# Sonic Changelog

<!-- markdownlint-disable no-duplicate-heading -->

## [Unreleased]

<!-- WARN: Do not move the next line and add changelog entries **under** it.
       It’s used by `task release:*` when updating the changelog. -->
[Unreleased]: https://github.com/valeriansaliou/sonic/compare/v1.7.2...HEAD

## [1.7.2] (2026-07-06)

[1.7.2]: https://github.com/valeriansaliou/sonic/compare/v1.7.1...v1.7.2

### Bug Fixes

* fix(core): Perform implicit `AND` when `QUERY`ing an ID (in `fe3d2cc`)

## [1.7.1] (2026-07-02)

[1.7.1]: https://github.com/valeriansaliou/sonic/compare/v1.7.0...v1.7.1

CI failed because we moved `debian/` to `packaging/debian/` and added Docker
cross-compilation for `arm64` without installing `docker buildx`.

This release is exactly like `1.7.0`, it’s just for CD purposes.

## [1.7.0] (2026-07-01)

[1.7.0]: https://github.com/valeriansaliou/sonic/compare/v1.6.0...v1.7.0

This release was focused on making improvements to search results
(see [Milestone #20 “v1.7.x - Better search results (non-breaking)”][milestone-20]).
We benchmarked the changes, and concluded the performance impact of all those
changes is negligible. If you notice something now being noticeably slower,
please tell us as it might be a bug!

[milestone-20]: https://github.com/valeriansaliou/sonic/milestone/20

### Changes

* Implement proper case folding (in `f67f964`)
* Rework `QUERY` results ranking algorithm (see [Pull Request #355 “No implicit `AND`”](https://github.com/valeriansaliou/sonic/pull/355))
* Logging improvements
* More tests

### New Features

* Add support for diacritics-insensitive search (in `3d38caa`, `2379b0a`)
* Add support for stemming (in `db83731`)
* Introduce an official Rust client (in `5e1849d`)
* bench: Introduce server benchmarks (in `8b9ec98`)
* test: Introduce non-regression tests

### Bug Fixes

* Fix max typo correction in `QUERY` (in `097a752`)
* config: Fix non-string parsing from env (in `b17daad`)
* server: Fix buffer overflow detection code (in `c85d97b`)

## [1.6.0] (2026-06-03)

[1.6.0]: https://github.com/valeriansaliou/sonic/compare/v1.5.1...v1.6.0

### Changes

* Separate Sonic’s core into a library (in `1d4c49e`, `99b3955`, `693babb`)
* config: Deprecate `channel.search` in favor of `search` (in `b2e7015`)
* Dependency updates (fixes CVEs):
  * Update dependencies to fix GHSA-3pv8-6f4r-ffg2 (in `a2d0f00`, `52042b6`)

### New Features

* Release for Red Hat Enterprise Linux (RHEL) (in `0e983a3`)
* test: Introduce Rust integration tests (in `88e629b`)

## [1.5.1] (2026-05-21)

[1.5.1]: https://github.com/valeriansaliou/sonic/compare/v1.5.0...v1.5.1

### Bug Fixes

Because of partial CI failures we ended up releasing some versions but not
all (e.g. “error: crate sonic-server@1.5.0 already exists on crates.io index”).
We will yank `1.5.0` on crates.io and publish `1.5.1` instead.

## [1.5.0] (2026-05-21)

[1.5.0]: https://github.com/valeriansaliou/sonic/compare/v1.4.9...v1.5.0

### Removals

* Stop GPG-signing binaries, since it consumes human time when releasing (in `05b8ddb`)

### Changes

* Dependency updates (fixes CVEs):
  * Bump `clap` from `3` to `4` (in `00a373d`)
  * Bump `hashbrown` from `0.14` to `0.17` (in `47663c6`)
  * Bump `jieba-rs` from `0.6` to `0.9` (in `69f3c08`, `c096f4f`)
  * Bump `lindera` from `0.27` to `0.31` (in `b0acdc3`)
  * Bump `nix` from `0.18` to `0.31` (in `28e2d2c`)
  * Bump `rand` from `0.8` to `0.10` (in `6e9577f`)
  * Bump `rocksdb` from `0.21` to `0.24` (in `dd3a0e8`, `266af2f`)

