Version 1.2.2 (Stagenet)

In this release

This is a maintenance release which changes the way VRF is used in block consensus validation. The changes it introduces are not compatible with previous 1.2.x releases, so the blockchain has been rolled back to height 264700. You will also need to re-import blockchain when updating your node.

Other notable changes:

• For v5 blocks VRF is now accessible in RIDE's BlockInfo structure, as well as in REST API
• Order v4 price calculation rules have changed

Version 1.1.7 (Mainnet + Testnet)

In this release

This release contains an important fix and is highly recommended for all miners and those who broadcast transactions via their node's REST API. However, it does not contain any consensus changes, so it is not required to update your node. There's no need to rebuild state when upgrading from 1.x.

UTX Synchronization Fix

This release fixes an issue with unconfirmed transaction synchronizer, which sometimes caused the node not to include any transactions or include little amount of transactions in the blocks it forges. Most of the recent empty blocks on the blockchain were caused by this issue.

REST API Improvements

• the above issue also caused sporadic "Error is unknown" errors when broadcasting transactions via REST API. Since the root issue has been fixed, transaction broadcast reliability should improve
• Swagger documentation for /transactions/status method has been fixed, which makes it usable via the web interface.

Version 1.2.1 (Stagenet)

Note. This release is for Stagenet only

In this release

This release contains several important improvements:

• Fixed microblock exchange between peers.
• Custom networks launching with pre-activated BlockV5 feature no longer stall after the first block had been generated.
• Fixed script and function call serialization in new transactions.

Due to changes in InvokeScriptTransaction serialization, stagenet blockchain has been reset to height 245781. Please re-import blockchain from file.

Version 1.1.6 (Mainnet + Testnet)

In this release

This is a mandatory release, as it contains several security fixes, as well as other improvements. However, there's no need to rebuild state when upgrading from 1.x.

UTX Pool Improvements

• Invoke script transactions count towards size limit. waves.utx.max-scripted-size is set to 5000 by default.
• To reduce the amount of logs the node produces under heavy load, execution traces are no longer written to waves.log by default. If you need the traces, define logback.utx-trace.enabled system property either in application.ini, on the command line or in logback.xml to save traces to utx-trace.log. Also waves.log is now rotated when size limit is reached (100 mb by default), in addition to daily rotation.
• When microblock is appended, transactions it contains are removed from pessimistic portfolio.

Miner Improvements

• To improve mining performance, the miner packs unconfirmed transactions in several passes. This ensures that non-scripted transactions are included in the microblock even when scripted transactions pool size limit is reached.
• Default waves.miner.min-micro-block-age has been reduced from 6 seconds to 4 seconds. This will likely reduce the number of orphaned transactions during microforks.

API Changes

• New API has been added which allows requesting transaction statuses in batches. It supports both GET and POST methods:

  GET /transactions/status?id=3qsBVPVRzyfityEo4cpL6ZyAZdXyJ5YQfR2vSeRbvxNy&id=CyvroiVc46ekEtVksmWndS99QSgddMEJozArXEHqKP5r
  POST /transactions/status {"ids": ["3qsBVPVRzyfityEo4cpL6ZyAZdXyJ5YQfR2vSeRbvxNy", "CyvroiVc46ekEtVksmWndS99QSgddMEJozArXEHqKP5r"]

See documentation for more info.

• The node can now render numbers which can potentially have large significand (e.g. balances, amounts, quantites etc.) as strings. To request custom JSON serialization, clients must include the following header in their requests:

  Accept: application/json;large-significand-format=string

See documentation for more info.

