TL;DR: Store LRU cache is no longer leaking, Upgraded Thanos UI to Prometheus 2.9, Fixed auto-downsampling, Moved to Go 1.12.5 and more.

This version moved tarballs to Golang 1.12.5 from 1.11 as well, so same warning applies if you use container_memory_usage_bytes from cadvisor. Use container_memory_working_set_bytes instead.

breaking As announced couple of times this release also removes gossip with all configuration flags (--cluster.*).

Fixed

  • #1142 fixed major leak on store LRU cache for index items (postings and series).

  • #1157 querier correctly handles duplicated stores when some store changes external labels in place.

Added

  • #1094 Allow configuring the response header timeout for the S3 client.

Changed
