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 Vista and later. 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
|
|
|
|
|
===============
|
|
|
|
|
|
|
|
|
|
GCC 4.8.x
|
|
|
|
|
--------------
|
|
|
|
|
The minimum version of GCC required to compile Bitcoin Core is now 4.8. No effort will be
|
|
|
|
|
made to support older versions of GCC. See discussion in issue #11732 for more information.
|
|
|
|
|
|
|
|
|
|
HD-wallets by default
|
|
|
|
|
---------------------
|
|
|
|
|
Due to a backward-incompatible change in the wallet database, wallets created
|
|
|
|
|
with version 0.16.0 will be rejected by previous versions. Also, version 0.16.0
|
|
|
|
|
will only create hierarchical deterministic (HD) wallets.
|
|
|
|
|
|
|
|
|
|
Custom wallet directories
|
|
|
|
|
---------------------
|
|
|
|
|
The ability to specify a directory other than the default data directory in which to store
|
|
|
|
|
wallets has been added. An existing directory can be specified using the `-walletdir=<dir>`
|
|
|
|
|
argument. Wallets loaded via `-wallet` arguments must be in this wallet directory. Care should be taken
|
|
|
|
|
when choosing a wallet directory location, as if it becomes unavailable during operation,
|
|
|
|
|
funds may be lost.
|
|
|
|
|
|
|
|
|
|
Default wallet directory change
|
|
|
|
|
--------------------------
|
|
|
|
|
On new installations (if the data directory doesn't exist), wallets will now be stored in a
|
|
|
|
|
new `wallets/` subdirectory inside the data directory. If this `wallets/` subdirectory
|
|
|
|
|
doesn't exist (i.e. on existing nodes), the current datadir root is used instead, as it was.
|
|
|
|
|
|
|
|
|
|
Low-level RPC changes
|
|
|
|
|
----------------------
|
|
|
|
|
- The deprecated RPC `getinfo` was removed. It is recommended that the more specific RPCs are used:
|
|
|
|
|
* `getblockchaininfo`
|
|
|
|
|
* `getnetworkinfo`
|
|
|
|
|
* `getwalletinfo`
|
|
|
|
|
* `getmininginfo`
|
|
|
|
|
- The wallet RPC `getreceivedbyaddress` will return an error if called with an address not in the wallet.
|
|
|
|
|
|
|
|
|
|
Changed command-line options
|
|
|
|
|
-----------------------------
|
|
|
|
|
- `-debuglogfile=<file>` can be used to specify an alternative debug logging file.
