Grafana Loki 2021: Year in review

29 Dec 2021 3 min read

This year, we were excited to deliver the easiest version of Grafana Loki to use yet. With Loki 2.4, the Loki team introduced a simple, scalable deployment, and over the past 12 months, we added lots of great new features. Not to mention, we launched Grafana Enterprise Logs, a new addition to the Grafana Enterprise Stack that’s powered by Loki. 

But none of this would have been possible without our active community: In 2021, Loki had 166 contributors and 823 PRs in GItHub. 

Be sure to check out the full release notes and the upgrade guide to get all the latest info about Loki 2.4. Plus check out the blog posts, webinars, demos, and community stories all about Grafana Loki in 2021.
