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:

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, 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.
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.
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.
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.
Detailed release notes follow. This overview includes changes that affect behavior, not code moves, refactors and string updates. For convenience in locating the code changes and accompanying discussion, both the pull request and git merge commit are mentioned.
