TON v2024.01

2024.01 Update

1. Fixes in how gas in transactions on special accounts is accounted in block limit. Previously, gas was counted as usual, so to conduct elections that costs >30m gas block limit in masterchain was set to 37m gas. To lower the limit for safety reasons it is proposed to caunt gas on special accounts separately. Besides gas_max is set to special_gas_limit for all types of transactions on special accounts. New behavior is activated through setting version >= 5 in ConfigParam 8;.
   • Besides update of config temporally increases gas limit on EQD_v9j1rlsuHHw2FIhcsCFFSD367ldfDdCKcsNmNpIRzUlu to special_gas_limit, see details.
2. Improvements in LS behavior
   • Improved detection of the state with all shards applied to decrease rate of Block is not applied error
   • Better error logs: block not in db and block is not applied separation
   • Fix error in proof generation for blocks after merge
   • Fix most of block is not applied issues related to sending too recent block in Proofs
   • LS now check external messages till accept_message (set_gas).
3. Improvements in DHT work and storage, CellDb, config.json ammendment, peer misbehavior detection, validator session stats collection, emulator.
4. Change in CTOS and XLOAD behavior activated through setting version >= 5 in ConfigParam 8;:
   • Loading "nested libraries" (i.e. a library cell that points to another library cell) throws an exception.
   • Loading a library consumes gas for cell load only once (for the library cell), not twice (both for the library cell and the cell in the library).
   • XLOAD now works differently. When it takes a library cell, it returns the cell that it points to. This allows loading "nested libraries", if needed.

Besides the work of the Core team, this update is based on the efforts of @XaBbl4 (peer misbehavior detection) and @akifoq (CTOS behavior and gas limit scheme for special accounts).

TON v2023.12

1. Optimized message queue handling, now queue cleaning speed doesn't depend on total queue size
   • Cleaning delivered messages using lt augmentation instead of random search / consequtive walk
   • Keeping root cell of queue message in memory until outdated (caching)
2. Changes to block collation/validation limits
3. Stop accepting new external message if message queue is overloaded
4. Introducing conditions for shard split/merge based on queue size

Read more on that update.

TON v2023.11

2023.11 Update

1. New TVM Functionality. (Disabled by default)
2. A series of emulator improvements: libraries support, higher max stack size, etc
3. A series of tonlib and tonlib-cli improvements: wallet-v4 support, getconfig, showtransactions, etc
4. Changes to public libraries: now contract can not publish more than 256 libraries (config parameter) and contracts can not be deployed with public libraries in initstate (instead contracts need explicitly publish all libraries)
5. Changes to storage due payment: now due payment is collected in Storage Phase, however for bouncable messages fee amount can not exceed balance of account prior to message.

Besides the work of the core team, this update is based on the efforts of @aleksej-paschenko (emulator improvements), @akifoq (security improvements), Trail of Bits auditor as well as all participants of TEP-88 discussion.

Besides the work of the core team, this update is based on the efforts of @aleksej-paschenko (portability improvement), Disintar team (archive manager optimization) and sec3-service security auditors (funC improvements).

TON 2023.04 and FunC 0.4.3

2023.04 Update

1. CPU load optimization: previous DHT reconnect policy was too aggressive
2. Network throughput improvements: granular control on external message broadcast, optimize celldb GC, adjust state serialization and block downloading timings, rldp2 for states and archives
3. Update for Fift (namespaces) and Fift libraries (list of improvements: #631)
4. Better handling of incorrect inputs in funC: fix UB and prevent crashes on some inputs, improve optimizing int consts and unused variables in FunC, fix analyzing repeat loop. FunC version is increase to 0.4.3.
5. listBlockTransactionsExt in liteserver added
6. Tvm emulator improvements

Besides the work of the core team, this update is based on the efforts of @krigga (tvm emulator improvement), @ex3ndr (PUSHSLICE fift-asm improvement) and sec3-service security auditors (funC improvements).

TON 2023.03 and FunC 0.4.2

03.2023 Update

1. Improvement of ADNL connection stability
2. Transaction emulator support and getAccountStateByTransaction method

5. FunC Mathlib

TON 2023.01 and FunC 0.4.1

1. Added ConfigParam 44: SuspendedAddressList. Upon being set this config suspends initialisation of uninit addresses from the list for given time.
2. FunC: v0.4.1 added pragmas for precise control of computation order
3. FunC: fixed compiler crashes for some exotic inputs
4. FunC: added legacy tester, a collection of smart-contracts which is used to check whether compilator update change compilation result
5. Improved archive manager: proper handling of recently garbage-collected blocks

TON 2022.12 and FunC 0.4.0

Node update:

1. Improvements of ton-proxy: fixed few bugs, improved stability
2. Improved collator/validator checks, added optimization of storage stat calculation, generation and validation of new blocks is made safer
3. Some previously hard-coded parameters such as split/merge timings, max sizes and depths of internal and external messages, and others now can be updated by validators through setting ConfigParams. Max contract size added to configs.
4. Tonlib: updated raw.getTransactions (now it contains InitState), fixed long bytestrings truncation
5. abseil-cpp is updated to newer versions
6. Added configs for Token Bridge
7. LiteServers: a few bug fixes, added liteServer.getAccountStatePrunned method, improved work with not yet applied blocks.
