Bitcoin Core version 0.9.2 is now available from:
|
|
|
|
https://bitcoin.org/bin/0.9.2/
|
|
|
|
This is a new minor version release, bringing mostly bug fixes and some minor
|
|
improvements. OpenSSL has been updated because of a security issue (CVE-2014-0224).
|
|
Upgrading to this release is recommended.
|
|
|
|
Please report bugs using the issue tracker at github:
|
|
|
|
https://github.com/bitcoin/bitcoin/issues
|
|
|
|
How to Upgrade
|
|
--------------
|
|
|
|
If you are running an older version, shut it down. Wait until it has completely
|
|
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
|
|
bitcoind/bitcoin-qt (on Linux).
|
|
|
|
If you are upgrading from version 0.7.2 or earlier, the first time you run
|
|
0.9.2 your blockchain files will be re-indexed, which will take anywhere from
|
|
30 minutes to several hours, depending on the speed of your machine.
|
|
|
|
Downgrading warnings
|
|
--------------------
|
|
|
|
The 'chainstate' for this release is not always compatible with previous
|
|
releases, so if you run 0.9.x and then decide to switch back to a
|
|
0.8.x release you might get a blockchain validation error when starting the
|
|
old release (due to 'pruned outputs' being omitted from the index of
|
|
unspent transaction outputs).
|
|
|
|
Running the old release with the -reindex option will rebuild the chainstate
|
|
data structures and correct the problem.
|
|
|
|
Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan
|
|
the blockchain for missing spent coins, which will take a long time (tens
|
|
of minutes on a typical machine).
|
|
|
|
Important changes
|
|
==================
|
|
|
|
Gitian OSX build
|
|
-----------------
|
|
|
|
The deterministic build system that was already used for Windows and Linux
|
|
builds is now used for OSX as well. Although the resulting executables have
|
|
been tested quite a bit, there could be possible regressions. Be sure to report
|
|
these on the Github bug tracker mentioned above.
|
|
|
|
Compatibility of Linux build
|
|
-----------------------------
|
|
|
|
For Linux we now build against Qt 4.6, and filter the symbols for libstdc++ and glibc.
|
|
This brings back compatibility with
|
|
|
|
- Debian 6+ / Tails
|
|
- Ubuntu 10.04
|
|
- CentOS 6.5
|
|
|
|
