0.2.0 - 2015-09-16

Beta release.

Added

Changed

Fixed

  • [core] Avoid incorrect margin collapse of the page area
  • [core] Fix incorrect positioning of floats

0.1.1 - 2015-05-06

Minor update with several changes and bug fixes.

Added

Changed

  • [core] Cascade page size specified in @page rules to page masters defined by @-epubx-page-master rules
    • #17
    • When @page rules and @-epubx-page-master rules are both specified, the page size specified by 'size' property in @page rules is applied to the selected page master. This behavior is not defined in the related specs. We added this behavior for a use case in which one wants to print content styled with Adaptive Layout on a paper sheet and wants to specify the sheet size by adding a (user) stylesheet containing @page rules with 'size' property.

Fixed

0.1.0 - 2015-04-28

Initial alpha release. Following features are added while keeping the original Adaptive Layout features.

Added

  • [core] Support @page rule
  • [viewer] Support spread view mode
    • #7
    • The spread view can be enabled by adding '&spread=true' to the end of the viewer URL.
    • Note: Page size calculation is incorrect when content with 'auto' page size is viewed in the spread view mode. This problem will be fixed in the next release.
  • [viewer] Added page navigation buttons
