+Bitcoin Core version 0.14.1 is now available from:
+
+  <https://bitcoin.org/bin/bitcoin-core-0.14.1/>
+
+This is a new minor version release, including various bugfixes and
+performance improvements, as well as updated translations.
+
+Please report bugs using the issue tracker at github:

+
+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.
+
+Additional information relating to running on low-memory systems can be found
+here:
+[reducing-bitcoind-memory-usage.md](https://gist.github.com/laanwj/efe29c7661ce9b6620a7).
