21 If you are running an older version, shut it down. Wait until it has completely
22 shut down (which might take a few minutes for older versions), then run the
23 installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
24 bitcoind/bitcoin-qt (on Linux).
26 If you are upgrading from version 0.7.2 or earlier, the first time you run

28 30 minutes to several hours, depending on the speed of your machine.
31 =======================
33 No code changes were made between 0.9.0 and 0.9.1. Only the dependencies were changed.
35 - Upgrade OpenSSL to 1.0.1g. This release fixes the following vulnerabilities which can
36 affect the Bitcoin Core software:
38 - CVE-2014-0160 ("heartbleed")
39 A missing bounds check in the handling of the TLS heartbeat extension can
40 be used to reveal up to 64k of memory to a connected client or server.
43 The Montgomery ladder implementation in OpenSSL does not ensure that
44 certain swap operations have a constant-time behavior, which makes it
45 easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache
48 - Add statically built executables to Linux build
53 Credits go to the OpenSSL team for fixing the vulnerabilities quickly.
