(#2302) - Update jekyll config version
(#2302) - Bump version for release :)
(#2313) - Remove opts.server option for replication

(#2331) - forgot to commit version-browser.js
(#2332) - fix dev server callback error
(#2283) - 'destroyed' event has correct db name

2. databases with the same names but different backends collided
