// deciding whether to use the Go collector:
//
// 1. The performance impact of stopping the world is the more relevant the more
// frequently metrics are collected. However, with Go1.9 or later the
// stop-the-world time per metrics collection is very short (~25µs) so that the
// performance impact will only matter in rare cases. However, with older Go
// versions, the stop-the-world duration depends on the heap size and can be
// quite significant (~1.7 ms/GiB as per
// https://go-review.googlesource.com/c/go/+/34937).
//
// 2. During an ongoing GC, nothing else can stop the world. Therefore, if the
// metrics collection happens to coincide with GC, it will only complete after
// GC has finished. Usually, GC is fast enough to not cause problems. However,
// with a very large heap, GC might take multiple seconds, which is enough to
// cause scrape timeouts in common setups. To avoid this problem, the Go
// collector will use the memstats from a previous collection if
// runtime.ReadMemStats takes more than 1s. However, if there are no previously
// collected memstats, or their collection is more than 5m ago, the collection
// will block until runtime.ReadMemStats succeeds. (The problem might be solved

- [BUGFIX] Calling `Close` more than once on a querier returns an error instead of a panic.
- [BUGFIX] Don't panic and recover nicely when running out of disk space.
- [BUGFIX] Correctly handle empty labels.
- [BUGFIX] Don't crash on an unknown tombstone ref.
- [ENHANCEMENT] Re-add FromData function to create a chunk from bytes. It is used by Cortex and Thanos.
- [ENHANCEMENT] Simplify mergedPostings.Seek.
- [FEATURE] Added `currentSegment` metric for the current WAL segment it is being written to.
## 0.7.1