  * Bump `twox-hash` from `1` to `2` (in `714dae4`)
  * Bump `whatlang` from `0.16` to `0.18` (in `38a2ed6`)
  * Use `windows-sys` instead of `winapi` (in `26d45f6`, `f0195b7`)
  * Relax some dependency version requirements (in `966cdf7`)
  * Run `cargo update` to fix CVEs (in `c50a16c`, `c83278c`)
  * Run `cargo upgrade --pinned` (in `9bee794`)
  * ci: Update third-party actions (in `722bfec`, `93f0e67`)
  * ci: Pin third-party actions (in `8449b15`)
  * ci: Build and release using locked dependency versions (in `630ac52`)

### New Features

* Stopwords:
  * Add Malayalam (MAL) stopwords (in `e3ec190`)
  * Add Serbian (SRP) stopwords (in `b0c1f66`, `a2bf0c5`)
  * config: Support environment-based configuration (in `cc99461`)

## 1.4.9 (2024-06-16)

### Changes

* Update Rust code style to conform to new `rustc` requirements (preventing builds on `rustc 1.79.0` and further) [[@jaseemabid](https://github.com/jaseemabid), [#321](https://github.com/valeriansaliou/sonic/pull/321)].

## 1.4.8 (2023-12-14)

### Changes

* Pull out the `arm64` platform from the Docker image, since it does not build in acceptable time via GitHub Actions due to using QEMU emulation (will wait that GitHub Actions provides a native `arm64` runner) [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.4.7 (2023-12-14)

### Bug Fixes

* Fixed non-working `arm64` builds due to hardcoded `x86_64-unknown-linux-gnu` Rust target in the `Dockerfile` [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.4.6 (2023-12-14)

### New Features

* The Docker image is now also available for the `arm64` platform, in addition to `amd64` [[@PovilasID](https://github.com/PovilasID), [#310](https://github.com/valeriansaliou/sonic/pull/310)].

## 1.4.5 (2023-12-11)

### Bug Fixes

* Fixed an issue where system clock can move back to the past on a virtualized system, resulting in client threads entering a crash loop due to mutex poisoning [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.4.4 (2023-12-08)

### Bug Fixes

* Fixed `rocksdb` not building due to a `rust-bindgen` version which was not compatible with `clang` version 16 [[@anthonyroussel](https://github.com/anthonyroussel), [#316](https://github.com/valeriansaliou/sonic/pull/316)].

### Changes

* Dependencies have been bumped to latest versions (namely: `rocksdb`, `toml`, `regex-syntax`, `hashbrown`, `lindera-core`, `lindera-dictionary`, `lindera-tokenizer`) [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.4.3 (2023-09-04)

### Changes

* Publish `.deb` packages for Debian 12 on `x86_64` architecture [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.4.2 (2023-09-04)

### Changes

* Produce `glibc` builds from GitHub Actions whenever a new Sonic version gets released [[@valeriansaliou](https://github.com/valeriansaliou)].
* Pull out `tokenizer-japanese` from the default features, as it x10 the final binary size [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.4.1 (2023-08-12)

### New Features

* Added support for Japanese word segmentation in tokenizer (note that as this adds quite some size overhead to the final binary size, the feature `tokenizer-japanese` can be disabled when building Sonic) [[@nmkj-io](https://github.com/nmkj-io), [#311](https://github.com/valeriansaliou/sonic/pull/311)].

## 1.4.0 (2022-10-20)

* Fixed typos in code and documentation [[@kianmeng](https://github.com/kianmeng), [#294](https://github.com/valeriansaliou/sonic/pull/294)].

### Changes

* Replaced Docker source image from Debian Slim to lighter Google distroless image [[@0x0x1](https://github.com/0x0x1), [#282](https://github.com/valeriansaliou/sonic/pull/282)].

### New Features

* Added an index enumeration `LIST` command to Sonic Channel [[@trkohler](https://github.com/trkohler), [#293](https://github.com/valeriansaliou/sonic/pull/293)].

