1. Generally you rebuild to the latest available versions of yor specified release. APT sorts version deps as it does package deps, so you don't have to.

2. You can reference content under /usr/share/doc/ without having to specify a goddamned version number that a) changes arbitrarily and b) is inconsistently specified every fucking time.

Version numbers are metadata, not directory name elements.

Changelogs, also required, give you the info if you desperately neeed it.
