Low-level RPC changes
---------------------
+- The new database model no longer stores information about transaction
+ versions of unspent outputs. This means that:
+ - The `gettxout` RPC no longer has a `version` field in the response.
+ - The `gettxoutsetinfo` RPC reports `hash_serialized_2` instead of `hash_serialized`,
+ which does not commit to the transaction versions of unspent outputs, but does
+ commit to the height and coinbase information.
+ - The `getutxos` REST path no longer reports the `txvers` field in JSON format,
+ and always reports 0 for transaction versions in the binary format
+
- Error codes have been updated to be more accurate for the following error cases:
- `getblock` now returns RPC_MISC_ERROR if the block can't be found on disk (for
example if the block has been pruned). Previously returned RPC_INTERNAL_ERROR.
