## v1.2.0
|
||||
|
||||
### Added
|
||||
|
||||
- Error enums which can be accessed using `Root.Error.(soup.Error).Type`. Refer to `examples/errors`.
|
||||
|
||||
## v1.1.0
|
||||
|
||||
### Added
|
||||
|
||||
- Cookies can be added to the HTTP request, either via the `Cookies` map or the `Cookie()` function
|
||||
- Function `GetWithClient()` provides the ability to send the request with a custom HTTP client
|
||||
- Function `FindStrict()` finds the first instance of the mentioned tag with the exact matching values of the provided attribute (previously `Find()`)
|
||||
- Function `FindAllStrict()` finds all the instances of the mentioned tag with the exact matching values of the attributes (previously `FindAll()`)
|
||||
|
||||
## Changed
|
||||
|
||||
- Function `Find()` now finds the first instance of the mentioned tag with any matching values of the provided attribute.
|
||||
- Function `FindAll()` now finds all the instances of the mentioned tag with any matching values of the provided attribute.

# Changelog
|
||||
All notable changes to this project will be documented in this file.
|
||||
|
||||
This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
||||
|
||||
The format of this file is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
|
||||
but only releases after v1.0.3 properly adhere to it.
|
||||
|
||||
|
||||
## [1.2.0] - 2021-01-27
|
||||
### Added
|
||||
- HSLuv and HPLuv color spaces (#41, #51)
|
||||
- CIE LCh(uv) color space, called `LuvLCh` in code (#51)
|
||||
- JSON and envconfig serialization support for `HexColor` (#42)
|
||||
- `DistanceLinearRGB` (#53)
|
||||
|
||||
### Fixed
|
||||
- RGB to/from XYZ conversion is more accurate (#51)
|
||||
- A bug in `XYZToLuvWhiteRef` that only applied to very small values was fixed (#51)
|
||||
- `BlendHCL` output is clamped so that it's not invalid (#46)
|
||||
- Properly documented `DistanceCIE76` (#40)
|
||||
- Some small godoc fixes
|
||||
|
||||
|
||||
## [1.0.3] - 2019-11-11
|
||||
- Remove SQLMock dependency
|
||||
|
||||
|
||||
## [1.0.2] - 2019-04-07
|
||||
- Fixes SQLMock dependency
|
||||
|
||||
|
||||
## [1.0.1] - 2019-03-24
|
||||
- Adds support for Go Modules
|
||||
|
||||
|
||||
## [1.0.0] - 2018-05-26
|
||||
- API Breaking change in `MakeColor`: instead of `panic`ing when alpha is zero, it now returns a secondary, boolean return value indicating success. See [the color.Color interface](#the-colorcolor-interface) section and [this FAQ entry](#q-why-would-makecolor-ever-fail) for details.
|
||||
|
||||
|
||||
## [0.9.0] - 2018-05-26
|
||||
- Initial version number after having ignored versioning for a long time :)
|
||||
File diff suppressed because one or more lines are too long
