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 and issues. |
||||||
|
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 |
||||||
|
=============== |
||||||
|
|
||||||
|
RPC changes |
||||||
|
----------- |
||||||
|
|
||||||
|
- The first positional argument of `createrawtransaction` was renamed from |
||||||
|
`transactions` to `inputs`. |
||||||
|
|
||||||
|
- The argument of `disconnectnode` was renamed from `node` to `address`. |
||||||
|
|
||||||
|
These interface changes break compatibility with 0.14.0, when the named |
||||||
|
arguments functionality, introduced in 0.14.0, is used. Client software |
||||||
|
using these calls with named arguments needs to be updated. |
||||||
|
|
||||||
|
Mining |
||||||
|
------ |
||||||
|
|
||||||
|
In previous versions, getblocktemplate required segwit support from downstream |
||||||
|
clients/miners once the feature activated on the network. In this version, it |
||||||
|
now supports non-segwit clients even after activation, by removing all segwit |
||||||
|
transactions from the returned block template. This allows non-segwit miners to |
||||||
|
continue functioning correctly even after segwit has activated. |
||||||
|
|
||||||
|
Due to the limitations in previous versions, getblocktemplate also recommended |
||||||
|
non-segwit clients to not signal for the segwit version-bit. Since this is no |
||||||
|
longer an issue, getblocktemplate now always recommends signalling segwit for |
||||||
|
all miners. This is safe because ability to enforce the rule is the only |
||||||
|
required criteria for safe activation, not actually producing segwit-enabled |
||||||
|
blocks. |
||||||
|
|
||||||
|
UTXO memory accounting |
||||||
|
---------------------- |
||||||
|
|
||||||
|
Memory usage for the UTXO cache is being calculated more accurately, so that |
||||||
|
the configured limit (`-dbcache`) will be respected when memory usage peaks |
||||||
|
during cache flushes. The memory accounting in prior releases is estimated to |
||||||
|
only account for half the actual peak utilization. |
||||||
|
|
||||||
|
The default `-dbcache` has also been changed in this release to 450MiB. Users |
||||||
|
who currently set `-dbcache` to a high value (e.g. to keep the UTXO more fully |
||||||
|
cached in memory) should consider increasing this setting in order to achieve |
||||||
|
the same cache performance as prior releases. Users on low-memory systems |
||||||
|
(such as systems with 1GB or less) should consider specifying a lower value for |
||||||
|
this parameter. |
||||||
|
|
||||||
|

||||||
