v2.1.0 focuses on upgrading dependencies and project infrastructure, as well as replacing end-of-life components. The most notable breaking changes: Loki4j now requires Java 17 or later (previously Java 11), and Logback has been upgraded to 1.6.x. Please check the Migration guide before upgrading.
Loki4j now accepts sponsorships. If your company runs it in production and wants it to stay well maintained (or you simply find it useful), you can support the project on the Support Us page.
