+## [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.
+
+---
+
+## [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)
+
+---
+
+## [2026.1.0] — 2026-03-25
+
+### Added
+
+**Giveaways**
+
+- `giveaway_stars(channel, winners, amount)` — Stars giveaway; 1–5 winners, 500–1 000 000 stars each
+- `giveaway_premium(channel, winners, months)` — Premium giveaway; 1–24 000 winners, 3/6/12 months each
+- `StarsGiveawayResult`, `PremiumGiveawayResult` result types
+
+**Telegram Ads**
+
+- `recharge_ads(account, amount)` — top up a Telegram Ads account; 1–1 000 000 000 TON
+- `AdsRechargeResult` result type
+
+**Marketplace**
+
+- `search_usernames(query?, sort?, filter?, offset_id?)` — search Fragment usernames; `sort`: `price_desc / price_asc / listed / ending`, `filter`: `auction / sale / sold`
+- `search_numbers(query?, sort?, filter?, offset_id?)` — search Fragment anonymous numbers; same `sort` / `filter` / pagination semantics
+- `search_gifts(query?, collection?, sort?, filter?, view?, attr?, offset?)` — search Fragment gifts; `attr` accepts `{"Model": ["Foosball"], "Backdrop": ["Celtic Blue"]}`
+- `UsernamesResult`, `NumbersResult`, `GiftsResult` result types
+
+**Anonymous numbers**
+
+- `get_login_code(number)` — fetch the current pending login code
+- `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)
+- `examples/auctions/` — `search_usernames.py`, `search_numbers.py`, `search_gifts.py` (marketplace search with pagination)
+- `examples/purchase/` — `send_stars.py`, `send_premium.py`, `topup_ton_balance.py`, `run_stars_giveaway.py`, `run_premium_giveaway.py`, `recharge_ads_balance.py`
+
+### Changed
+
+- All result types now expose a unified `amount` field (`months` and `stars` removed)
+- `__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
 - README usage section rewritten with a single comprehensive `async with` example

+## 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.
