Version 1.5.0 (Stagenet)

Attention! This release is for stagenet only! Not for mainnet/testnet.

In this release

This release introduces the new Light Node operation mode which greatly reduces CPU usage during block processing, as well as lays the groundwork for the upcoming Waves 2.0 release. RocksDB is now used instead of LevelDB, and the storage structure has been updated to take advantage of RocksDB's improvements and optimizations.

Protocol Enhancements

• A block generator distributes state snapshots to the blockchain network, along with the key block and microblocks. Snapshots contain changes of blockchain state, including balances, entries of account data storages, assigned scripts, token parameters, etc., resulting from transactions added to the block. See the docs for more information about the Waves 1.5 protocol.
• If a generating node discovers a discrepancy between a received snapshot and a block, the node can challenge the block and receive a reward instead of the original generator.
• Other nodes get the option to operate in the light mode, sequentially applying ready-made state snapshots without performing transaction validation, and thus significantly speed up block processing. The light mode is enabled and disabled with the waves.enable-light-mode setting (no by default).
• Added to the block header:
  • state_hash field containing the root state hash for the block,
  • challenged_header message containing header fields of the block being challenged by the current block.
• Added the attachment field to an order as part of an Exchange transaction.

Ride

• Released version 8 of the Standard Library.
• Added built-in functions:
  • replaceByIndex — replaces an element in the list by index.
  • calculateDelay — calculates the time delay before generating a block.
• Added the attachment field to the Order structure.
• Disabled the ability to assign scripts, which use Standard Library versions 1-3, to accounts and assets. Previously installed scripts continue to operate.

Node REST API

• Added fields stateHash and challengedHeader to the response of endpoints returning a block or block header.

• Added fields order1.attachment and order2.attachment to the response of endpoints returning transactions, as part of an Exchange transaction.

• Added the value elided for the field applicationStatus for transactions of any type that have become invalid as a result of a block challenge.

• Removed deprecated API routes

  • /debug/stateChanges/address/{address}/limit/{limit}
  • /debug/stateChanges/info/{id}
  • /debug/rollback-to/{id}
  • /assets/broadcast/*
  • /assets/[transfer,masstransfer,…]

Version 1.4.18 (Mainnet + Testnet + Stagenet)

In this release

This is a mandatory release for all nodes. You need to update your Mainnet node before the new features are activated.

Protocol Enhancements

This release adjusts block reward distribution introduced with feature #​19 "Block Reward Distribution". The design of these features is based on the extensive feedback provided by the community members.

Feature #​20 "Capped XTN buy-back & DAO amounts".

The following changes will only take effect if feature #​19 has been activated.

• Waves DAO and XTN buy-back reward amounts are capped at 2 waves, e.g. if the community votes to increase block reward to 6.5 waves, block miners would receive 2.5 waves and Waves DAO and XTN buy-back addresses would receive 2 waves each.
• Block reward term is decreased from 100000 blocks to 50000 on Mainnet, Testnet and Stagenet. For custom networks, a new parameter term-after-capped-reward-feature has been added to Reward Settings.

Feature #​21 "Cease XTN buy-back"

Once activated, the XTN buy-back address will no longer receive its reward share, if feature #​19 had been activated more than X blocks ago (X is 100000 on Mainnet, 2000 on Testnet and 1000 on Stagenet). Waves DAO address would still receive at most 2 waves, with the rest of the reward going to the miner. This feature is meant to be a tool for the community to control the XTN buy-back mechanism.

REST API Changes

• A new field rewardShares has been added to block headers. The field contains a map of the addresses which received the reward share and its respective share amount.

Activation

Please vote for features #​19 and #​20 on Mainnet! The current voting window started at height 3670000. If the features are voted during this voting interval, activation will happen at height 3720000 (2023-07-06 18:14 UTC). Both features have been activated on both Testnet and Stagenet.

Update notes

There's no need to rebuild the state when upgrading from 1.4.16 or 1.4.17.

Version 1.4.16 (Mainnet + Testnet + Stagenet)

In this release

Protocol Enhancements

This release includes several consensus improvements implemented as hard forks which are bound to feature #​19 "Block Reward Distribution".

• With WEP-14 activation, block rewards would be shared between three beneficiaries: block miner, Waves DAO, and XTN buy-back contract. New RIDE stdlib version 7 adds the rewards field to BlockInfo structure. This field holds the list of tuples of beneficiary address and the amount they receive. Beneficiary addresses for Mainnet, Testnet and Stagenet are predefined in the functionality settings.
• Sync invoke action limit has been fixed to match the root contract version. After feature 19 activation, even if there is a V5 contract in invocation chain started by a V6 contract, V6 global limits will apply for the whole invocation chain.