• Transactions for address from liquid block are returned in the same order as they were mined.
• Fix callable functions arguments types fetching via /addresses/scriptInfo/{address}/meta.
• Fix decompilation of native function names.
• Add optional receiving of script result trace on transaction broadcast by specifying additional trace=yes parameter.
• Fixed an issue where the node API returned incorrect generating balance

Misc Improvements

• Importer/Exporter shut down gracefully even when metrics are enabled
• Reduced systemd stop timeout
• Improved locking mechanism

Version 1.2.0 (Stagenet)

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

In this release

Node improvements

• Improved block generation signature by implementing VRF (A Verifiable Random Function with Short Proofs and Keys). VRF is a pseudo-random function that uses a message and the private key of an account to provide a non-interactively verifiable proof for the correctness of its output. The use of VRF makes signature generation unpredictable because of the need to know the private key for calculation.
• Added MerkleRootHash of block's transactions to the header, so that now it is sufficient to sign only the block header. Earlier, the miner node signed each block's transactions and its header. Read more about block generation.
• Implemented account data storage records deletion by data transaction.
• Implemented update asset info transaction. Now users can update names and descriptions of their issued assets.
• Reduced the minimum transaction fee for reissue transaction from 1 to 0.001 WAVES.

Internal storage structure has changed in this release. You will need to rebuild the state.

REST API updates

• GET /assets/details/{assetId} returns issued/reissued/burnt asset details. This endpoint also accepts multiple asset IDs.
• GET /assets/nft/{address}/limit/{limit} returns assetDetails array of NFT assets which belong to address.
• GET /transactions/merkleProof?id=some1&id=some2 returns merkle proofs for requested transactions.

Ride improvements

• Issued fourth version of the Ride standard library.
• Added built-in math median function. The function calculates the median of a list of integers.
• Added DeleteEntry structure for implementing the deletion of records in the account data storage.
• Implemented feature of using of issue, reissue and burn transactions in dApps.
• Divided DataEntry structure on following structures:
  • BinaryEntry structure. The structure implements a binary data record of the account data storage.
  • BooleanEntry structure. The structure implements a boolean data record of the account data storage.
  • IntegerEntry structure. The structure implements an integer data record of the account data storage.
  • StringEntry structure. The structure implements a string data record of the account data storage.
• Implemented processing in dApp up to two payments attached to invoke script transaction.
• Added built-in zero-knowledge proof verifier function groth16verify
• Added convenient option value handling function valueOrElse

Version 1.1.5 (Mainnet + Testnet + Stagenet)

Security Fix

This release contains a security fix which has been released with version 1.1.4. The only difference is that this release is built from github sources after the fix had been published. If you have already updated to 1.1.4, you can skip this release. However, if you have not updated yet, make sure to update both the node and gRPC server extension to 1.1.5.

An issue in gRPC server extension allowed signing transactions with node's private key via gRPC without requiring API key (or any other authentication token). This issue only affects the nodes which expose gRPC interface to a third party (by default, the server binds to local address only). The method has been disabled in the extension, it will respond with NOT_IMPLEMENTED to all requests. We might re-enable this method when we find a viable gRPC equivalent of an API key.

Node Improvements

• Improved /addresses/data/{address} now accepts the list of keys to retrieve values for. These keys can be specified as:
  • repeated query params in a GET request: key=first_key&key=second_key
  • JSON object with the keys field in a POST body: {"keys": ["first_key", "second_key"]}
  • multipart/form-data or application/x-www-form-urlencoded in a POST body.
    Please note that appropriate content types and param encoding is required.
• A hard time limit has been imposed on UTX transaction validation duration. All transactions which are received from network or API and take longer than 5 seconds to validate are rejected. This rule is not a part of consensus and only affects unconfirmed transactions.
• NFT list API endpoint has been fixed to return only tokens which are currently in posession of the specified address
• Smart contract execution has been sped up thanks to Waves context reuse
• gRPC Server can now be built on Windows hosts
• Posting account data via /addresses/data has been deprecated and will be removed in one of the future releases. Please explicitly broadcast signed Data Transactions by POSTing to /transactions/broadcast instead.

Update Notes

If you are running version 1.1.4, you may skip this release, because it has been built from the same source. Also there's no need to rebuild state if you are updating from 1.1.3. Please make sure to update both the node and gRPC server extension.

Version 1.1.4 (Mainnet + Testnet + Stagenet)

This release has been superseded by v1.1.5

Node Improvements

• Improved /addresses/data/{address} now accepts the list of keys to retrieve values for. These keys can be specified as:
  • repeated query params in a GET request: key=first_key&key=second_key

• gRPC Server can now be built on Windows hosts
• Posting account data via /addresses/data has been deprecated and will be removed in one of the future releases. Please explicitly broadcast signed Data Transactions by POSTing to /transactions/broadcast instead.

