Theme for the Release

This release provides significant updates to the EPUB transform with full support for font embedding and obfuscation. This functionality includes some enhancements to the more general map-to-graphic-map processing to make it easier to extend for things other than just graphics.

This release also has the start of support for the 2.x Open Toolkit. The EPUB transform should work with both versions 1.8.5 and 2.x, although it has not been tested extensively with 2.x versions later than 2.1 at this time. The 2.x version of the preprocessing does not include the adjust copy-to processing provided in the 1.8.5 version but the 2.x OT includes new functionality to ensure that multiple references to the same topic result in uniquely-named HTML files. This new functionality should be sufficient to satisfy the EPUB requirement that a given HTML file only be used once from the EPUB navigation structure. However, it does not, as far as I know, use @keys values to set the result filename so there may be a difference in how result anchors are generated between the 1.8.5 and 2.x versions in this release.

This release also includes a number of accumulated bug fixes and enhancements in various DITA for Publishers and DITA Community plugins.

Resolved Issues

These are the most significant issues addressed in this release:

• EPUB issue #57: Items for audio and video files do not produce correct MIME types.

  Video and audio embedding should now work correctly using the DITA Community <audio> and <video> markup.

• EPUB issue #57: Is `application/svg` the correct media-type for SVG images?

  Embeded SVGs should reflect the correct MIME type.