## 1.3.5 (2022-07-10)

### Bug Fixes

* Rolled back `rocksdb` version, as the latest version does not link properly in `--release` mode [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.3.4 (2022-07-10)

### Changes

* Dependencies have been bumped to latest versions (namely: `rocksdb`, `clap`, `regex`) [[@valeriansaliou](https://github.com/valeriansaliou)].

* Moved the release pipeline to GitHub Actions [[@valeriansaliou](https://github.com/valeriansaliou)].

### New Features

* The language detection system is now about 2x faster (due to the upgrade of `whatlang` past `v0.14.0`) [[@valeriansaliou](https://github.com/valeriansaliou)].
* Added Armenian stopwords [[@valeriansaliou](https://github.com/valeriansaliou)].

### Bug Fixes

* Fixed Norwegian stopwords [[@valeriansaliou](https://github.com/valeriansaliou), [#239](https://github.com/valeriansaliou/sonic/issues/239)].

### Changes

* Code has been formatted according to `clippy` recommendations. This does not change the way Sonic behaves [[@pleshevskiy](https://github.com/pleshevskiy), [#233](https://github.com/valeriansaliou/sonic/pull/233)].

### New Features

* Added support for Chinese word segmentation in tokenizer (note that as this adds quite some size overhead to the final binary size, the feature `tokenizer-chinese` can be disabled when building Sonic) [[@vincascm](https://github.com/vincascm), [#209](https://github.com/valeriansaliou/sonic/pull/209)].

## 1.3.0 (2020-06-27)

### Changes

* Added support for Slovak, which is now auto-detected from terms [[@valeriansaliou](https://github.com/valeriansaliou), [19412ce](https://github.com/valeriansaliou/sonic/commit/19412ce05a802ef1e6054b751faaef50cab5d36b)].
* Added Slovak stopwords [[@valeriansaliou](https://github.com/valeriansaliou), [19412ce](https://github.com/valeriansaliou/sonic/commit/19412ce05a802ef1e6054b751faaef50cab5d36b)].

## 1.2.4 (2020-06-25)

### Bug Fixes

* Fixed multiple deadlocks, which where not noticed in practice by running Sonic at scale, but that are still theoretically possible [[@BurtonQin](https://github.com/BurtonQin), [#213](https://github.com/valeriansaliou/sonic/pull/213), [#211](https://github.com/valeriansaliou/sonic/pull/211)].

### Changes

* Added support for Latin, which is now auto-detected from terms [[@valeriansaliou](https://github.com/valeriansaliou), [e6c5621](https://github.com/valeriansaliou/sonic/commit/e6c5621ba0fabe83b8bc060824951006b373dc3f)].

## 1.2.3 (2019-10-14)

### Changes

* RocksDB compression algorithm has been changed from LZ4 to Zstandard, for a slightly better compression ratio, and much better read/write performance; this will be used for new SST files only [[@valeriansaliou](https://github.com/valeriansaliou), [cd4cdfb](https://github.com/valeriansaliou/sonic/commit/cd4cdfb756ae9eccd43dc7e73d2c115b33297714)].

## 1.2.2 (2019-07-12)

### Bug Fixes

### Changes

* Optimized some aspects of FST consolidation and pending operations management [[@valeriansaliou](https://github.com/valeriansaliou), [#156](https://github.com/valeriansaliou/sonic/issues/156)].

## 1.2.1 (2019-07-08)

### Changes

* FST graph consolidation is now able to ignore new words when the graph is over configured limits, which are set with the new `store.fst.graph.max_size` and `store.fst.graph.max_words` configuration variables [[@valeriansaliou](https://github.com/valeriansaliou), [53db9c1](https://github.com/valeriansaliou/sonic/commit/53db9c186630a6751c0a85e610cebabace1aee2b)].
* An integration testing infrastructure has been added to the Sonic automated test suite [[@vilunov](https://github.com/vilunov), [#154](https://github.com/valeriansaliou/sonic/pull/154)].
* Configuration values can now be sourced from environment variables, using the `${env.VARIABLE}` syntax in `config.cfg` [[@perzanko](https://github.com/perzanko), [#148](https://github.com/valeriansaliou/sonic/pull/148)].

