## master / unreleased
- `LastCheckpoint` used to return just the segment name and now it returns the full relative path.
- `NewSegmentsRangeReader` can now read over miltiple wal ranges by using the new `SegmentRange` struct.
- `CorruptionErr` now also exposes the Segment `Dir` which is added when displaying any errors.
- `Head.Init()` is changed to `Head.Init(minValidTime int64)` where `minValidTime` is taken from the maxt of the last persisted block and any samples below `minValidTime` will not be loaded from the wal in the head. The same value is used when using the `Heah.Appender()` to disallow adding samples below the `minValidTime` timestamp. This change was nececary to fix a bug where a `Snapshot()` with the head included would create a block with custom time range(not bound to the default time ranges) and the next block population from the head would create an overlapping block.

## 0.3.0
- [CHANGE] `LastCheckpoint()` used to return just the segment name and now it returns the full relative path.
- [CHANGE] `NewSegmentsRangeReader()` can now read over miltiple wal ranges by using the new `SegmentRange{}` struct.
- [CHANGE] `CorruptionErr{}` now also exposes the Segment `Dir` which is added when displaying any errors.
- [CHANGE] `Head.Init()` is changed to `Head.Init(minValidTime int64)`
- [CHANGE] `SymbolTable()` renamed to `SymbolTableSize()` to make the name consistent with the `Block{ symbolTableSize uint64 }` field.
- [CHANGE] `wal.Reader{}` now exposes `Segment()` for the current segment being read and `Offset()` for the current offset.
