Lots of things!.

First, Ephy's SoC proposal was accepted. That means Bookmark and History Integration is coming if everything goes as expected.

Second, Epiphany's bugzilla product went through a winter clean-up. The result is that lots of useless bugs were closed, others were finally fixed and new components were created to reflect reality.

Third, all this bugs were fixed since last release (2.19.2)

383698 "Finished download should not open target directory if that directory is Desktop"
300826 "javascript files of a document are save with no extension"
324166 "add a print progress window"
336739 "Right click on textarea should provide ""Select all"""
351100 "add keyboard shortcut to delete bookmark/topics"
422114 "URL-completion of ftp-URL only works when specifying ftp:// protocol identifier"
437798 "Show password in PDM should be plural"
441419 """go"" button's behaviour"
444500 "Epiphany misses some SelectAll icons"

And this bugs have been fixed since 2.19:

102528 "Location bar should allow editing autocompleted history URLs"
362591 "Middle Click Behavior is not Uniform"
363848 "Can't select a different bookmark topic by moving the mouse"
368759 "progress bar too big in statusbar"
407419 "Epiphany 64-bit can't find 64-bit plugins"
409075 "Old FSF address"
409291 "Put completion in URL entry"
412033 "Find previous when pressing Shift+Return in search field"
415342 "Should add the default Downloads folder to the filechoosers"
416994 "epiphany trunk fails to build -- ephy-adblock.h not found during compilation"
420829 "Epiphany steals F1 key even if disabled globaly"
421060 "Progress bar should be thicker"
423907 "epiphany-2.18.0 breaks strict-aliasing rules"
431665 "Mark .qtl files as safe to open"
431973 "[patch] Fix some strict aliasing warnings in embed/ephy-embed-dialog.c"

As an executive summary, lots of visual/consistency fixes were made and a little surprise for everyone: the location bar now changes when you select things from the completion popup (read, you press the ↓ key and the url appears on the location bar), this is thanks to Xan's work on the GTK+ and Epiphany parts of this. :D