## 1.2.0 (2019-05-03)

### Bug Fixes

* Fixed a rare deadlock occurring when 3 concurrent operations get executed on different threads for the same collection, in the following timely order: `PUSH` then `FLUSHB` then `PUSH` [[@valeriansaliou](https://github.com/valeriansaliou), [d96546b](https://github.com/valeriansaliou/sonic/commit/d96546bd9d8b79332df1106766377e4a4acebd50)].

### Changes

* Reworked the KV store manager to perform periodic memory flushes to disk, thus reducing startup time [[@valeriansaliou](https://github.com/valeriansaliou), [6713488](https://github.com/valeriansaliou/sonic/commit/6713488af3543bca33be6e772936f9668430ba86)].
* Stop accepting Sonic Channel commands when shutting down Sonic [[@valeriansaliou](https://github.com/valeriansaliou), [#131](https://github.com/valeriansaliou/sonic/issues/131)].

### New Features

* Introduced a server statistics `INFO` command to Sonic Channel [[@valeriansaliou](https://github.com/valeriansaliou), [#70](https://github.com/valeriansaliou/sonic/issues/70)].
* Added the ability to disable the lexer for a command with the command modifier `LANG(none)` [[@valeriansaliou](https://github.com/valeriansaliou), [#108](https://github.com/valeriansaliou/sonic/issues/108)].
* Added a backup and restore system for both KV and FST stores, which can be triggered over Sonic Channel with `TRIGGER backup` and `TRIGGER restore` [[@valeriansaliou](https://github.com/valeriansaliou), [#5](https://github.com/valeriansaliou/sonic/issues/5)].
* Added the ability to disable KV store WAL (Write-Ahead Log) with the `write_ahead_log` option, which helps limit write wear on heavily loaded SSD-backed servers [[@valeriansaliou](https://github.com/valeriansaliou), [#130](https://github.com/valeriansaliou/sonic/issues/130)].

## 1.1.9 (2019-03-29)

### Bug Fixes

* RocksDB has been bumped to `v5.18.3`, which fixes a dead-lock occurring in RocksDB at scale when a compaction task is ran under heavy disk writes (ie. disk flushes). This dead-lock was causing Sonic to stop responding to any command issued for the frozen collection. This dead-lock was due to a bug in RocksDB internals (not originating from Sonic itself) [[@baptistejamin](https://github.com/baptistejamin), [19c4a10](https://github.com/baptistejamin/sonic/commit/19c4a104a6d6aaed1dd9beb2e51d2639627825cd)].

### Changes

* Reworked the `FLUSHB` command internals, which now use the atomic `delete_range()` operation provided by RocksDB `v5.18` [[@valeriansaliou](https://github.com/valeriansaliou), [660f8b7](https://github.com/valeriansaliou/sonic/commit/660f8b714d968400fb9f88a245752dca02249bf7)].

### New Features

* Added the `LANG(<locale>)` command modifier for `QUERY` and `PUSH`, that lets a Sonic Channel client force a text locale (instead of letting the lexer system guess the text language) [[@valeriansaliou](https://github.com/valeriansaliou), [#75](https://github.com/valeriansaliou/sonic/issues/75)].
* The FST word lookup system, used by the `SUGGEST` command, now support all scripts via a restricted Unicode range forward scan [[@valeriansaliou](https://github.com/valeriansaliou), [#64](https://github.com/valeriansaliou/sonic/issues/64)].

## 1.1.8 (2019-03-27)

### Bug Fixes

* A store acquire lock has been added to prevent 2 concurrent threads from opening the same collection at the same time [[@valeriansaliou](https://github.com/valeriansaliou), [2628077](https://github.com/valeriansaliou/sonic/commit/2628077ebe7e24155975962471e7653745a0add7)].

## 1.1.7 (2019-03-27)

### Bug Fixes

* A superfluous mutex was removed from KV and FST store managers, in an attempt to solve a rare dead-lock occurring on high-traffic Sonic setups in the KV store [[@valeriansaliou](https://github.com/valeriansaliou), [60566d2](https://github.com/valeriansaliou/sonic/commit/60566d2f087fd6725dba4a60c3c5a3fef7e8399b)].

