Summary of Improvements
This patch release changes the way new frames are generated to inherit settings differently. These changes should qualify as "fixes", but could affect workarounds for anybody that had trouble before. Loading the BiDi package (which happens by default) now changes the default typesetter in addition to the current one. This affects some features such as the commands to typeset into a different frame than the current one when RTL languages are involved. Additionally, the way frames are created has changed so that direction settings such RTL set on the class are inherited by default to default and new frames unless otherwise specified. This affects folio, footnote, and other default frames as well as any created programmatically.
Both changes are likely the behavior most users would expect anyway –hence the minor patch release– but could cause unexpected results in documents that had other ways of dealing with the previous unexpected behavior.
