v1.3.3

Notice: Still don't forget that full resynchronization is required if upgrading from versions earlier than v1.3.0.

This is a maintenance release.

Changes:

• for customnet: accept bigint in hexadecimal string
• fix a minor bug that in rare cases the master node will ignore better block when receives two or more blocks with the same number almost at the same time
• improve solo in on-demand mode
• allow to query pending tx via GET /transactions/{id}?pending=true
• bump API version to 1.3.2

v1.3.2

Notice: Still don't forget that full resynchronization is required if upgrading from versions earlier than v1.3.0.

This release mainly enhances the API GET /blocks/{rev} by introducing the query option expanded, which allows querying detailed blocks with transactions and receipts embedded.

Additionally, the gas-limit-oracle algorithm is improved.

Get expanded block example

curl http://localhost:8669/blocks/5362401?expanded=true

gives

  "number": 5362401,

v1.3.1

Notice: Don't forget that full resynchronization is required if upgrading from versions earlier than v1.3.0.

This is a maintenance release, which includes performance improvements:

• Upgrade leveldb to avoid getting stuck under heavy workload
• Adjust leveldb options to reduce the number of table files

Entropy (v1.3.0)

IMPORTANT HINT: full resynchronization is required when upgrading to this release.

After months of work, now comes the most significant update since mainnet launch. This release brings many dramatic improvements, especially in terms of performance and efficiency:

• Drastically reduces disk space occupation by 80% (with state pruner enabled)
• At least 2X as fast to access cold VM state
• Much more effective trie cache, reduces 50% RAM usage
• Greatly speeds up querying event/transfer logs
• Reduces logdb size by 40%

Notable changes:

• Fix improper connection limit setting for logdb
• Remove live blocklist
• Fully rebuild maindb
  • save trie nodes with node-path as prefix
  • use freecache to replace bigcache
  • optimize trie cache
  • support pruning trie nodes
  • use trie to index blocks and transactions
  • store one tx/receipt per record instead of bundle
  • optimize tx/receipt cache
  • support querying block number by timestamp
• Improve VM state error handling
• Redesign logdb table schemas
  • add ref table to map id and data to reduce disk space usage
  • optimize indexes to cover most cases
  • remove time range query options
• Improve gas limit suggestion algorithm
• Optimize block packing process
• Reset default cache flag value to 1GB
• Add the feature of adaptive gas limit for solo mode
• Add cache option for solo mode
• Deprecated APIs removed:
  • POST /logs/events
  • POST /logs/transfers
  • POST /events
  • POST /transfers

v1.2.0

With the consensus of the first all-stakeholder voting, this release will activate the fork BLOCKLIST on Mainnet, at block # 4,817,300(~ Fri, 10 Jan 2020 5:40 GMT). All nodes are required to be upgraded ASAP.

v1.1.5

This is a maintenance release, which contains performance improvement and bug fixes.

• Adjustment to cache limit size.
• Fix incorrect result in querying event logs with multi criteria.
• Cache candidate list to speed up PoA process.
• Cache code bitmap to speed up contract call.
• Upgrade leveldb version.
• Update boot node list.
• Amendments to txpool to add a blocklist.

v1.1.4

This is a maintenance release, which contains performance improvement and bug fixes.

• Fix(api): expose non-standard response headers
• Limit maximum cache size to 1/2 physical RAM
• Make GC more efficient by debug.SetGCPercent
• Support go mod and deprecate godep
• Include windows platform in CI

v1.1.3

This is a maintenance release, which contains performance improvement and bug fixes.

• Add -cache cli flag to adjust underlying cache size. Under the default setting, it significantly speeds up state access, however, more RAM is occupied.
• Fix CORS problem when request with 'x-genesis-id' header.
• Fix incorrect default forkConfig in custom net configuration.

Monet (v1.1.2)

This release will activate forks VIP-191, ETH-CONST on Mainnet, at block # 3,337,300 (~ Mon, 22 Jul 2019 06:00 GMT). All nodes are required to be upgraded ASAP.

For master nodes, -skip-logs flag is recommended to be added upon startup command line, or it will take about ONE HOUR to rebuild logs database, during which the node keeps OUT-OF-SERVICE.

---

Notable changes compared to v1.0.x

• Extends transaction model to support VIP-191

• Expose gasPayer to VM context via Extension builtin contract.

• Fork config for custom network

• Improve consistency of underlying db

• API changes:

  • deprecate POST /accounts/{address}
  • deprecate POST /accounts
  • enhance POST /accounts/*
  • VIP-191 related fields added to tx/block models

• New fork ETH_CONST includes new opcodes EXTCODEHASH, CREATE2, SHL, SHR, SAR

• Fix goroutine panic on accessing ws /subscriptions/beat (invalid bloom K when a block contains mass of txs)

• Adjust TolerableBlockPackingTime from 2s to 500ms

• Easier small tx adoption

• Improve db performance

Monet (v1.1.1)

This release implements new opcodes introduced by Ethereum Constantinople update. A new fork called ETH_CONST will be activated on testnet to support these new opcodes at block # 3,192,500 (~ Mon, 1 July 2019 04:00 GMT). Any nodes running on testnet are encouraged to be upgraded ASAP.

The mainnet activation time is still TBD.

• Fix history transfer logs (re-sync required)
• Fix goroutine panic on accessing ws /subscriptions/beat (invalid bloom K when a block contains mass of txs)
• Adjust TolerableBlockPackingTime from 2s to 500ms
