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).
