This release includes the following features and fixes:

RPC Changes

• The Chronik Electrum blockchain.block.headers RPC now returns up to
  2016 block headers, as per the documentation. Previously, it mistakenly
  applied the page limits relevant to Chronik's block and headers endpoints
  and thus returned an error if more than 500 headers were requested.
• The getblockchaininfo RPC now has a new field "finalized_blockhash" which
  gives the hash of the highest block that is finalized by Avalanche, or
  the hash of the genesis block if no block is finalized by Avalanche.

Updated settings

• The maximum allowed value for the -dbcache configuration option has been
  dropped. Note that before this change, large -dbcache values were automatically
  reduced to 16 GiB (1 GiB on 32 bit systems).

Bugfix

• Fixed a bug where the getavalancheinfo RPC could return the wrong status
  for the local proof if it was rejected by avalanche vote.
