Release Note

This release provides a few patches and improvements.

A randomx_bulk_hashing_iterations configuration parameter is introduced - tweaking it allows increasing the mining performance on powerful CPUs significantly.
The memory pool is now persisted before shutdown and loaded on startup so pending transactions do not get lost on restart increasing the joining speed and decreasing the chance the data attached to v2 transaction headers gets lost when poorly seeded.
The data attached to v2 transaction headers is propagated to the trusted peers to increase the initial seeding coverage.
A bug is fixed where RocksDB may not have sufficient time to shut down.
A bug is fixed, which would delay the network joining by 30 seconds.
An improvement is made, which relaxes the bandwidth requirements on network join.
