2017.6

See http://vivliostyle.com/en/documentation/supported-features/ for supported features.

Added

• Implement repeat-on-break property #323
  • Spec proposal: CSS Repeated Headers and Footers
• Support float: snap-block #344
  • Spec: CSS Page Floats - The float property
  • Note that the function value snap-block() is not supported yet.
  • Also note that behavior of this value is different from that defined in the above spec: The element always turns into a page float regardless of its distance from edges of its float reference. It is snapped to the nearer edge of the float reference.
• Support clear: all for block-level boxes #345
  • Note that all is only effective on block-level boxes (i.e. not page floats).
  • When all is specified, the block-start edge of the box gets pushed down so that the edge comes after any block-start/block-end page float of which anchors are before the box in the document order.
• Add support for ::nth-fragment() pseudo-element selector #342
  • Spec: CSS Overflow Module Level 4 - Fragmen styling
• Add support for ::after-if-continues pseudo-element #348
• Support footnote-policy: line #353
  • Spec: CSS Generated Content for Paged Media Module Level 3 - Rendering footnotes and footnote policy

• Disable hyphenation by default #363

Fixed
