v3.2.5

Recommended Upgrade

• Mainnet and testnet checkpoints added
• Adds support for mixed tx ordering, alongside time and fee ordering for miners.
• Many fixes and performance improvements across the board
• Key performance improvements:
  • Related to https://github.com/DeFiCh/ain/issues/1730 (#1755, #1758, #1769, #1768, #1757)
  • Thread pool and concurrency optimizations (#1773, #1762, #1765)
• Broad-spectrum CI and testing fixes (#1772, #1744)

Upgrade Notes

• For >= 3.2.0 and <= 3.2.3, reindex is recommended, but optional and can be drop in-upgrade.
  • reindex fixes edge cases where some entries were missing in the outputs of listaccounthistory (fixed in: #1700) and account history related RPC. This does not affect consensus, UTXOs or account balances.
• For nodes >=3.0.x, one of the following is required:
  • Sync from any of snapshots from the DeFiChain team (below)
  • Any of your own snapshots or data backups before block 2480466 (b41a1d51d80381d3b14be24bc8b2a5524e1c698f5d7cffe5ec4f7b6807ce935a).
• For all other updates, one of the following is required: a fresh sync, the most recent snapshot.
• For nodes that are being restored from recent snapshot, as with all updates before: -rescan for the wallet txs and additionally -spv_resync for users who hold BTC. If either isn't used, they may not be shown in the wallet until rescanned/resynced.

Flag Changes

• Added -dftxworkers=<0/N>: No. of threads in the thread pool for DFTx worker task pool. 0 = automatic.
• Added -txordering=entrytime/fee/mixed: mixed uses a random selection of entrytime or fee ordering.
