11How to Upgrade
12
13If you are running an older version, shut it down. Wait
14until it has completely shut down (which might take a few minutes for older
15versions), then run the installer (on Windows) or just copy over
16/Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
17
18If you are upgrading from version 0.7.2 or earlier, the first time you
19run 0.8.2 your blockchain files will be re-indexed, which will take
20anywhere from 30 minutes to several hours, depending on the speed of
21your machine.
22
230.8.2 Release notes
24
25Fee Policy changes
26
27The default fee for low-priority transactions is lowered from 0.0005 BTC 
28(for each 1,000 bytes in the transaction; an average transaction is
29about 500 bytes) to 0.0001 BTC.
30
31Payments (transaction outputs) of 0.543 times the minimum relay fee
32(0.00005430 BTC) are now considered 'non-standard', because storing them
33costs the network more than they are worth and spending them will usually
34cost their owner more in transaction fees than they are worth.
35
36Non-standard transactions are not relayed across the network, are not included
37in blocks by most miners, and will not show up in your wallet until they are
38included in a block.
39
40The default fee policy can be overridden using the -mintxfee and -minrelaytxfee
41command-line options, but note that we intend to replace the hard-coded fees
42with code that automatically calculates and suggests appropriate fees in the
430.9 release and note that if you set a fee policy significantly different from
44the rest of the network your transactions may never confirm.
45

72* -par now takes a negative number, to leave a certain amount of cores free.
73
74JSON-RPC API changes
75
76* fixed a getblocktemplate bug that caused excessive CPU creating blocks.
77* listunspent now lists account and address information.
78* getinfo now also returns the time adjustment estimated from your peers.
79* getpeerinfo now returns bytessent, bytesrecv and syncnode.
80* gettxoutsetinfo returns statistics about the unspent transaction output database.
81* gettxout returns information about a specific unspent transaction output.
82
83
84Networking changes
85
86* Significant changes to the networking code, reducing latency and memory consumption.
87* Avoid initial block download stalling.
88* Remove IRC seeding support.
89* Performance tweaks.
90* Added testnet DNS seeds.
91
92Wallet compatibility/rescuing
93

96
97
98Known Bugs
99
100* Entering the 'getblocktemplate' or 'getwork' RPC commands into the Bitcoin-Qt debug
