Grafana version 1.7.0-rc1 introduces significant new features and architectural changes, including the ability to use InfluxDB for dashboard storage and as a data source for annotations, alongside improvements in series aliasing. Additionally, Elasticsearch can now serve as an annotation data source, and new graph legend options are available. The release also enhances documentation with new guides and includes various small improvements and fixes aimed at facilitating future development. Torkel Ödegaard, the lead developer, has committed to working on Grafana full-time without current sponsorship, considering options like offering a premium or hosted version to sustain development. He invites companies to sponsor development for recognition benefits and expresses a willingness to engage in talks and coaching about Grafana and related topics.
