Release notes:

Stability improvements

• Improvements to the internal scheduler that core uses to load balance work between networking and ledger related tasks - this speeds up considerably catchup while reducing latency for processing SCP messages
• Fixed a crash when shutdown is called while catching up
• Reduce chance of triggering catchup when out of sync and out of order ledgers are received - this could happen on nodes that are running on low end hardware
• Avoid replaying many ledgers when rejoining the network - this could cause the node to hang while applying many ledgers
• Improve error messages when running into crypto errors
• Cleanup buckets folder after running a command line catchup - this releases disk space properly.
• Use a more recent version of sqlite

New features

• Improvements to transaction simulation code. Traffic scaling, and warm up.
