Please do not report issues about Windows XP to the +[issue tracker](https://github.com/bitcoin/bitcoin/issues). + +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. + +Additional information relating to running on low-memory systems can be found +here: +[reducing-bitcoind-memory-usage.md](https://gist.github.com/laanwj/efe29c7661ce9b6620a7). + +## 0.14.1 Change log + +Detailed release notes follow. This overview includes changes that affect +behavior, not code moves, refactors and string updates.
