## [2026.3.2] — Unreleased

### Added

- Added `ApiProvider` enum with `TONAPI` (tonconsole.com, default) and `TONCENTER` (t.me/toncenter) values.
- Added `api_provider` parameter to `FragmentClient` — select the blockchain API provider at init time (`"tonapi"` or `"toncenter"`).
- Both providers accept `api_key` with the same interface; the correct `tonutils` client is selected automatically.

- New `AlreadySubscribedError` exception for Premium purchase flows when Fragment returns: `This account is already subscribed to Telegram Premium.`
- New `UserNotFoundError.NOT_A_USER` message for when Fragment returns: `Please enter a username assigned to a user.` (e.g. when the username belongs to a channel or bot).
- Added `WalletVersion.HighloadV2` and `WalletVersion.HighloadV3R1` to `WalletVersion`

### Changed

- Updated purchase and giveaway flow state nonces (`dh`) to use nonce-like dynamic values with a wider integer range.
- Stars and Premium giveaway flows now include explicit price update steps before init requests:
  - `updateStarsGiveawayPrices`
  - `updatePremiumGiveawayPrices`
- Updated `DEVICE_INFO` fingerprint: Tonkeeper `appVersion` -> `26.05.0`.
- Updated client docstrings and purchase examples to document all supported payment methods.

### Renamed — TON -> GRAM (ex TON)

The TON blockchain has been rebranded to **GRAM (ex TON)**. All identifiers, messages, and documentation have been updated accordingly.

**Public API**

- `FragmentClient.topup_ton()` → `topup_gram()`
- `PaymentMethod.TON` → `PaymentMethod.GRAM`
- `PaymentMethod.USDT_TON` → `PaymentMethod.USDT_GRAM`
- `WalletInfo.ton_balance` → `WalletInfo.gram_balance`

**Constants**

- `TON_TOPUP_MIN` / `TON_TOPUP_MAX` → `GRAM_TOPUP_MIN` / `GRAM_TOPUP_MAX`
- `MIN_TON_BALANCE` → `MIN_GRAM_BALANCE`
- `USDT_TON_MASTER_ADDRESS` → `USDT_GRAM_MASTER_ADDRESS`

**Exceptions**

- `ConfigurationError.INVALID_TON_AMOUNT` → `INVALID_GRAM_AMOUNT`
- `WalletError.LOW_TON_BALANCE` → `LOW_GRAM_BALANCE`
- `WalletError.TON_BALANCE_CHECK_FAILED` → `GRAM_BALANCE_CHECK_FAILED`

**Internals**

- `pyfragment/core/constants/ton.py` → `gram.py`
- `check_ton_payment_balance()` → `check_gram_payment_balance()`

## [2026.3.1] — 2026-05-29

### Added

- Python 3.13 and 3.14 are now officially supported and included in the CI test matrix and PyPI classifiers.
- `WalletVersion` is now exported from the top-level `pyfragment` package.

### Changed

- `process_transaction` (internal) refactored into focused subfunctions: `_extract_message`, `_check_payment_balances`, `_broadcast_with_retry`.
- `raw_api_call()` moved from `FragmentClient` into `pyfragment.domains.base` and exposed as a standalone helper.
- `tonapi` domain internal helpers removed from public `__init__.py` exports; only `TonapiService` is exported.
- README rewritten with badges, structured sections, and complete usage examples.
- Added `CONTRIBUTING.md` and `SECURITY.md`.

### Fixed

- CI: `mypy` now runs with `--explicit-package-bases` to avoid false-positive import errors.
- CI: `pip` dependency cache enabled to speed up workflow runs.
- CI: `warn_unused_ignores` suppressed for `pyfragment.core.cookies` to handle the optional `rookiepy` dependency correctly across environments where the package may or may not be installed.
- Publish workflow now uses `generate_release_notes: true` instead of manual changelog extraction.

### Removed

- `tonapi/transfer.py` and associated `TonTransferResult` / `UsdtTransferResult` models (internal, unused).

---

## [2026.3.0] — 2026-05-21

### Changed

- Internal architecture reorganized around explicit domain packages:
  - TON account and balance helpers are now unified under `pyfragment.domains.tonapi.account`
  - service wrappers and operation modules are aligned by domain (`ads`, `purchases`, `giveaways`, `anonymous_numbers`, `marketplace`, `tonapi`)
- Package exports were cleaned up for domain and model packages (`__init__.py`) to provide clearer public symbols.
- Examples and system tests were updated to follow current public import paths and project structure.

### Fixed

- `get_cookies_from_browser()` is now patch-friendly in tests (`pyfragment.core.cookies.rookiepy` can be mocked reliably).
- Anonymous number `NOT_OWNED` error message wording was adjusted for test and backward-compatibility with existing matchers.

