This is the first Release Candidate of Prometheus 3.0.0. Please test it out on non-critical environments; nothing further will be changed in 3.0.0 except to fix bugs.

Prometheus 3.0.0 includes new features such as a brand new UI and UTF-8 support enabled by default.

New changes since v3.0.0-beta.1:

  • [CHANGE] Disallow configuring AM with the v1 api. #13883
  • [ENHANCEMENT] Scraping, rules: handle targets reappearing, or rules moving group, when out-of-order is enabled. #14710
