0.1.0 / 2022-10-25

This version marks the initial open-sourcing of PromLens to the Prometheus project by PromLabs. See the PromLabs announcement blog post for more details. Note that we are resetting the versioning scheme from the prior proprietary PromLabs version 1.1.0 back to 0.1.0, as this gives us more flexibility with regards to breaking changes. The rationale for allowing a version reset is that the project now lives under a new namespace and governance, including a new location for its source code and Docker images.

• [BREAKING]: All flags related to license keys (--license.key and --license.key-file) have been removed.
• [FEATURE]: All features that previously required a license key are now fully unlocked without a key.
• [FEATURE]: PromLens releases are now published for a wide range of architectures and platforms, both as binary tarballs and as Docker images. See the GitHub releases page and the Docker Hub page for details.
• [FEATURE]: The PromLens web server now supports TLS, authentication, and other web-based settings, using a new --web.config.file flag that works like the equivalent flag in Prometheus.
• [FEATURE]: The PromLens web server now supports listening on multiple addresses by repeating the --web.listen-address flag.
• [FEATURE]: The PromLens web server now supports using a systemd activation listener by using the --web.systemd-socket flag.
• [ENHANCEMENT]: When pressing <Enter> in the expression text editor, the query data for the Graph / Table / Explain tabs in the node visualizer pane are now refreshed even if the expression has not changed.
• [ENHANCEMENT]: Several PromLabs-specific references and pages have been removed from the web UI.
• [ENHANCEMENT]: Various Go- and JavaScript-related dependencies have been updated to their latest versions, which also adds support for the day_of_year() PromQL function.
