Bitcoin Core 0.14.2 Released

[achow101]

Bitcoin Core version 0.14.2 is now available from:

  <https://bitcoin.org/bin/bitcoin-core-0.14.2/>

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:

  <https://github.com/bitcoin/bitcoin/issues>

To receive security and update notifications, please subscribe to:

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
===============

miniupnp CVE-2017-8798
----------------------------

Bundled miniupnpc was updated to 2.0.20170509. This fixes an integer signedness error
(present in MiniUPnPc v1.4.20101221 through v2.0) that allows remote attackers
(within the LAN) to cause a denial of service or possibly have unspecified
other impact.

This only affects users that have explicitly enabled UPnP through the GUI
setting or through the `-upnp` option, as since the last UPnP vulnerability
(in Bitcoin Core 0.10.3) it has been disabled by default.

If you use this option, it is recommended to upgrade to this version as soon as
possible.

Known Bugs
==========

Since 0.14.0 the approximate transaction fee shown in Bitcoin-Qt when using coin
control and smart fee estimation does not reflect any change in target from the
smart fee slider. It will only present an approximate fee calculated using the
default target. The fee calculated using the correct target is still applied to
the transaction and shown in the final send confirmation dialog.

0.14.2 Change log

Hi, I would like to know if it is the latest version.

Bitcoin Core 0.14.2 is the latest version of Bitcoin Core.

I need download the last versión the official wallet.

There is no such thing as "the official wallet" of Bitcoin. No wallet is "the official wallet".

[slaithe]

this one is not official wallet, its like full wallet with all history

Good, I hope this version will take up more CPU space

[Amph]

this one is not official wallet, its like full wallet with all history

well for official wallet they usually me an the one that is supported by the core dev team

everything else is considered a fork in the same way as any altcoin even the exchange agree with this view

[Icon]

i am guessing no, but worth the ask, is this new update going to be compatible with the Segwit2x that's suppose to go live August 1'st? and BIP 148?

[achow101]

No.

The Bitcoin Core developers do not support Segwit2x or any of the other hard fork proposals. There also is not consensus about BIP 148 so that is not supported either.

[Meuh6879]

Bitcoin BTC1 = SegWit2x (Segwit + 2Mb block).
Bitcoin Knots = Segwit BIP148 if you activate the command line (if not, it's a Bitcoin Core).
Bitcoin Core = Follow the majority.
Bitcoin UASF = Enforce BIP148 (Segwit) at 1st August.
Bitcoin BU = No Segwit.
Bitcoin Classic = No Segwit.
Bitcoin XT = No Segwit.

Others softwares don't have Network history feature (complete local blockchain).

How come this website says, download bitcoin core with BIP 148 support? 

https://bitcoinuasf.org/


they got it wrong?

That is fork of Bitcoin Core which has a fairly small patchset on top of it for BIP 148 support. It is basically a version of Bitcoin Core that has BIP 148 support, but it is not published by Core nor endorsed by Core.

[Meuh6879]

i prefer Bitcoin Knots, you can choose to enforce BIP148 (marker +BIP148 on uacomment) or not ... with others tools integrated from githup open deposit sources (fork).

There is no official wallet, but we can still download a wallet to make a cold wallet on the computer to ensure security

[AgatioX]

I'm so confused already. 
Will there be 2 bitcoins after 1 august or not?
Some ppl say there will be no softfork now,its canceled.So there is no needs to look for wallet wich will be ready to show you both btc.
Some say there will be UASF and 2 coins and we need to hodl on wallets to get both. 

What will happen?Wich wallet should I install and hodl or not to hodl?

This wallet supports UASF and 2 coins?First time I tried to download core database by HDD died

[achow101]

I'm so confused already.  
Will there be 2 bitcoins after 1 august or not?

Possibly. There may or may not be chain split; it depends on whether enough miners support BIP 148.

What will happen?

No one knows. That requires us to be able to predict the future, which is literally impossible. No one can say what will or will not happen until after August 1st.

Wich wallet should I install and hodl or not to hodl?

Choose whatever wallet you want to use. Just check that they are supporting the proposal you support and that they have proper protections in place to ensure you are following the chain that you want to if a fork happens.

Asking about UASF or BIP 148 is off topic for this thread.

No. Bitcoin Core does not support any current UASF.

Hi everyone,

I have a question about the security of the file provided in the link at the beginning of this post, and is that after downloading the file and uploading it to virustotal.com there are five detections of malware, likewise as far as I know the sha256sum does not correspond the one provided by the same page, could someone confirm the latter, as well as ensure the reliability of the file?

The link of the analysis:

Thank's everyone !

Developers should support Bitcoin Core or other hard fork proposals.

Thank's everyone !

The SHA256 of the file on virustotal matches that in the SHA256SUMS.asc file, so the download is legitimate. The executable is fine and safe. The detections on virustotal are false positives. Bitcoin Core is often flagged as a virus because it looks for a wallet.dat file (so usually considered a coin stealer) and it contains mining logic (so also considered a bitcoin miner). These are true, but are also integral to Bitcoin Core functioning properly; it is the software the makes the wallet.dat file that many viruses try to steal. It also contains logic for mining blocks, but this is only for testnet and regtest networks now. If you have verified that the sha256 of the file matches the sha256 in SHA256SUMS.asc and you have verified the PGP signature in SHA256SUMS.asc, then the file is safe and not a virus.

Thanks alot for explanations and sorry about offtopic.

Well lets wait for fork support implementation (if there will be one in the end)

Sorry mate, i think i didn't do it right, cause i checked the SHA256 of the file through the terminal on linux using the sha256sum command and the result didnt' match the sha256sum.asc file, Could someone explain how to verify sha256 and PGP signatures ?, (i think it would be an important contribution for the newbies like me even if it is offtopic)
