Welcome to Sidekiq 7.0!

Sidekiq 7.0 contains some breaking changes which streamline proper operation of Sidekiq. It completes the transition from the redis gem to the redis-client gem, which adds support for the RESP3 protocol and provides better compatibility with future versions of Redis.

What's New

redis-client

Sidekiq 6.5 introduced beta support for the redis-client gem while defaulting to using the redis gem. Sidekiq 7.0 completes this transition and no longer uses the redis gem internally. Your app can still continue to use redis. If you use Sidekiq.redis to access Redis connections, that API is now exposing a connection based on redis-client.

redis-namespace

Support for redis-namespace has been removed. I have advised against its usage for many years now. One option is to use Redis's numbered databases instead.

Version Support

Redis 6.2+ is now required
Ruby 2.7+ is now required
Rails 6.0+ is now supported

Support is only guaranteed for the current and previous major versions. With the release of Sidekiq 7, Sidekiq 5.x is no longer supported.

Upgrade

As always, please upgrade Sidekiq one major version at a time. If you are already running Sidekiq 6.x, then:

Upgrade to the latest Sidekiq 6.x.

gem 'sidekiq', '< 7'

Fix any deprecation warnings you see.
Upgrade to 7.x.

gem 'sidekiq', '< 8'
