Change effective on 05 February 2019
Today, we are excited to announce Redis 4.0 is available in beta on Heroku, bringing a number of performance improvements to our managed Redis database service. The beta provides customers who want to try out the new release an easy way to do so, while customers who are happy with the current version can continue to stay on version 3.2 until we make version 4.0 generally available. Also, new Redis databases will continue to default to version 3.2 until we release version 4.0 to GA.
The Redis project’s release notes for version 4.0 can be found here: https://redislabs.com/blog/redis-4-0-0-released/.
To provision a new Redis database with version 4.0, you can pass the
--version 4 flag, like so:
heroku addons:create heroku-redis --version 4
