IMPORTANT! READ THIS FIRST

Please read the following WARNINGs in their entirety before upgrading.

WARNING: Please be aware that using this node on chainstate prior to this release will cause
the node to spend up to 30 minutes migrating the data to a new schema.
Depending on the storage medium, this may take even longer.

WARNING: This migration process cannot be interrupted. If it is, the chainstate
will be irrecovarably corrupted and require a sync from genesis.

WARNING: You will need at least 2x the disk space for the migration to work.
This is because a copy of the chainstate will be made in the same directory in
order to apply the new schema.

It is highly recommended that you back up your chainstate before running
this version of the software on it.

Changed

• The MARF implementation will now defer calculating the root hash of a new trie
  until the moment the trie is committed to disk. This avoids gratuitous hash
  calculations, and yields a performance improvement of anywhere between 10x and
  200x (#3041).
• The MARF implementation will now store tries to an external file for instances
  where the tries are expected to exceed the SQLite page size (namely, the
  Clarity database). This improves read performance by a factor of 10x to 14x
  (#3059).
• The MARF implementation may now cache trie nodes in RAM if directed to do so
  by an environment variable (#3042).
• Sortition processing performance has been improved by about an order of
  magnitude, by avoiding a slew of expensive database reads (#3045).
• Updated chains coordinator so that before a Stacks block or a burn block is processed,
  an event is sent through the event dispatcher. This fixes #3015.
• Expose a node's public key and public key hash160 (i.e. what appears in
  /v2/neighbors) via the /v2/info API endpoint (#3046)
• Reduced the default subsequent block attempt timeout from 180 seconds to 30
  seconds, based on benchmarking the new MARF performance data during a period
  of network congestion (#3098)
• The blockstack-core binary has been renamed to stacks-inspect.
  This binary provides CLI tools for chain and mempool inspection.