Security Fix

This release fixes a security issue. If you have gRPC Server extension installed, please make sure to update it along with the node.

To avoid premature disclosure and allow some time for node owners to update, we will publish the fix to github on Monday, October 28 at 13:00 UTC. Binaries for this release were built from our private repo.

Update: the fix has been published and released as v1.1.5

Update Notes

There's no need to rebuild state if you are updating from 1.1.3.

Version 1.1.3 (Mainnet + Testnet + Stagenet)

This is an optional release, however, we encourage all miners to update their nodes to improve miner performance.

In This Release

• Reduced the amount of empty blocks.
  Miner will continue mining microblocks even when UTX pool temporarily becomes empty after all transactions had been removed due to validation errors.
• All DB-related errors are treated as fatal and cause the node process to be terminated (see below).
• Fixed an issue when Explorer, Importer and Exporter never exited when metrics were enabled.

Known Issues

In some cases DB-related errors (e.g. writes failures caused by the lack of free space) were silently discarded by prior node versions, which made it appear as though the node has forked from the rest of the network for no apparent reason. This release introduces some additional tweaks to make these errors more apparent. If your node stops with exit code 74, please file a bug.

Update Notes

There's no need to rebuild state if you are updating from 1.1.2.

Version 1.1.2 (Mainnet + Testnet + Stagenet)

In This Release

Stagenet

In order to test new functionality without affecting projects on the testnet we represent new blockchain — stagenet. The testnet from now on becomes stable. The Waves testnet and mainnet will have the same versions and will be updated simultaneously. There is a separate .deb file for the stagenet in the release artifacts.

Please join the stagenet as a miner!

WEP 4: Block Reward and Community Driven Monetary Policy

Generators will receive additional WAVES with each generated block. The amount of the reward will be regulated by miners’ voting. WEP 4 is published here.

BlockReward is implemented as Feature 14. Please vote!

RIDE improvements

• Fixed complexity estimator returning incorrect values in some cases
• Decompiler improvements
• Callable function signatures exposed via REST API at /utils/script/meta and /addresses/scriptInfo/{address}/meta.

Node updates

• Protobuf schemas have moved to a dedicated repository, which also includes instructions on how to add them to your project. This release also includes numerous fixes and improvements in gRPC server extension.
• Added support for Java 11.
• As long as there are no established connections to other peers, the node will more aggressively attempt to establish a new connection, which should improve the startup process.
• When DEB package is reinstalled during updates, the Node process will be restarted automatically.
• The node will stop on a disk-related exception (e.g. when there's no space left on the device)
• Due to scheduling issues, previous node versions could mine microblocks less often than specified in miner config. This is no longer the case: this version improves mining accuracy ensuring that microblocks are mined as often as specified.

REST API changes

• API key which was previously used for all networks by default has been removed from default configuration files and banned from use. If you rely on API key protected methods, read the docs to find out how to adjust your node's configuration.
• /assets/broadcast/* routes have been removed for good. They have been hidden from Swagger for a long time, and now their time has come. Please use /transactions/broadcast instead.

Update Notes

There's no need to rebuild state when updating from v1.0.2.

Docker image

From now on, node releases will be published to Docker Hub. Read more about running a container here.

APT repository

We are now providing an APT repository to make it easier for node operators to install and update their deployments. The repo provides mainnet, testnet and stagenet packages. To install the latest version of a package for mainnet from the repo, run the following commands:

curl -sL http://apt.wavesplatform.com/apt-key.gpg | sudo apt-key add -
add-apt-repository "deb https://apt.wavesplatform.com/ xenial mainnet"
apt update
apt install waves

Note: don't worry about the 'xenial' part in the repo name: Waves package should work on Debian jessie+, Ubuntu xenial+, and their forks.
Note: If this is a fresh install, APT will also pull all required dependencies (namely OpenJDK 8). Once the new version is released, you can easily update the package:

apt update 
apt upgrade
