This release contains 112 contributions from 51 contributors. Thank you!

Some notable new features in this release are:

• Streaming capabilities in Querier for metadata APIs.
• Experimental shuffle sharding support for compactor, which enables parallel compaction.

Some notable enhancement and bug fixes in this release are:

• New block storage configurations for Azure that allows reduction in memory usage.
• Memory leak fix in Distributor and Ruler.
• Jitter in Memberlist rejoin interval that reduces CPU utilization during rejoin.
