New Features

36991f0 Add support for Azure Blob Storage backend (#340) @pedrosaraiva
bc11b55 Add Query Frontend module to allow scaling the query path (#400) @annanay25

Breaking Changes

9e0e05a The gRPC signature from distributors to ingesters has changed. This is a breaking change when running in microservices mode with separate distributors and ingesters. To prevent errors first upgrade all ingesters, which adds the new gRPC endpoint, then upgrade the distributors. (#430) @mdisibio
dd7a18e Removed disk-based caching. Please migrate to redis or memcached. (#441) @joe-elliott
a796195 The ingestion_max_batch_size setting has been renamed to ingestion_burst_size. (#445) @mdisibio
