bitcoin-sv/bitcoin-sv v1.0.7

Bitcoin SV version 1.0.7 Release Notes

on GitHub

Headline changes since 1.0.6

• Removed performance penalty for long chains. Mempool performance does not depend on the transaction's chain length anymore.
• Legacy block assembler removed; support for low priority / free transactions removed.
• Refactoring of CCoinView.
• P2P improvements.

Full list of changes between 1.0.6 and 1.0.7.beta

• Increased default maximum ancestors count for paying transactions to 1000.
• Removing transactions from the mempool when a new block is mined is much faster. As a consequence, block propagation is faster.
• More efficient mempool transaction eviction algorithm.
• Removed the Legacy block assembler; Journaling block assembler is now the only block assembler available.
• Efficient detection of the CPFP (child pays for the parent) groups.
• Limiting the total size of the low-paying transactions in the mempool as the percent of the mempool size.
• Limiting the ancestors count for the low-paying transactions to 25, and as consequence, limiting the maximal size of the CPFP groups.
• Stopped limitting transaction chains by ancestors size in the mempool.
• Stopped limitting transaction chains by descedant statistics, both size and count.
• Removed concept of the "high priority / free transactions". We are not accepting nor relaying them any more.
• Added command line switches:
  • mempoolmaxpercentcpfp, Percentage of total mempool size to allow for low paying transactions. Default: 10%
  • limitcpfpgroupmemberscount, Maximal number of non-paying ancestors a single transaction can have. Thus, the maximal size of a CPFP group. Default 25.
  • disablebip30checks Disables BIP30 checks when connecting a block. Not active on the mainnet.
• Removed command line switches:
  • limitancestorsize, Not tracking ancestors size in the new implementation.
  • limitdescendantcount, limitdescendantsize Not keeping descendant statistics in the new implementation.
  • limitfreerelay relaypriority printpriority blockprioritypercentage Removed concept of the "free / high priority" transactions
• The prioritisetransaction RPC method ignores the first positional argument (modified priority), which must be 0, and uses only the second argument (modified fee) into account.
• Other changes to the RPC methods, added and removed JSON entries:

• Implement HTTP streaming for getblocktemplate
• Do not load large blocks into memory
• Performance - CCoinView refactoring
• Endomorphism is now ON by default in libsecp256k1
• New configurable connection timeout for validating blocks.
• Serialize in getblock RPC without cs_main
• Maximum size of INV messages configurable
• Change -rejectmempoolrequest default to true

• Message processing stall remedy
• Send GETDATA for blocks over the higher priority stream.
• Fix: Slow reading of coins from database when using leveldb iterators
• sendrawtransaction RPC - fix PrioritiseTransaction/ClearPrioritisation usage to be exception safe.
• sendrawtransaction RPC - functional test – send already known transaction and create block.
• sendrawtransaction RPC - check if transaction is already known before validation starts.
• Remove bitcoin-seeder.
• Fix: Coredump at shutdown with scriptCheckQueuePool
• Fix: Consolidation tx option 'acceptnonstdconsolidationinput' uses wrong type
• Fix: Consolidation variable name and update function to respect interface

• Fix: Implicit loop conversions
• Unused code removed
• False positive check for null dereferencing in merkle proof
• Explicitly define the missing special members for ZMQPublisher
