Grafana 家的軟體宣佈從本來的 Apache License 2.0 轉換成 AGPLv3：「Grafana, Loki, and Tempo will be relicensed to AGPLv3」。
相關的討論可以在 Hacker News 上的「Grafana, Loki, and Tempo will be relicensed to AGPLv3 (grafana.com)」看到。
Going forward, we will be relicensing our core open source projects (Grafana, Grafana Loki, and Grafana Tempo) from the Apache License 2.0 to the Affero General Public License (AGPL) v3. Plugins, agents, and certain libraries will remain Apache-licensed. You can find information in GitHub about what is being relicensed for Grafana, Loki, and Tempo.
這應該是對 Amazon Managed Service for Grafana 的反擊。
看起來 Grafana 7.5.3、Grafana Loki 2.2.1 以及 Grafana Tempo 0.6.0 是最後使用 Apache License 2.0 授權的版本，不確定會不會有人 fork...
