the level immediately above the current level.
* Support for chained directories withdrawn. These were causing unfixable navigation problems on small devices.
* Improved positioning of titles and navigation icons on small displays, including a fix for one bug that would sometimes make a navigation icon inaccessible.
* A fix for a bug with the "top of page" action in Safari.
