Bitcoin-Qt 0.6.2
================

Bitcoin version 0.6.2 is now available for download at:
<http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.2/>

This is a bug-fix and code-cleanup release, with no major new features.

Please report bugs using the github issue tracker at:
<https://github.com/bitcoin/bitcoin/issues>


NOTABLE CHANGES
---------------

Much faster shutdowns. However, the blkindex.dat file is no longer
portable to different data directories by default. If you need a
portable blkindex.dat file then run with the new -detachdb=1 option
or the "Detach databases at shutdown" GUI preference.

Fixed <https://github.com/bitcoin/bitcoin/issues/1065>, a bug that
could cause long-running nodes to crash.

Mac and Windows binaries are compiled against OpenSSL 1.0.1b (Linux
binaries are dynamically linked to the version of OpenSSL on the system).
