6+

Upgrading and downgrading
13+
=========================
14+
15+
How to Upgrade
16+
--------------
17+
18+
If you are running an older version, shut it down. Wait until it has completely
19+
shut down (which might take a few minutes for older versions), then run the
20+
installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
21+
bitcoind/bitcoin-qt (on Linux).
22+
23+
Downgrade warning
24+
------------------
25+
26+
Because release 0.10.0 and later makes use of headers-first synchronization and
27+
parallel block download (see further), the block files and databases are not
28+
backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:
29+
30+
* Blocks will be stored on disk out of order (in the order they are
31+
received, really), which makes it incompatible with some tools or
32+
other programs. Reindexing using earlier versions will also not work
33+
anymore as a result of this.
34+
35+
* The block index database will now hold headers for which no block is
36+
stored on disk, which earlier versions won't support.
37+
38+
If you want to be able to downgrade smoothly, make a backup of your entire data
39+
directory. Without this your node will need start syncing (or importing from
40+
bootstrap.dat) anew afterwards. It is possible that the data from a completely
41+
synchronised 0.10 node may be usable in older versions as-is, but this is not
42+
supported and may break as soon as the older version attempts to reindex.
43+
44+
This does not affect wallet forward or backward compatibility.
45+
46+

Bitcoin Core version 0.9.4 is now available from:

16+
shut down (which might take a few minutes for older versions), then run the

installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or

OpenSSL Warning
21+
================
22+
23+
OpenSSL 1.0.0p / 1.0.1k was recently released and is being pushed out by
24+
various operating system maintainers. Review by Gregory Maxwell determined that
25+
this update is incompatible with the Bitcoin system and could lead to consensus
26+
forks.
27+
28+
Bitcoin Core released binaries from https://bitcoin.org are unaffected,
29+
as are any built with the gitian deterministic build system.
30+
31+
However, if you are running either
32+
33+
- The Ubuntu PPA from https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
34+
- A third-party or self-compiled Bitcoin Core
35+
36+
upgrade to Bitcoin Core 0.9.4, which includes a workaround, **before** updating
37+
OpenSSL.
38+
39+
The incompatibility is due to the OpenSSL update changing the
40+
behavior of ECDSA validation to reject any signature which is
41+
not encoded in a very rigid manner. This was a result of
42+
OpenSSL's change for CVE-2014-8275 "Certificate fingerprints
43+
can be modified".
44+
45+
We are specifically aware of potential hard-forks due to signature
46+
encoding handling and had been hoping to close them via BIP62 in 0.10.
47+
BIP62's purpose is to improve transaction malleability handling and
48+
as a side effect rigidly defines the encoding for signatures, but the
49+
overall scope of BIP62 has made it take longer than we'd like to
50+
deploy.
51+
52+
