 16  How to Upgrade
 17  ==============
 18  
 19  If you are running an older version, shut it down. Wait until it has
 20  completely shut down (which might take a few minutes for older
 21  versions), then run the installer (on Windows) or just copy over
 22  `/Applications/Bitcoin-Qt` (on Mac) or `bitcoind`/`bitcoin-qt` (on
 23  Linux).
 24  
 25  The first time you run version 0.15.0 or newer, your chainstate database
 26  will be converted to a new format, which will take anywhere from a few
 27  minutes to half an hour, depending on the speed of your machine.
 28  
 29  Note that the block database format also changed in version 0.8.0 and
 30  there is no automatic upgrade code from before version 0.8 to version
 31  0.15.0 or later. Upgrading directly from 0.7.x and earlier without
 32  redownloading the blockchain is not supported.  However, as usual, old
 33  wallet versions are still supported.
 34  
 35  Compatibility
 36  ==============
 37  
 38  Bitcoin Core is supported and extensively tested on operating systems
 39  using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not
 40  recommended to use Bitcoin Core on unsupported systems.
 41  
 42  Bitcoin Core should also work on most other Unix-like systems but is not
 43  as frequently tested on them.
 44  
 45  From 0.17.0 onwards, macOS <10.10 is no longer supported. 0.17.0 is
 46  built using Qt 5.9.x, which doesn't support versions of macOS older than
 47  10.10. Additionally, Bitcoin Core does not yet change appearance when
 48  macOS "dark mode" is activated.

 50  Known issues
 51  ============
 52  
 53  Wallet GUI
 54  ----------
 55  
 56  For advanced users who have both (1) enabled coin control features, and
 57  (2) are using multiple wallets loaded at the same time: The coin control
 58  input selection dialog can erroneously retain wrong-wallet state when
 59  switching wallets using the dropdown menu. For now, it is recommended
 60  not to use coin control features with multiple wallets loaded.
