Version 1.2.16 (Mainnet + Testnet + Stagenet)

In this release

This is a mandatory release for all miners who have updated to 1.2.15. Unfortunately, a new feature has prematurely been added to implemented feature list.

Besides the fix, this release contains the following new features and improvements:

• New /utils/script/evaluate/{address} endpoint allows users to call any function declared in a dApp deployed to an {address}. This endpoint expects JSON input in the form of {"expr": "functionToCall(1, \"arg2\", base58\"AAA\")"}. Make sure to escape double quotes when passing a string as an argument.
• State changes for Invoke Script transactions will be included in JSON and gRPC responses of address transactions endpoint. /debug/stateChanges endpoint has been deprecated and will be removed in the future.
• Fixed error traces in API. Both /debug/validate and /transactions/broadcast will return detailed traces when transaction validation fails.
• The node will use native Curve25519 implementation on supported platforms, this will speedup signature verification.
• Improved Swagger schema and fixed several API routes to properly validate input parameters
• Improved UTX Priority Pool reliability

There's no need to rebuild state when updating from 1.2.14 or 1.2.15.

Version 1.2.15 (Mainnet + Testnet + Stagenet)

This release is broken. Please see v1.2.16 instead.

Version 1.2.14 (Mainnet + Testnet + Stagenet)

In this release

This release mostly brings improvements and bug fixes to Blockchain Updates and GRPC Server extensions, so if you are using either one — please consider upgrading. There's no need to rebuild state when updating from 1.2.12.

Here's the list of Blockhain Updates improvements:

• The extension has moved to GRPC Server extension distribution. It means that you'll need to install just one DEB package or tarball to use both (or either). When migrating from previous versions, please note that blockchain-updates config section has also moved to waves section. If you specified non-default listen port, please update your config accordingly.
• Fixed an issue which could cause REST API to become unresponsive when Blockchain Updates extension was enabled.
• Improved error messages when requests contained invalid data.

Other node improvements:

• GRPC Server now properly sets chain ID for blocks returned via GetBlock/GetBlockRange requests.
• Default JVM options in application.ini have been tweaked. When updating DEB package, dpkg may warn you that both locally installed and package-supplied files have changed. It's safe to keep your local version.
• Swagger documentation has been updated with improved request model definitions.
• Import from URL can now continue from where the process had been interrupted, so there's no need to re-download the import file fragment it has already processed.

Version 1.2.13 (Mainnet + Testnet + Stagenet)

In this release

• New Blockchain Updates extension is now a part of node release.
• /addresses/data/{address} method has been tweaked to run faster and consume less memory.
• Bloom filters are now disabled by default. This will make node start much faster after non-clean shutdown. Bloom filters will still be used during import.
• A new setting waves.utx.fast-lane-addresses allows miners to prioritize transactions from specific addresses.
• A new debug & monitoring API can be used to retrieve internal hashes of all state changes at specific height. These hashes can be used for early discrepancy detection between nodes.
• Instead of local time, miner will store calculated time in a block.

There's no need to rebuild state when upgrading from 1.2.12.

Version 1.2.12 (Mainnet + Testnet + Stagenet)

In this release

This release includes several REST API compatibility and stability improvements:

• Deprecated /assets/{assetId}/distribution method now returns all addresses holding an asset, not just the first 1000. However, please consider using a more reliable /assets/{assetId}/distribution/{height}/limit/{limit} method instead.
• The node will accept Burn transaction JSON with either quantity or amount field.
• Fixed several issues which caused the node to crash when requesting address transactions, state changes or portfolio for an address via REST API.

We encourage everyone using their node's REST API to update. There's no need to rebuild state when upgrading from 1.2.11.

Version 1.2.11 (Mainnet + Testnet + Stagenet)

In this release

• Restored (and deprecated; see below) the ability to use an empty string in transaction JSON's assetId and feeAssetId fields (where applicable). Please note that this change is introduced to restore compatibility with 1.1.x (and earlier). Future versions will only support null or non-empty base58-encoded asset IDs in these fields.
• Fixed a bug where responded with 200 and an empty response when a block could not be found for the valid block ID. This version will return 404 and BlockDoesNotExist error, just as expected.
• Fixed race condition in importer tool which could cause the final stage of the import process to corrupt the node's storage. If you are upgrading from 1.1.x and need to rebuild the state, it is once again safe to use importer tool.

There's no need to rebuild the state if you are updating from 1.2.10.

Version 1.2.10 (Mainnet + Testnet + Stagenet)

In this release

This release is accumulation of all previous 1.2.x releases. Now it's available for Mainnet.
After the activation of the feature #​15 all Protocol changes become available.

Below you can find the list of only major changes comparing to 1.1 release. The full list of changes can be found in the documentation.

