.asCallback is not a function

See original GitHub issue

Environment

Knex version: 0.20.11, was not present in 0.20.10 Database + version: mariadb OS: ubuntu16

Bug

(node:1505) UnhandledPromiseRejectionWarning: TypeError: self.knex.select(…).from(…).where(…).andWhereRaw(…).then(…).asCallback is not a function at /home/shodan/shodan/node_modules/connect-session-knex/index.js:264:5 at processTicksAndRejections (internal/process/task_queues.js:93:5)

Seems like bluebird was replaced with native promises somewhere, and asCallback was lost.

I think we should add link to that document near to changelogs to documentation page. I didn’t see any mentions about it there.
