David A. Harding cbebe461ff Releases: Variablize Release Notes 
Add additional variables to the release note files to allow setting the
version number and date.  The version number is required, and can be
used to automatically set the release notes title.  The date is optional
and can be set hours/days after the release.

Additionally, a Makefile test is added that checks whether the download
files exist on the Bitcoin.org server.  This can help prevent creating a
broken Download page.

* Set variables for all previous releases

* Document variables in README.md

* Update code and templates to use variables

* Add the Download page links to the "dl" CSS class. Also add newlines
  to make the HTML a bit easier to parse using sed

* Add a new Liquid plugin to print warnings. This is used to print a
  non-error warning if any release is created without the optional date

0.7.2 2012-12-14 Bitcoin-Qt version 0.7.2 released

Bitcoin-Qt version 0.7.2 is now available from: http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.7.2

This is a bug-fix minor release.

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 were running on Linux with a version that might have been compiled with a different version of Berkeley DB (for example, if you were using an Ubuntu PPA version), then run the old version again with the -detachdb argument and shut it down; if you do not, then the new version will not be able to read the database files and will exit with an error.

Explanation of -detachdb (and the new "stop true" RPC command): The Berkeley DB database library stores data in both ".dat" and "log" files, so the database is always in a consistent state, even in case of power failure or other sudden shutdown. The format of the ".dat" files is portable between different versions of Berkeley DB, but the "log" files are not-- even minor version differences may have incompatible "log" files. The -detachdb option moves any pending changes from the "log" files to the "blkindex.dat" file for maximum compatibility, but makes shutdown much slower. Note that the "wallet.dat" file is always detached, and versions prior to 0.6.0 detached all databases at shutdown.

Bug fixes

  • Prevent RPC move from deadlocking. This was caused by trying to lock the database twice.

  • Fix use-after-free problems in initialization and shutdown, the latter of which caused Bitcoin-Qt to crash on Windows when exiting.

  • Correct library linking so building on Windows natively works.

  • Avoid a race condition and out-of-bounds read in block creation/mining code.

  • Improve platform compatibility quirks, including fix for 100% CPU utilization on FreeBSD 9.

  • A few minor corrections to error handling, and updated translations.

  • OSX 10.5 supported again
