16How to Upgrade
17==============
18
19If you are running an older version, shut it down. Wait until it has completely
20shut down (which might take a few minutes for older versions), then run the
21installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
22or `bitcoind`/`bitcoin-qt` (on Linux).
23
24The first time you run version 0.15.0 or newer, your chainstate database will be converted to a
25new format, which will take anywhere from a few minutes to half an hour,
26depending on the speed of your machine.
27
28Note that the block database format also changed in version 0.8.0 and there is no
29automatic upgrade code from before version 0.8 to version 0.15.0 or higher. Upgrading
30directly from 0.7.x and earlier without re-downloading the blockchain is not supported.
31However, as usual, old wallet versions are still supported.
32
33Downgrading warning
34-------------------
35
36Wallets created in 0.16 and later are not compatible with versions prior to 0.16
37and will not work if you try to use newly created wallets in older versions. Existing
38wallets that were created with older versions are not affected by this.
39
40Compatibility
41==============
42
43Bitcoin Core is extensively tested on multiple operating systems using
44the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.
45
46Bitcoin Core should also work on most other Unix-like systems but is not
47frequently tested on them.
48
49Notable changes
50===============
51
52Miner block size removed
53------------------------
54
55The `-blockmaxsize` option for miners to limit their blocks' sizes was
56deprecated in version 0.15.1, and has now been removed. Miners should use the
57`-blockmaxweight` option if they want to limit the weight of their blocks'
58weights.
