================================
Bugfixes
- Fix missing fieldnorms for u64, i64, f64, bool, bytes and date [1620](https://github.com/quickwit-oss/tantivy/pull/1620) (PSeitz)
- Fix interpolation overflow in linear interpolation fastfield codec [1480](https://github.com/quickwit-oss/tantivy/pull/1480) (PSeitz fulmicoton)

Features/Improvements
- Add support for `IN` in queryparser , e.g. `field: IN [val1 val2 val3]` [1683](https://github.com/quickwit-oss/tantivy/pull/1683) (trinity-1686a)
- Skip score calculation, when no scoring is required [1646](https://github.com/quickwit-oss/tantivy/pull/1646) (PSeitz)
- Limit fast fields to u32 (`get_val(u32)`) [1644](https://github.com/quickwit-oss/tantivy/pull/1644) (PSeitz)
- The `DateTime` type has been updated to hold timestamps with microseconds precision.
`DateOptions` and `DatePrecision` have been added to configure Date fields. The precision is used to hint on fast values compression. Otherwise, seconds precision is used everywhere else (i.e terms, indexing) [1396](https://github.com/quickwit-oss/tantivy/pull/1396) (evanxg852000)
- Add IP address field type [1553](https://github.com/quickwit-oss/tantivy/pull/1553) (PSeitz)
- Add boolean field type [1382](https://github.com/quickwit-oss/tantivy/pull/1382) (boraarslan)
- Remove Searcher pool and make `Searcher` cloneable. (PSeitz)
- Validate settings on create [1570](https://github.com/quickwit-oss/tantivy/pull/1570) (PSeitz)
- Detect and apply gcd on fastfield codecs [1418](https://github.com/quickwit-oss/tantivy/pull/1418) (PSeitz)
- Doc store
- use separate thread to compress block store [1389](https://github.com/quickwit-oss/tantivy/pull/1389) [#1510](https://github.com/quickwit-oss/tantivy/pull/1510) (PSeitz fulmicoton)
- Expose doc store cache size [1403](https://github.com/quickwit-oss/tantivy/pull/1403) (PSeitz)
- Enable compression levels for doc store [1378](https://github.com/quickwit-oss/tantivy/pull/1378) (PSeitz)
- Make block size configurable [1374](https://github.com/quickwit-oss/tantivy/pull/1374) (kryesh)
- Make `tantivy::TantivyError` cloneable [1402](https://github.com/quickwit-oss/tantivy/pull/1402) (PSeitz)
- Add support for phrase slop in query language [1393](https://github.com/quickwit-oss/tantivy/pull/1393) (saroh)
- Aggregation
- Add aggregation support for date type [1693](https://github.com/quickwit-oss/tantivy/pull/1693)(PSeitz)
- Add support for keyed parameter in range and histgram aggregations [1424](https://github.com/quickwit-oss/tantivy/pull/1424) (k-yomo)
- Add aggregation bucket limit [1363](https://github.com/quickwit-oss/tantivy/pull/1363) (PSeitz)
- Faster indexing
- [1610](https://github.com/quickwit-oss/tantivy/pull/1610) (PSeitz)
- [1594](https://github.com/quickwit-oss/tantivy/pull/1594) (PSeitz)
- [1582](https://github.com/quickwit-oss/tantivy/pull/1582) (PSeitz)
- [1611](https://github.com/quickwit-oss/tantivy/pull/1611) (PSeitz)
- Added a pre-configured stop word filter for various language [1666](https://github.com/quickwit-oss/tantivy/pull/1666) (adamreichold)

0.18.1

================================
- Hotfix: positions computation. 1629 (fmassot, fulmicoton, PSeitz)

0.18

================================

- For date values `chrono` has been replaced with `time` (uklotzde) 1304 :
- The `time` crate is re-exported as `tantivy::time` instead of `tantivy::chrono`.
- The type alias `tantivy::DateTime` has been removed.
- `Value::Date` wraps `time::PrimitiveDateTime` without time zone information.
- Internally date/time values are stored as seconds since UNIX epoch in UTC.
- Converting a `time::OffsetDateTime` to `Value::Date` implicitly converts the value into UTC.
If this is not desired do the time zone conversion yourself and use `time::PrimitiveDateTime`
directly instead.
- Add [histogram](https://github.com/quickwit-oss/tantivy/pull/1306) aggregation (PSeitz)
- Add support for fastfield on text fields (PSeitz)
- Add terms aggregation (PSeitz)
- Add support for zstd compression (kryesh)

0.17

================================

- LogMergePolicy now triggers merges if the ratio of deleted documents reaches a threshold (shikhar fulmicoton) [115](https://github.com/quickwit-oss/tantivy/issues/115)
- Adds a searcher Warmer API (shikhar fulmicoton)
- Change to non-strict schema. Ignore fields in data which are not defined in schema. Previously this returned an error. 1211
- Facets are necessarily indexed. Existing index with indexed facets should work out of the box. Index without facets that are marked with index: false should be broken (but they were already broken in a sense). (fulmicoton) 1195 .
- Bugfix that could in theory impact durability in theory on some filesystems [1224](https://github.com/quickwit-oss/tantivy/issues/1224)
- Schema now offers not indexing fieldnorms (lpouget) [922](https://github.com/quickwit-oss/tantivy/issues/922)
- Reduce the number of fsync calls [1225](https://github.com/quickwit-oss/tantivy/issues/1225)
- Fix opening bytes index with dynamic codec (PSeitz) [1278](https://github.com/quickwit-oss/tantivy/issues/1278)
- Added an aggregation collector for range, average and stats compatible with Elasticsearch. (PSeitz)
- Added a JSON schema type fulmicoton [1251](https://github.com/quickwit-oss/tantivy/issues/1251)
- Added support for slop in phrase queries halvorboe [1068](https://github.com/quickwit-oss/tantivy/issues/1068)

0.16.2

================================

- Bugfix in FuzzyTermQuery. (transposition_cost_one was not doing anything)

0.16.1

========================

- Major Bugfix on multivalued fastfield. 1151
- Demux operation (PSeitz)
