I think there are two issues in currrent master that should be fixed before the next stable release. The first one is to implement page breaks in the ePub reader (bug #695939). The second issue is to show top link destinations in PDF documents (bug #696442). I’m afraid this is a real bug. There are other issues that I’d love to be included in the next release, but I think these two ones have to be fixed. Many thanks for your excellent work.
Both features require significant work or risk of breakage, and are not suitable for squeezing in at the last moment.