Activation

To activate the improvements listed above, please vote for feature #​19 on Mainnet! The next activation window starts at height 3660001, which is expected to happen on 2023-05-26 at 05:00 UTC.

Version 1.4.14 (Mainnet + Testnet + Stagenet)

In this release

This is an optional release that includes numerous improvements and bug fixes.

• Added a new field to the asset details, which holds the sequence number of an asset within a block. This field (together with issue height) can be used to identify which of the two assets was issued earlier reliably. To take advantage of this new field, the blockchain needs to be re-imported. The new field is available in REST API, gRPC API and Blockchain Updates.
• Added new fields to BU events: VRF, features activated with the block, and script set by the transaction.
• Added support for mining with several addresses not derived from a single seed. If any base58-encoded private keys are specified in the waves.miner.private-keys setting, only those keys are used to sign blocks (wallet contents are ignored).
• Fixed an issue with script compaction, which incorrectly replaced references to global names in some cases.
• Fixed /utils/script/evaluate route to take payments attached to the transaction into the account when executing the call and to support Accept: application/json; large-significand-format=string header.
• Known transaction cache is reset on each microblock instead of each block, which will speed up transaction propagation.
• Fixed signal handling in docker container. Containers that were started in non-interactive mode (without -i flag) will cleanly shut down on Ctrl+C. This also allows capturing thread dumps by sending QUIT signal to a running container (docker kill -s QUIT $CONTAINER_ID).

Update notes

Unless you rely on asset ordering, there's no need to re-import blockchain when updating from 1.4.13.

Version 1.4.13 (Mainnet + Testnet + Stagenet)

In this release

This release brings MetaMask and other consensus fixes to Mainnet. After the activation of the feature #​18 all Protocol changes become available. This release is mandatory for all nodes: outdated nodes will shut down when new feature is activated, which is expected to happen on February, 18th, given sufficient miners support.

Protocol Enhancements

This release includes several consensus improvements implemented as hard forks which are bound to feature #​18 "Consensus and MetaMask improvements".

• Improved support for orders and transactions signed by MetaMask and by Ledger devices via MetaMask.
• Improved support for SetScript transactions containing longer scripts in RIDE.
• Genesis block signer will no longer get block reward even if feature #​18 is pre-activated.

Other Improvements

• Fixed NFT order in /assets/nft/{address}/limit/{limit}: the tokens are listed in the order they were received by the account, beginning with the most recent one. If you use your node to retrieve NFT list and rely on correct NFT order, you need to re-import blockchain for the fix to have effect.
• /utils/script/evaluate shows state changes when transaction-like invocation is evaluated. Also default complexity limit has been increased to 52000 to match invocation complexity limit.
• Added a new setting waves.utx.always-unlimited-execution. When enabled, all script invocations are evaluated completely, not up to the fail-free limit. This functionality is turned off by default.
• Misc improvements and optimisations in RIDE compiler.
• Added support for alternative commands in docker image, e.g.

  docker run -it wavesplatform/wavesnode:1.4.13 import -c /etc/waves/waves.conf -i https://blockchain.wavesnodes.com/mainnet_last
  

Activation

To activate the improvements listed above, please vote for feature #​18 on Mainnet!

Update notes

Unless you rely on proper NFT order described above, there's no need to re-import state when upgrading from 1.4.11.

Version 1.4.11 (Mainnet + Testnet + Stagenet)

In this release

This release improves node performance and prevents miners from generating empty blocks under heavy load. This release is strongly recommended for all node operators, especially miners.

InvokeScript transaction support in /utils/script/evaluate/{address}

This release adds support for evaluating transactions with /utils/script/evaluate/{address} endpoind. Transaction JSON can be specified in the request body. Neither proofs nor attached payments are validated; transaction sender, ID and other fields are retrieved from the supplied JSON. dApp field is ignored, the function is evaluated in the context of {address}. This functionality simplifies debugging contracts: no private key is required to simulate transaction processing.

RIDE compiler improvements

• Improved error messages make it easier to find out what's actually wrong with the code, and where exactly an error has occured.
• DApp meta is returned in JS and Java API.

Update notes

There's no need to re-import state when updating from 1.4.10.

Version 1.4.10 (Mainnet + Testnet + Stagenet)

In this release

This is a mandatory release which resolves an issue with transaction validation, as well as improves block processing performace for blocks containing excessive number of transactions.

An issue with docker containers introduced in 1.4.9 has also been fixed. There's no need to explicitly specify waves.directory in custom waves.conf unless you need to store data files in the non-default directory.

Update notes

There's no need to re-import blockchain when updating from v1.4.9.
