Bitcoin version 0.6.1rc2 is now available for download at: @p{brk}
  @s{(link)} @p{par}

This is a bug-fix and code-cleanup release, with no major new features. @p{par}

NOTABLE CHANGES @p{brk}
=============== @p{par}

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

Mac and Windows binaries are compiled against OpenSSL 1.0.1b (Linux @p{brk}
binaries are dynamically linked to the version of OpenSSL on the system). @p{par}