Protocol changes

• Improved the mechanism for generating blocks by using VRF (Verifiable random function). This improvement allows withstanding stake grinding attacks, which are used by the attackers to try to increase the probability of generating a block for themselves.
• Implemented saving failed transactions. Invoke Script transactions and Exchange transactions are saved on the blockchain and a fee is charged for them even if the dApp script or the asset script failed, provided that the sender's signature or account script verification passed and the complexity of calculations performed during script invocation exceeded the threshold for saving failed transactions. More details
• Changed the scheme for signing the block transactions by the generating node. Previously, the generating node needed to sign the block header along with all transactions. For now, the transactions root hash is added to the header, so it is enough to sign only the header.
• Implemented binary transaction formats based on protobuf.
• Minimal interval between blocks is increased from 5 to 15 seconds. Average block time is targeted 60 seconds instead of current ~59 seconds.
• Implemented the feature of changing the asset name and description. For this means, the Update Asset Info transaction is used.
• Reduced the minimum fee from 1 to 0.001 WAVES for the Reissue transaction and Sponsor Fee transaction.
• Implemented the feature of deletion of entries from the account data storage. This action can be performed by the Data transaction or DeleteEntry structure of the Ride language.
• Changed the orders' price calculation formula. Earlier, when determining the price for assets with different numbers of decimal places, there was a price value size issue. The maximum value depended on the difference of decimal digits of assets. For example, the price for an NFT asset could not exceed 1000 WAVES. The modified formula corrects this problem. Decimal places no longer affect the maximum price.
• dApp can't call itself with InvokeScript transaction with attached payments. Also dApp can't transfer funds to itself by ScriptTransfer.

Ride improvements

• Issued version 4 of the Ride Standard library.
• Enabled processing up to two payments attached to the Invoke Script transaction (previously only one).
• Added script actions that the callable function of dApp can perform:
  • Token actions: Issue, Reissue, Burn, SponsorFee.
  • BooleanEntry, BinaryEntry, IntegerEntry, StringEntry that add or update the account data storage entries of the corresponding type. These actions replace DataEntry that is not supported in version 4.
  • DeleteEntry that deletes the account data storage entry.
• Changed the complexity of certain built-in functions and operators. Changes are listed in the Built-in Functions article.
• For the built-in hashing functions blakeb256, keccak256, sha256 and the built-in verification functions rsaVerify, sigVerify the complexity is changed in version 4 along with adding the range of similar functions with different complexity depending on the argument size limit.
• Added support of list of primitives as a callable function argument.
• Added built-in functions that verify the zero-knowledge proof zk-SNARK by groth16 protocol: groth16Verify (on the bls12-381 curve) and bn256groth16Verify (on the bn254 curve).
• Added the ecrecover built-in function that recovers public key from the message hash and the ECDSA digital signature.
• Added the following built-in functions and operators:
  • for lists operating: containsElement, indexOf, lastIndexOf, removeByIndex, min, max, median, ++ operator, :+ operator.
  • for strings operating: contains, makeString for concatenation.
  • valueOrElse(t: T|Unit, t0: T) that returns a value from the union type if it's not unit.
• Added the Tuple data type.
• Changed the maximum complexity to 2000 of an account script and verifier function of dApp script for new scripts, regardless of the Standard library version. The maximum complexity of an asset script and callable function of dApp script remains 4000.
• Changed the maximum data size:
  • String: 32,767 bytes
  • ByteVector: 32,767 bytes (except the bodyBytes field of the transaction structure).

REST API Updates

In the Node 1.2 release, we have some semantic and breaking changes in the API. Please read the following changes very attentively as it can affect your working application when migrating from Node 1.1 API to the Node 1.2 API.

Semantic

• As failed transactions can be saved in the blockchain so it's not enough to see presence of Invoke Script and Exchange transactions in the blockchain - user needs to check their status. Please see new field "applicationStatus" in methods listed in the full release notes.
• In the stateChanges of invoke Script transaction user now can find the reason of failure if transaction is failed in the "error" field in the following methods:
  • /debug/stateChanges/address/{address}/limit/{limit}
  • /debug/stateChanges/info/{id}
• There are new fields for stateChanges of Invoke Script transaction due to new script actions. Now it has the following structure: "stateChanges": { "data": [], "transfers": [], "issues": [], "reissues": [], "burns": [], "sponsorFees": [], "error": {"code": number, "text": string} }
  Affected methods:
  • /debug/stateChanges/address/{address}/limit/{limit}
  • /debug/stateChanges/info/{id}
• "reference" field in Block v5 corresponds to "id" of the previous block instead of "signature" in Block v4.

Breaking changes

• Blocks now get by their id instead of signature. Affected methods:
  • /blocks/delay/{id}/{blockNum}
  • /blocks/height/{id}
  • /block/signature
  • /debug/rollback-to/{id}
  • /blocks/child
• Method /consensus/generationsignature deleted.
• In /addresses/scriptInfo/{address}/meta agrument list is now listed as an object array.
  Before: "meta": { "callableFuncTypes": { "funcName": { "arg1": string, "arg2": string } } }
  Now: "meta": { "callableFuncTypes": { "funcName": [ { "name": string, "type": string }, { "name": string, "type": string } ] } }
• There is new transaction Update Asset Info.
• Invoke Script transaction now can have arguments of List type: { "call": { "function": string, "args": [ ["arg1-item1", "arg1-item2", "arg1-item3"] ] } }
• Data in accoun...

Version 1.2.9 (Stagenet)

In this release

Node

• Fixed account data by regex API
• /transactions/broadcast always validates Invokes and Exchanges, and discards if it's failed
• Changes in UTX synchronizer/cleanup behaviour with "failed" transactions
• Exchange matcher fee asset scripts don't count in block complexity and tx min fee requirement
• Custom min block interval for custom blockchains
• /debug/validate route made public, now works correctly with scripted Exchange transactions
• Some minor protobuf, REST API, importer fixes

RIDE Changes

• Free complexity limit (which will prevent some InvokeScript transactions from being failed) has been decreased to 1000.
• Minor improvements and bug fixes

Update Notes
