13  How to Upgrade
14  ===============
15  
16  If you are running an older version, shut it down. Wait until it has completely
17  shut down (which might take a few minutes for older versions), then run the
18  installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
19  bitcoind/bitcoin-qt (on Linux).

24  Mining and relay policy enhancements
25  ------------------------------------
26  
27  Bitcoin Core's block templates are now for version 3 blocks only, and any mining
28  software relying on its `getblocktemplate` must be updated in parallel to use
29  libblkmaker either version 0.4.2 or any version from 0.5.1 onward.
30  If you are solo mining, this will affect you the moment you upgrade Bitcoin
31  Core, which must be done prior to BIP66 achieving its 951/1001 status.
32  If you are mining with the stratum mining protocol: this does not affect you.
33  If you are mining with the getblocktemplate protocol to a pool: this will affect
34  you at the pool operator's discretion, which must be no later than BIP66
35  achieving its 951/1001 status.
