How to Upgrade
|
|
==============
|
|
|
|
If you are running an older version, shut it down. Wait until it has completely
|
|
shut down (which might take a few minutes for older versions), then run the
|
|
installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
|
|
or `bitcoind`/`bitcoin-qt` (on Linux).
|
|
|
|
The first time you run version 0.15.0, your chainstate database will be converted to a
|
|
new format, which will take anywhere from a few minutes to half an hour,
|
|
depending on the speed of your machine.
|
|
|
|
Note that the block database format also changed in version 0.8.0 and there is no
|
|
automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading
|
|
directly from 0.7.x and earlier without redownloading the blockchain is not supported.
|
|
However, as usual, old wallet versions are still supported.
|
|
|
|
Downgrading warning
|
|
-------------------
|
|
|
|
The chainstate database for this release is not compatible with previous
|
|
releases, so if you run 0.15 and then decide to switch back to any
|
|
older version, you will need to run the old release with the `-reindex-chainstate`
|
|
option to rebuild the chainstate data structures in the old format.
|
|
|
|
If your node has pruning enabled, this will entail re-downloading and
|
|
processing the entire blockchain.
|
|
|
|
Compatibility
|
|
==============
|
|
|
|
Bitcoin Core is extensively tested on multiple operating systems using
|
|
the Linux kernel, macOS 10.8+, and Windows 7 and newer (Windows XP is not supported).
|
|
|
|
Bitcoin Core should also work on most other Unix-like systems but is not
|
|
frequently tested on them.
|
|
|
|
Notable changes
|
|
===============
|
|
|
|
RPC changes
|
|
------------
|
|
|
|
### Low-level changes
|
|
|
|
- The `createrawtransaction` RPC will now accept an array or dictionary (kept for compatibility) for the `outputs` parameter. This means the order of transaction outputs can be specified by the client.
|
|
- The `fundrawtransaction` RPC will reject the previously deprecated `reserveChangeKey` option.
|
|
- `sendmany` now shuffles outputs to improve privacy, so any previously expected behavior with regards to output ordering can no longer be relied upon.
|
|
- The new RPC `testmempoolaccept` can be used to test acceptance of a transaction to the mempool without adding it.
|
|
- JSON transaction decomposition now includes a `weight` field which provides
|
|
the transaction's exact weight. This is included in REST /rest/tx/ and
|
|
/rest/block/ endpoints when in json mode. This is also included in `getblock`
|
|
(with verbosity=2), `listsinceblock`, `listtransactions`, and
|
|
`getrawtransaction` RPC commands.
|
|
|
|
External wallet files
|
|
---------------------
|
|
|
|
The `-wallet=<path>` option now accepts full paths instead of requiring wallets
|
|
to be located in the -walletdir directory.
|
|
|
|
Newly created wallet format
|
|
---------------------------
|
|
|
|
If `-wallet=<path>` is specified with a path that does not exist, it will now
|
|
create a wallet directory at the specified location (containing a wallet.dat
|
|
data file, a db.log file, and database/log.?????????? files) instead of just
|
|
creating a data file at the path and storing log files in the parent
|
|
directory. This should make backing up wallets more straightforward than
|
|
before because the specified wallet path can just be directly archived without
|
|
having to look in the parent directory for transaction log files.
|
|
|
|
For backwards compatibility, wallet paths that are names of existing data files
|
|
in the `-walletdir` directory will continue to be accepted and interpreted the
|
|
same as before.
|
|
|
|
Low-level RPC changes
|
|
---------------------
|
|
|
|
- When bitcoin is not started with any `-wallet=<path>` options, the name of
|
|
the default wallet returned by `getwalletinfo` and `listwallets` RPCs is
|
|
now the empty string `""` instead of `"wallet.dat"`. If bitcoin is started
|
|
with any `-wallet=<path>` options, there is no change in behavior, and the
|
|
name of any wallet is just its `<path>` string.
|
|
|
|
### Logging
|
|
|
|
- The log timestamp format is now ISO 8601 (e.g. "2018-02-28T12:34:56Z").
|
|
|
|
Miner block size removed
|
|
------------------------
|
|
|
|
The `-blockmaxsize` option for miners to limit their blocks' sizes was
|
|
deprecated in V0.15.1, and has now been removed. Miners should use the
|
|
`-blockmaxweight` option if they want to limit the weight of their blocks'
|
|
weights.
|
|
|
|
Python Support
|
|
--------------
|
|
|
|
Support for Python 2 has been discontinued for all test files and tools.
