This is a maintenance release bringing bugfixes and substantial performance improvements.
4.2.1
- Decrease node startup time and memory use by avoiding needless checks when loading the database.
- Improve startup time by avoiding processing already processed protocol updates.
- Decrease memory usage by not storing genesis blocks. This has the effect that the database produced by node versions >= 4.2.* cannot be used by node versions <= 4.1. The other direction works.
- Increase precision of block arrive and block receive times in the GetBlockInfo query.
