 ---
 
+## [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 These are two distinct addresses — the seed wallet only signs the transaction and covers TON gas fees, while USDT is withdrawn from the Fragment-linked wallet.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.utils 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

 - `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

 ## [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
 
 ### Fixed

 - mypy: `cookies` union-attr error in `FragmentClient.__init__`
