+## [2026.3.2] — 2026-06-16
+
+### 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.

+
+## Conventions
+
+- All public async methods live on `FragmentClient` and delegate to a domain service.
+- Domain functions receive a `FragmentClient` instance, never raw HTTP clients.
+- Patch targets in tests use the module where the name is **defined**, e.g. `pyfragment.services.tonapi.transaction._make_ton_client`.
+- Versioning follows [CalVer](https://calver.org/): `YYYY.MINOR.MICRO`. Bump in `pyproject.toml`; tag as `vYYYY.MINOR.MICRO`.
+
+## Pull requests
+
+- Keep PRs focused — one feature or fix per PR.
+- Update `CHANGELOG.md` under `[Unreleased]`.
+- Add or update tests for any changed behaviour.

-## Credentials
-
-**Fragment cookies** — log in to [fragment.com](https://fragment.com) and connect your TON wallet. You can get cookies in two ways:
-
-- **Automatically** (recommended) — use `get_cookies_from_browser()`, which reads them directly from your browser's on-disk store. No extension needed:
-  ```python
-  from pyfragment.utils import get_cookies_from_browser
-  result = get_cookies_from_browser("chrome")  # or "firefox", "edge", "brave", ...
-  # result.cookies — dict[str, str] to pass to FragmentClient
-  # result.expires — ISO 8601 expiry of stel_ssid, or None for session cookies
-  ```
-- **Manually** — install [Cookie Editor](https://chromewebstore.google.com/detail/cookie-editor/hlkenndednhfkekhgcdicdfddnkalmdm) and export these four keys: `stel_ssid`, `stel_dt`, `stel_token`, `stel_ton_token`. Pass them as a `dict` or JSON string.
-
-Refresh when you get authentication errors.
-
-**Tonapi key** — generate at [tonconsole.com](https://tonconsole.com).
-
-**Seed phrase** — 24-word mnemonic from your TON wallet (Tonkeeper → Settings → Backup). Never share it.

+- Affected versions.
+
+You will receive a response within 72 hours. Once the fix is released, the advisory will be published.
+
+## Scope
+
+This library handles sensitive credentials (GRAM (ex TON) seed phrases, Fragment session cookies, Tonapi keys). Please treat any finding that could expose or misuse these credentials as high severity.
