 - [#3431](https://github.com/thanos-io/thanos/pull/3431) Store: Added experimental support to lazy load index-headers at query time. When enabled via `--store.enable-index-header-lazy-reader` flag, the store-gateway will load into memory an index-header only once it's required at query time. Index-header will be automatically released after `--store.index-header-lazy-reader-idle-timeout` of inactivity.

 - [#3437](https://github.com/thanos-io/thanos/pull/3437) StoreAPI: Added `hints` field to `LabelNamesResponse` and `LabelValuesResponse`. Hints in an opaque data structure that can be used to carry additional information from the store and its content is implementation specific.
