	   - Enabled support for JP vertical rendering and multiple writing modes.  Values can be specified in OPF files using meta tags (ex: <meta name=”primary-writing-mode” content=”vertical-rl” />).  The valid values are horizontal-lr, vertical-lr, horizontal-rl, vertical-rl.
	   - Enabled support for facing pages and double page spreads. Values can be specified in OPF through “properties” attribute in itemref tag. The valid values are facing-page-left, facing-page-right, page-spread-left, page-spread-right.
	   - Added Mobi7 support for HTML tags with multiple classes (e.g., class="class1 class2 class3")
	   - KindleGen errors out when original resolution metadata is not specified in the format "integer x integer" for fixed format books.
	   - Validates ordinals used in the region magnification JSON are unique for fixed format books.

Kindlegen version 2.5 build 0626-3a91e28

	   - Improved transparent PNG conversion: Transparent PNG images (now converted to JPEG) will use white background. This originally used black background during conversion causing degraded reading experience.
	   - Unintended line breaks in Mobi7 when using some CSS properties (“margin-top: 0px” and “margin-bottom: 0px”) has been fixed.
	   - Resolved indentation issues in Mobi7 related to bullets and numbered lists. This was due to usage of "margin-left" CSS property with bullets and numbered lists. In Mobi7, the margin-left property is being ignored for bullets and numbered lists. The margin-left CSS property will continue to be preserved in KF8.
	   - Fixed issues related to creating Mobi7 books with indexes (eg. Dictionaries) 
	   - CSS property “display: none” no longer induces an additional space in Mobi7 for inline tags.
	   - Embedded fonts of type PostScript/Type1 does not render well across all Kindle readers with KF8 support. Kindlegen warns about the usage of these fonts in content.  Kindlegen also defaults the user experience to system fonts in such books (specifically for eInk devices).  
	   - Kindlegen gracefully ignores the EPUB3 navigation document (specified using properties=”nav” in manifest) and does not add them to the reading order of the book by default.
	   - Resolved conversion failure when dc:Language tag in OPF has attributes (ex: id attribute).
	   - Resolved issue in building logical TOC due to empty text tags or self-closing text tags in NCX file.
	   - Resolved issue in removing CSS properties that are not supported by Kindle (ex: line-height in px/pt units). Kindlegen removed the trailing “}” in a specific edge case when this was the last property and does not have a trailing semicolon. The issue is fixed in Kindlegen 2.5.
	   - Updated “–releasenotes” option in Kindlegen to point the users to detailed release notes hosted on the web at https://kindlegen.s3.amazonaws.com/manual.html.
