0.8.0

Requirements

• PostgreSQL: 12.x, 13.x, 14.x., 15.x
• TimescaleDB: >= 2.9.1 single-node (multi-node is not supported in this release)
• Promscale Connector: 0.17.0

Changed

• Maintenance jobs were separated from one another. The behavior of the old
  prom_api.config_maintenance_jobs call changed and it sets identical parameters
  for each job type (e.g. parallelism 2 means each job type has 2 jobs, not 2 jobs in total).
  There is also the new prom_api.config_maintenance_jobs that allows configuring
  them individually. Finally, the new default worker allocation is 2 metrics retention
  jobs, 3 jobs for metrics compression and 1 job for traces retention. [#555] [#588]
• Removed disk size-related columns from prom_info.metric.
  Added prom_info.metric_detail which includes the disk size-related columns.
  Improved the performance of these. [#547]
• The metric compression job now only locks metrics that are known to have chunks
  that need to be compressed [#576]
• Renamed _ps_catalog.chunks_to_freeze to _ps_catalog.compressed_chunks_to_freeze [#595]
• All docker images upgraded to use TimescaleDB 2.9 [#598]
• The extension is updated to add support for PostgreSQL 15. [#590]

Added

• Telemetry for active series and last updated [#534]
• Added _ps_catalog.compressed_chunks_missing_stats view [#595]

Fixed

• Column conflict when creating a metric view with a label called series
  [#559]
