4.0.2 is a quick update to sneak in some important bugfixes in anticipation of the next monthly release.
The most visible change in 4.0.2 is the long-awaited upgrade of levelup and leveldown to 1.x (#3873), which contains some big improvements to how leveldown is installed. With 4.0.2, instead of needing to recompile leveldown every time PouchDB is npm installed, it will simply be downloaded thanks to leveldown-prebuilt. So if you've ever groaned at the dreaded node-gyp rebuild console message, hop onto 4.0.2 and enjoy the faster install times!
Also noteworthy is that the in-memory adapter is now fully tested and working in IE 10+, thanks to fixes in #4216.
Another big change is that PouchDB is more stable when replicating during intermittent connectivity, thanks to a new "stateless constructor" in the HTTP adapter (#4146). Instead of kicking off HTTP requests immediately when you call new PouchDB('http://example.com/db'), the new version will wait for the first method call, such as db.info().
