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 These are two distinct addresses — the seed wallet only signs the transaction and covers TON gas fees, while USDT is withdrawn from the Fragment-linked wallet.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

 ### 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

 - `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"]}`
