How to Upgrade
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
If you are running an older version, shut it down. Wait until it has completely
|
2017-10-09 10:45:01 +02:00
|
|
|
shut down (which might take a few minutes for older versions), then run the
|
2017-09-12 10:04:27 +02:00
|
|
|
installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
|
2017-08-14 16:45:58 +02:00
|
|
|
or `bitcoind`/`bitcoin-qt` (on Linux).
|
|
|
|
|
|
2019-04-16 14:05:36 +02:00
|
|
|
Upgrading directly from a version of Bitcoin Core that has reached its EOL is
|
2019-10-01 13:04:40 +02:00
|
|
|
possible, but it might take some time if the datadir needs to be migrated. Old
|
2019-04-16 14:05:36 +02:00
|
|
|
wallet versions of Bitcoin Core are generally supported.

Compatibility
|
|
|
|
|
==============
|
|
|
|
|
|
2018-12-17 13:12:05 +01:00
|
|
|
Bitcoin Core is supported and extensively tested on operating systems using
|
2019-07-24 22:40:32 +02:00
|
|
|
the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended
|
2018-12-17 13:12:05 +01:00
|
|
|
to use Bitcoin Core on unsupported systems.
|
2017-01-14 02:21:41 +01:00
|
|
|
|
|
|
|
|
Bitcoin Core should also work on most other Unix-like systems but is not
|
2019-07-24 22:40:32 +02:00
|
|
|
as frequently tested on them.
|
2016-06-22 16:29:00 +02:00
|
|
|
|
2019-10-01 13:04:40 +02:00
|
|
|
From Bitcoin Core 0.17.0 onwards, macOS versions earlier than 10.10 are no
|
|
|
|
|
longer supported, as Bitcoin Core is now built using Qt 5.9.x which requires
|
|
|
|
|
macOS 10.10+. Additionally, Bitcoin Core does not yet change appearance when
|
2018-11-06 14:14:40 +01:00
|
|
|
macOS "dark mode" is activated.
|
|
|
|
|
|
2019-10-01 13:04:40 +02:00
|
|
|
In addition to previously supported CPU platforms, this release's pre-compiled
|
|
|
|
|
distribution provides binaries for the RISC-V platform.

Build System
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
- OpenSSL is no longer used by Bitcoin Core. The last usage of the library
|
|
|
|
|
was removed in #17265.
|

New RPCs
|

|
|
|

|
|
|
New settings

Updated RPCs

|
|
|
|
|
|
|
|
|
|
Note: some low-level RPC changes mainly useful for testing are described in the

GUI changes

|
Wallet
|
|
|
|
|
------
|
|
|
|
|
|
|
|
|
|
- The wallet now by default uses bech32 addresses when using RPC, and creates native segwit change outputs.
|
2019-10-21 22:22:56 +02:00
|
|
|
- The way that output trust was computed has been fixed in #16766, which impacts confirmed/unconfirmed balance status and coin selection.

Tests

|
|

|
|
|
- `-fallbackfee` was 0 (disabled) by default for the main chain, but 0.0002 by default for the test chains. Now it is 0
|
|
|
|
|
by default for all chains. Testnet and regtest users will have to add `fallbackfee=0.0002` to their configuration if
|
|
|
|
|
they weren't setting it and they want it to keep working like before. (#16524)
