• improve the re-schedule condition of packing process(#409)
• cover all branches in VM tracer(#405)

• logdb: upgrade go-sqlite (#377)
• logdb: cache query statements (#377)

v1.3.5

v1.3.4

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

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

• Special treatment for locally submitted txs, which will not be dropped in the case of congestion.
• Improve tx broadcast in p2p network.
• Fix: memory leak in p2p/discovery.

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,
  ...
  "transactions": [
    {
      "id": "0x1394889a4d736f30fc3e3557aab8d90565161ddf001d908ed5bf708863866a3a",
      ...
      "clauses": [
         ...
      ],
      ...
      "reverted": false,
      "outputs": [
        {
          "events": [
            ...
          ],
          ...
}

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.
