# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [0.2.4] - 2026-02-08

### Added
- **Auth**: Expanded `FirebaseTokenClaims` to include standard fields like `name`, `picture`, `email`, `email_verified`, and `provider_id`.

### Changed
- **Auth**: Refactored `PublicKeyManager` to cache `DecodingKey` objects instead of raw PEM strings, improving performance during token verification.
- **Auth**: Updated timestamp fields in `FirebaseTokenClaims` from `usize` to `u64` for better compatibility and precision.
- **Refactor**: Improved code formatting and import organization across the `auth` module.

## [0.2.3] - 2026-02-06

### Added
- **Testing**: Significantly expanded CRUD test coverage for Auth, Firestore, Storage, Messaging, and Remote Config.

### Changed
- **Messaging**: Refactored `FirebaseMessaging` to support mock URLs for all API endpoints.
- **Firestore**: Removed unused `collection_id` from `Query` struct.
- **Dependencies**: Updated various dependencies including `jsonwebtoken`, `reqwest-middleware`, and `anyhow`.

### Fixed
- **Auth**: Added `#[serde(default)]` to `UserRecord::disabled` to prevent deserialization errors when the field is missing from API responses.

## [0.2.2] - 2026-01-29

### Added
- **Documentation**: Added "Experimental" warning to README.
- **Testing**: Added comprehensive unit tests for Crashlytics, Remote Config, Auth, and Firestore modules.
- **Docs**: Converted documentation examples to `no_run` to ensure they compile and stay up-to-date.

## [0.2.1] - 2026-01-29

### Changed
- Bumped version to 0.2.1 to reflect experimental status update.

## [0.2.0] - 2026-01-18

  - Improved email action link generation (password reset, email verification, sign-in).
  - Multi-tenancy support via `TenantAwareness`.
- **Firestore**:
  - Implementation of `list_collections` for root and document levels.
  - Support for `WriteBatch` atomic operations.
  - Simplified Transaction API (removed lifetime requirements for easier async usage).
- **Storage**:
  - Implementation of V4 Signed URL generation.
  - Support for getting and setting/updating object metadata.
  - Comprehensive `Bucket` and `File` API for uploads, downloads, and deletions.
- **Crashlytics**: 
  - Implementation of the Firebase Crashlytics API for managing crash reports.
- **Core**:
  - Centralized `FirebaseErrorResponse` parsing for detailed API error messages.
  - `AuthMiddleware` refactor for efficient state sharing across services.

### Fixed
- FCM request serialization to use `camelCase` as required by the v1 API.
- Better error handling and reporting across all Firebase services.

### Testing
- Added comprehensive integration tests for Firestore Transactions, FCM Messaging, and Storage Signed URLs using `httpmock`.