## 1.1.6 (2019-03-27)

### Changes

* Reverted changes made in `v1.1.5` regarding the open files `rlimit`, as this can be set from outside Sonic [[@valeriansaliou](https://github.com/valeriansaliou), [f6400c6](https://github.com/valeriansaliou/sonic/commit/f6400c61a9a956130ae0bdaa9a164f4955cd2a18)].
* Added Chinese Traditional stopwords [[@dsewnr](https://github.com/dsewnr), [#87](https://github.com/valeriansaliou/sonic/issues/87)].

### Bug Fixes

* Improved the way database locking is handled when calling a pool janitor; this prevents potential dead-locks under high load [[@valeriansaliou](https://github.com/valeriansaliou), [fa78372](https://github.com/valeriansaliou/sonic/commit/fa783728fd27a116b8dcf9a7180740d204b69aa4)].

## 1.1.5 (2019-03-27)

### New Features

* Added the `server.limit_open_files` configuration variable to allow configuring `rlimit` [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.1.4 (2019-03-27)

### Changes

* Added Kannada stopwords [[@dileepbapat](https://github.com/dileepbapat)].
* The Docker image is now much lighter [[@codeflows](https://github.com/codeflows)].

### New Features

* Automatically adjust `rlimit` for the process to the hard limit allowed by the system (allows opening more FSTs in parallel) [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.1.3 (2019-03-25)

### Changes

* Limit the size of words that can hit against the FST graph, as the FST gets slower for long words [[@valeriansaliou](https://github.com/valeriansaliou), [#81](https://github.com/valeriansaliou/sonic/issues/81)].

### Bug Fixes

* Rework Sonic Channel buffer management using a VecDeque (Sonic should now work better in harsh network environments) [[@valeriansaliou](https://github.com/valeriansaliou), [1c2b9c8](https://github.com/valeriansaliou/sonic/commit/1c2b9c8fcd28b033a7cb80d678c388ce78ab989d)].

## 1.1.2 (2019-03-24)

### Changes

* FST graph consolidation locking strategy has been improved even further, based on issues with the previous rework we have noticed at scale in production (now, consolidation locking is done at a lower-priority relative to actual queries and pushes to the index) [[@valeriansaliou](https://github.com/valeriansaliou), [#68](https://github.com/valeriansaliou/sonic/issues/68)].

## 1.1.1 (2019-03-24)

### Changes

* FST graph consolidation locking strategy has been reworked as to allow queries to be executed lock-free when the FST consolidate task takes a lot of time (previously, queries were being deferred due to an ongoing FST consolidate task) [[@valeriansaliou](https://github.com/valeriansaliou), [#68](https://github.com/valeriansaliou/sonic/issues/68)].
* Removed special license clause introduced in `v1.0.2`, Sonic is full `MPL 2.0` now. [[@valeriansaliou](https://github.com/valeriansaliou)]

## 1.1.0 (2019-03-21)

### Breaking Changes

* Change how buckets are stored in a KV-based collection (nest them in the same RocksDB database; this is much more efficient on setups with a large number of buckets - **`v1.1.0` is incompatible with the `v1.0.0` KV database format**) [[@valeriansaliou](https://github.com/valeriansaliou)].

### Changes

* Bump `jemallocator` to version `0.3` [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.0.2 (2019-03-20)

### Changes

* Re-license from `MPL 2.0` to `SOSSL 1.0` (Sonic has a special license clause) [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.0.1 (2019-03-19)

### Changes

* Added automated benchmarks (can be ran via `cargo bench --features benchmark`) [[@valeriansaliou](https://github.com/valeriansaliou)].
* Reduced the time to query the search index by 50% via optimizations (in multiple methods, eg. the lexer) [[@valeriansaliou](https://github.com/valeriansaliou)].

## 1.0.0 (2019-03-18)

### New Features

* Initial Sonic release [[@valeriansaliou](https://github.com/valeriansaliou)].