## [2026.2.3] — 2026-05-12

### Fixed

- Fixed USDT payment flow: the USDT balance check now correctly targets the wallet linked to the Fragment account (`transaction["from"]`), not the signing seed wallet. These are two distinct addresses — the seed wallet only signs the transaction and covers TON gas fees, while USDT is withdrawn from the Fragment-linked wallet.
- Fixed `clean_decode()` incorrectly treating binary TON cell payloads (e.g. jetton transfer messages with non-zero op codes) as text comments. Only cells with op code `0x00000000` are now decoded as snake-encoded UTF-8 strings; all other op codes return the raw `Cell` as-is.
- Restored and correctly wired USDT balance validation so `WalletError` is raised before broadcasting when the Fragment-linked wallet has insufficient USDT.

### Note

- USDT (`usdt_ton`) payments require USDT to be held in the TON wallet that is linked to your Fragment account profile. The seed wallet configured in `FragmentClient` is only used to sign transactions and pay TON network fees.

## [2026.2.2] — 2026-05-11

### Added

- `payment_method` option (`"ton"` / `"usdt_ton"`) for:
  - `purchase_stars()`
  - `purchase_premium()`
  - `giveaway_stars()`
  - `giveaway_premium()`

### Changed

- Added runtime validation for `payment_method` via `SUPPORTED_PAYMENT_METHODS` and `ConfigurationError.INVALID_PAYMENT_METHOD`
- Updated method docstrings to explicitly document recipient/channel formats:
  - `@username` / `username` / `https://t.me/username`
- `get_wallet()` now returns balances as separate fields: `ton_balance` and `usdt_balance`
- Wallet/system test output now prints TON and USDT balances on separate lines
- Balance checks are now method-aware with explicit thresholds:
  - `ton`: minimum TON balance threshold via `MIN_TON_BALANCE` (based on current 50 Stars purchase amount)
  - `usdt_ton`: minimum USDT balance threshold via `MIN_USDT_BALANCE` (based on current 50 Stars purchase amount)

### Tests

- Extended stars and premium test suites to cover:
  - invalid payment method
  - payment method propagation to `init*Request` payloads
  - accepted query formats (`@`, plain username, `t.me` link)
- Extended wallet tests to verify separate TON/USDT balance values in `WalletInfo`

### Documentation

- Simplified `README` usage example

## [2026.2.1] — 2026-05-03

### Fixed

- Fragment API 429 responses are now retried automatically (up to 3 attempts) with exponential backoff and jitter in `fragment_request`
- Retry delays in TON transaction broadcasting now include jitter to reduce contention under concurrent calls
- Improved handling of non-200 HTTP responses in `get_fragment_hash`
- Removed unnecessary `method` key leaking into certain API request payloads

### Changed

- Type hints refined across the codebase for better clarity and `mypy` strict compliance

---

## [2026.2.0] — 2026-04-14

### Added

- `get_cookies_from_browser(browser)` — extract Fragment session cookies directly from an installed browser (Chrome, Firefox, Edge, Brave, Arc, Opera, Safari, and more); no browser extension or manual copy-paste required
  ```python
  from pyfragment import get_cookies_from_browser
  result = get_cookies_from_browser("chrome")  # or "firefox", "edge", "brave", ...
  client = FragmentClient(seed="...", api_key="...", cookies=result.cookies)
  print(result.expires)  # ISO 8601 expiry of stel_ssid, or None for session cookies
  ```
- `CookieResult` — return type of `get_cookies_from_browser()`; exposes `.cookies` (`dict[str, str]`) and `.expires` (ISO 8601 string or `None`)

### Changed

- `DEVICE` Tonkeeper fingerprint updated: `appVersion` → `26.04.0`
- `tonutils` upgraded to **2.1.0**
- Minimum Python version lowered to **3.10** (previously 3.12)

- `toggle_login_codes(number, can_receive)` — enable or disable login code delivery
- `terminate_sessions(number)` — terminate all active Telegram sessions (two-step flow handled internally)
- `LoginCodeResult`, `TerminateSessionsResult` result types; `AnonymousNumberError` exception

**Raw API**

- `FragmentClient.call(method, data, *, page_url)` — raw request to any Fragment API method
- `FRAGMENT_BASE_URL` constant — base URL shared across all page constants and headers

**Examples**

- `examples/client/` — `wallet_info.py` (wallet info), `raw_api_call.py` (raw API call)
- `examples/numbers/` — `manage_number.py` (login code fetch, session termination)

- `__repr__` includes the unit — `3 months`, `500 stars`, etc.
- `timestamp` removed from all result dataclasses
- All page URL constants built from `FRAGMENT_BASE_URL`;
- `TransactionError` includes an SSL hint; `DUPLICATE_SEQNO` variant auto-retried up to 2 times (2 s apart)
- Error messages rewritten: "what happened → why → what to do"

---

## [2026.0.2] — 2026-03-20

### Added

- `timeout` parameter on `FragmentClient` (default `30.0` s) — passed through to every HTTP request

### Changed

- Cookie validation: narrowed type internally so no `# type: ignore` is needed in `FragmentClient.__init__`
- `WALLET_CLASSES` typed as `dict[str, Any]` so mypy resolves `from_mnemonic` correctly
- All four `examples/` files updated to `async with FragmentClient`, f-strings, and aligned error messages
