InfluxDB 1.8.0 has been released with several key features, including Flux v0.65 for interactive query within the database, direct access through API and InfluxCLI, join data across multiple measurements, buckets, or data sources, and support for geohashes and geo-temporal data in an experimental state. The release also includes operational improvements such as custom HTTP endpoint connection using -url-prefix, offline series compaction capability, and security enhancements like TLS 1.3 configuration and bound parameter support. Additionally, the InfluxDB Enterprise 1.8 release will be tested within the InfluxDB Cloud environment first before being released later this month.
