Prometheus 3.0.0 Beta was announced during PromCon EU 2024 last week. While it’s not ready for production users, you can already see the features it brings. They include:

- A brand new UI enabled by default. It has a modern look & feel based on Mantine UI with light and dark modes, a face-lifted menu structure, a metrics and labels explorer, a PromLens-style query tree view, and a query explanation tab.
- Remote Write 2.0 (we covered it before in this digest).
- OpenTelemetry support with UTF-8 characters for metric and label names and the ability to serve as a native receiver for the OTLP Metrics protocol.
- Native histograms, which are a higher efficiency and lower cost alternative to classic histograms.
- Agent mode is declared stable.
