16Compatibility
17==============
18
19Bitcoin Core is extensively tested on multiple operating systems using
20the Linux kernel, macOS 10.8+, and Windows Vista and later.
21
22Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
23No attempt is made to prevent installing or running the software on Windows XP, you
24can still do so at your own risk but be aware that there are known instabilities and issues.
25Please do not report issues about Windows XP to the issue tracker.
26
27Bitcoin Core should also work on most other Unix-like systems but is not
28frequently tested on them.
29
30Notable changes
31===============
32
33RPC changes
34-----------
35
36- The first positional argument of `createrawtransaction` was renamed from
37  `transactions` to `inputs`.
38
39- The argument of `disconnectnode` was renamed from `node` to `address`.
40
41These interface changes break compatibility with 0.14.0, when the named
42arguments functionality, introduced in 0.14.0, is used. Client software
43using these calls with named arguments needs to be updated.
44
45Mining
46------
47
48In previous versions, getblocktemplate required segwit support from downstream
49clients/miners once the feature activated on the network. In this version, it
50now supports non-segwit clients even after activation, by removing all segwit
51transactions from the returned block template. This allows non-segwit miners to
52continue functioning correctly even after segwit has activated.
53
54Due to the limitations in previous versions, getblocktemplate also recommended
55non-segwit clients to not signal for the segwit version-bit. Since this is no
56longer an issue, getblocktemplate now always recommends signalling segwit for
57all miners. This is safe because ability to enforce the rule is the only
58required criteria for safe activation, not actually producing segwit-enabled
59blocks.
60
61UTXO memory accounting
62----------------------
63
64Memory usage for the UTXO cache is being calculated more accurately, so that
65the configured limit (`-dbcache`) will be respected when memory usage peaks
66during cache flushes.  The memory accounting in prior releases is estimated to
67only account for half the actual peak utilization.
68
69The default `-dbcache` has also been changed in this release to 450MiB.  Users
70who currently set `-dbcache` to a high value (e.g. to keep the UTXO more fully
71cached in memory) should consider increasing this setting in order to achieve
72the same cache performance as prior releases.  Users on low-memory systems
73(such as systems with 1GB or less) should consider specifying a lower value for
74this parameter.
75
76Additional information relating to running on low-memory systems can be found
77here:
78[reducing-bitcoind-memory-usage.md](https://gist.github.com/laanwj/efe29c7661ce9b6620a7).
