# Revision history for mmzk-typeid
## 0.3.0.0 -- 2023-07-17
* Use 'uuid-types' package's `UUID` instead of a custom type.
* `Data.UUID.V7` only retains the generation functions.
* Other modules are not affected by this change.
* Add `Read` and `Hashable` instances for `TypeID` and `KindID`.
* Move `ValidPrefix` and `ToPrefix` to `Data.KindID.Class` module.
* They are no longer exported from `Data.KindID`.
* Remove deprecated functions `unUUID`, `parseStringWithPrefix`,
`parseTextWithPrefix`, `parseByteStringWithPrefix`, `nil`, and `decorate`.
* Re-implement `Show` instances for `TypeID` and `KindID` using pretty-print
`toString`.
* Implement `TypeID` generation based on stateless `UUID`v7.
* It is faster but does not guarantee monotonicity if multiple processes are
generating `TypeID`s at the same time.
* Introduce unsafe `TypeID` and `KindID` functions for parsing and generating.
They do not check the validity of the input and only behave well when the
input is guaranteed to be valid.
* Add validity check on `TypeID` and `KindID` generation.
* `checkID` checks the prefix and the `UUID`'s version and variant.
* `checkIDWithEnv` also checks that the `UUID` is generated in the past.
* Deprecate `nilTypeID` and `nilKindID` since they are not useful.
* Fix typos in the documentation.
* More tests.
## 0.2.0.0 -- 2023-07-14
* Implement `KindID` to take arbitrary prefix type.
* It can be a `Symbol` as before, but it can also be any type that implements
`ToPrefix` which dictates how to translate the prefix type to a `Symbol`.
* Fix orphan instances for `TypeID` and `KindID`.
* Add `FromJSONKey` and `ToJSONKey` instances for `TypeID` and `KindID`.
* Introduce `IDType` class to unify the `getPrefix`, `getUUID`, and `getTime`
functions of `TypeID` and `KindID`.
* Introduce `IDConv` class to unify the various conversion functions between
`TypeID`/`KindID` and `String`/`Text`/`ByteString`.
* The original concrete functions remain, and the class is provided as an
alternative.
* Make the generation functions work with any `MonadIO` than just `IO`.
* Introduct `IDGen` class to unify the generation functions for `TypeID` and
`KindID`.
* The original concrete functions remain, and the class is provided as an
alternative.
* Deprecate `unUUID`, `parseStringWithPrefix`, `parseTextWithPrefix`,
`parseByteStringWithPrefix`, `nil`, and `decorate`. They are either replaced
by functions of other names or are no longer necessary.
* They will be removed in the next major version.
* The `UUID` type is expected to be removed in the next major version in favour
of the type from the 'uuid-types' package.
* More tests.
## 0.1.0.0 -- 2023-07-11
* First version. Released on an unsuspecting world.
* Implement `TypeID` as specified at https://github.com/jetpack-io/typeid.
* Add unit tests.
* Add type-level `TypeID` prefixes.
* Add `FromJSON` and `ToJSON` instances for `TypeID` and `KindID`.
