0.4.x

Branch started to collect the next set of breaking changes

* 1209e11392521675889e417a5de2bd86540570ec and dd98775b88b88534cfe95dabe0060c0752bdfbd1 complete the separation of the database page storage options.

Not sure if these changes should join with the removal of bouncy ( 36c9f949e3d95488216faf181104df031078da5c ) which is also a breaking changed.
