This makes the following changes: * In undo data and the chainstate database, the transaction nVersion field is removed from the data structures, always written as 0, and ignored when reading. * The definition of hash_serialized in gettxoutsetinfo is changed to no longer incude the nVersion field. It is renamed to hash_serialized_2 to avoid confusion. The new definition also includes transaction height and coinbase information, as this information was missing before. This depends on having a CHashVerifier-based undo data checksum verifier. Apart from changing the definition of serialized_hash, downgrading after using this patch is supported, as no release ever used the value of nVersion field in UTXO entries.

Compatibility
|
|
==============
|
|
|
|
Bitcoin Core is extensively tested on multiple operating systems using
|
|
the Linux kernel, macOS 10.8+, and Windows Vista and later.
|
|
|
|
Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support).
|
|
No attempt is made to prevent installing or running the software on Windows XP, you
|
|
can still do so at your own risk but be aware that there are known instabilities.
|
|
Please do not report issues about Windows XP to the issue tracker.
|
|
|
|
Bitcoin Core should also work on most other Unix-like systems but is not
|
|
frequently tested on them.
|
|

Notable changes

|
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.
|
|
- `pruneblockchain` now returns RPC_MISC_ERROR if the blocks cannot be pruned
|
|
because the node is not in pruned mode. Previously returned RPC_METHOD_NOT_FOUND.
|
|
- `pruneblockchain` now returns RPC_INVALID_PARAMETER if the blocks cannot be pruned
|
|
because the supplied timestamp is too late. Previously returned RPC_INTERNAL_ERROR.
|
|
- `pruneblockchain` now returns RPC_MISC_ERROR if the blocks cannot be pruned
|
|
because the blockchain is too short. Previously returned RPC_INTERNAL_ERROR.
|
|
- `setban` now returns RPC_CLIENT_INVALID_IP_OR_SUBNET if the supplied IP address
|
|
or subnet is invalid. Previously returned RPC_CLIENT_NODE_ALREADY_ADDED.
|
|
- `setban` now returns RPC_CLIENT_INVALID_IP_OR_SUBNET if the user tries to unban
|
|
a node that has not previously been banned. Previously returned RPC_MISC_ERROR.
|
|
- `removeprunedfunds` now returns RPC_WALLET_ERROR if bitcoind is unable to remove
|
|
the transaction. Previously returned RPC_INTERNAL_ERROR.
|
|
- `removeprunedfunds` now returns RPC_INVALID_PARAMETER if the transaction does not
|
|
exist in the wallet. Previously returned RPC_INTERNAL_ERROR.
|
|
- `fundrawtransaction` now returns RPC_INVALID_ADDRESS_OR_KEY if an invalid change
|
|
address is provided. Previously returned RPC_INVALID_PARAMETER.
|
|
- `fundrawtransaction` now returns RPC_WALLET_ERROR if bitcoind is unable to create
|
|
the transaction. The error message provides further details. Previously returned
|
|
RPC_INTERNAL_ERROR.
|
|
- `bumpfee` now returns RPC_INVALID_PARAMETER if the provided transaction has
|
|
descendants in the wallet. Previously returned RPC_MISC_ERROR.
|
|
- `bumpfee` now returns RPC_INVALID_PARAMETER if the provided transaction has
|
|
descendants in the mempool. Previously returned RPC_MISC_ERROR.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction has
|
|
has been mined or conflicts with a mined transaction. Previously returned
|
|
RPC_INVALID_ADDRESS_OR_KEY.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction is not
|
|
BIP 125 replaceable. Previously returned RPC_INVALID_ADDRESS_OR_KEY.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction has already
|
|
been bumped by a different transaction. Previously returned RPC_INVALID_REQUEST.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction contains
|
|
inputs which don't belong to this wallet. Previously returned RPC_INVALID_ADDRESS_OR_KEY.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction has multiple change
|
|
outputs. Previously returned RPC_MISC_ERROR.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the provided transaction has no change
|
|
output. Previously returned RPC_MISC_ERROR.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the fee is too high. Previously returned
|
|
RPC_MISC_ERROR.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the fee is too low. Previously returned
|
|
RPC_MISC_ERROR.
|
|
- `bumpfee` now returns RPC_WALLET_ERROR if the change output is too small to bump the
|
|
fee. Previously returned RPC_MISC_ERROR.
