# Changelog
## v2.1.1.1 - "Matrix Reloaded" (2026-05-08)
Tested on GHC 9.6, 9.8, 9.10, 9.12, and 9.14.
- Fix build on GHC 9.6 by replacing `Data.List.foldl'` import via `Prelude`
with an explicit `List.foldl'` qualified import
([#77](https://github.com/channable/alfred-margaret/pull/77)).
- CI now tests against a matrix of GHC 9.6, 9.8, 9.10, 9.12 and 9.14 to
prevent future regressions.
- Nix: allow selecting the GHC version used by the development environment.
## v2.1.1.0 - "Generically Primitive" (2026-04-24)
Tested on GHC 9.14.1.
- Derive `Generic` for the exposed data types in `Data.Text.AhoCorasick.*`,
`Data.Text.BoyerMoore.*`, `Data.Text.BoyerMooreCI.*` and
`Data.Text.CaseSensitivity` ([#65](https://github.com/channable/alfred-margaret/pull/65)).
- Replace the internal `Data.TypedByteArray` wrapper with `PrimArray` from
`Data.Primitive`; introduces the new internal module `Data.Primitive.Extended`.
- Widen `containers` upper bound to include `0.8`.
- Toolchain: switch development environment and CI to GHC 9.14 and LLVM 19;
add `direnv` support; bump pinned `nixpkgs` and Nix to 2.24.12.
- Update `tested-with` to GHC 9.14.1.
## v2.1.0.2 - "All the bounds!" (2024-09-06)
Publishing requires `cabal` to know the version bounds as well.
## v2.1.0.1 - "Higher bounds!" (2024-09-05)
Tested on GHC 9.6.6.
- Revise dependency bounds ([#62](https://github.com/channable/alfred-margaret/issues/62) thanks @Bodigrim)
- Allow using primitive < 0.9 and vector < 0.14 ([#59](https://github.com/channable/alfred-margaret/pull/59) thanks @rampion)
## v2.1.0.0 - "All The Cases!" (2022-08-31)
- Added a case-insensitive variant of the Boyer-Moore algorithm in the `Data.Text.BoyerMooreCI.*` modules. ([#47](https://github.com/channable/alfred-margaret/pull/47))
- Fixed a bug in the case-insensitive Aho-Corasick replacer where it would
replace the wrong section of the haystack when the needle had a different
byte-length than the matching part of the haystack. ([#47](https://github.com/channable/alfred-margaret/pull/47))
- Allow mapping the payloads of Aho-Corasick automatons. ([#46](https://github.com/channable/alfred-margaret/pull/46))
## v2.0.0.0 - "So Long Surrogates" (2022-05-02)
Switched to text-2.0 which uses UTF-8 encoding internally.
- Removed `Data.Text.Utf8.*` modules
- Replaced `Data.Text.AhoCorasick.*` and `Data.Text.BoyerMoore.*` (previously using UTF-16) with the UTF-8 implementation
## v1.1.2.0 - "ByteArray Boogaloo" (2022-04-21)
Added UTF-8 implementations on a mock `Text` type (in `Data.Text.Utf8`).
- Added `Data.Text.Utf8*` modules
- Moved `CaseSensitivity` to its own `Data.Text.CaseSensitivity` module.
- Added the private module `Data.TypedByteArray` which contains thin wrappers over `ByteArray` and `MutableByteArray`.
- Replaced uses of `Data.Vector.Unboxed.Vector` by `TypedByteArray`.
## v1.1.0.0 - "Moore Features" (2020-10-13)
The most notable addition in this release is the implementation of the Boyer-Moore string search algorithm.
**Compatibility:**
- Extracted the UTF-16 manipulation functions from `Data.Text.AhoCorasick.Automaton` into `Data.Text.Utf16`
- Changed `Data.Text.AhoCorasick.Searcher.Searcher` to remember the case sensitivity used for constructing the searcher
- Removed `Data.Text.AhoCorasick.Searcher.containsAnyIgnoreCase`, the correct implementation is now chosen by `containsAny` based on the case sensitivity of the searcher
Other changes:
- Added `Data.Text.AhoCorasick.Splitter` for splitting a lot of text using the same needle
- Added `Data.Text.BoyerMoore.Automaton`, a UTF-16 implementation of Boyer-Moore
- Added `Data.Text.BoyerMoore.Searcher` for searching for multiple needles at once using Boyer-Moore
- Added `Data.Text.BoyerMoore.Replacer` for replacing text based on the Boyer-Moore search
- Added optional `FromJSON`/`ToJSON` instances for most types (can be toggled via `aeson` cabal flag)
## v1.0.0.0 - "Initial Release" (2019-03-19)
This is the initial open-source release.
- Added `Data.Text.AhoCorasick.Automaton`, a UTF-16 implementation of the Aho-Corasick search algorithm
- Added `Data.Text.AhoCorasick.Searcher`, a bulk search abstraction based on Aho-Corasick
- Added `Data.Text.AhoCorasick.Replacer`, a bulk replace abstraction based on Aho-Corasick
