hoauth2-2.15.0: CHANGELOG.md

# hoauth2 Changelog

## 2.15.0 (2025-10-05)
- Breaking changes
  - Type and class renames
    - `OAuth2Token` renamed to `TokenResponse`.
    - `TokenRequestAuthenicationMethod` renamed to `ClientAuthenticationMethod`.
    - `HasTokenRequestClientAuthenticationMethod` renamed to `HasClientAuthenticationMethod`.
    - Removed several `Has*` type classes (e.g., `HasOAuth2Key`, `HasOAuthKey` from `HasTokenRequest`).
  - Removed deprecated API in `Network.OAuth2.HttpClient`
    - Deprecated functions have been removed. Use `authGetJSON`/`authGetBS`/`authPostJSON`/`authPostBS` and the `WithAuthMethod` variants with `APIAuthenticationMethod`.
  - Request body encoding behavior
    - `authPostJSON` now sends JSON with `Content-Type: application/json`. If an endpoint requires form-encoded data, use `authPostBS` or construct a custom request body.
  - Import/module path cleanup
    - Consumers should import `Network.OAuth2` (not `Network.OAuth.OAuth2`).
- Behavioral changes and bug fixes
  - Client authentication handling
    - Append `client_id` and `client_secret` for `ClientSecretPost` in client credentials flow.
    - Refresh token flow honors the configured client authentication method.
    - Authorization Code flow supports client authentication methods.
  - Device Authorization flow
    - Updated handling of device authorization requests and polling behavior.
- Refactors and internal cleanup
  - Refactored header handling, simplified URI-to-Request conversion, removed deprecated or unused internals, and general cleanups.
- Dependency changes
  - Allow `microlens` 0.5 (`microlens` >= 0.4 && < 0.6).
  - Raise lower bound to `uri-bytestring` >= 0.4 (< 0.5).
