| 16 | +How to Upgrade |
| 17 | +============== |
| 18 | + |
| 19 | +If you are running an older version, shut it down. Wait until it has completely |
| 20 | +shut down (which might take a few minutes for older versions), then run the |
| 21 | +installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac) |
| 22 | +or `bitcoind`/`bitcoin-qt` (on Linux). |
| 23 | + |
| 24 | +The first time you run version 0.15.0 or higher, your chainstate database will |
| 25 | +be converted to a new format, which will take anywhere from a few minutes to |
| 26 | +half an hour, depending on the speed of your machine. |
| 27 | + |
| 28 | +The file format of `fee_estimates.dat` changed in version 0.15.0. Hence, a |
| 29 | +downgrade from version 0.15 or upgrade to version 0.15 will cause all fee |
| 30 | +estimates to be discarded. |
| 31 | + |
| 32 | +Note that the block database format also changed in version 0.8.0 and there is no |
| 33 | +automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading |
| 34 | +directly from 0.7.x and earlier without redownloading the blockchain is not supported. |
| 35 | +However, as usual, old wallet versions are still supported. |
| 36 | + |
| 37 | +Downgrading warning |
| 38 | +------------------- |
| 39 | + |
| 40 | +The chainstate database for this release is not compatible with previous |
| 41 | +releases, so if you run 0.15 and then decide to switch back to any |
| 42 | +older version, you will need to run the old release with the `-reindex-chainstate` |
| 43 | +option to rebuild the chainstate data structures in the old format. |
| 44 | + |
| 45 | +If your node has pruning enabled, this will entail re-downloading and |
| 46 | +processing the entire blockchain. |
| 47 | + |
| 48 | +Compatibility |
| 49 | +============== |
| 50 | + |
| 51 | +Bitcoin Core is extensively tested on multiple operating systems using |
| 52 | +the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported. |
| 53 | + |
| 54 | +Bitcoin Core should also work on most other Unix-like systems but is not |
| 55 | +frequently tested on them. |
| 56 | + |
| 57 | + |
| 58 | +Notable changes |
| 59 | +=============== |
| 60 | + |
| 61 | +Denial-of-Service vulnerability CVE-2018-17144 |
| 62 | +------------------------------- |
| 63 | + |
| 64 | +A denial-of-service vulnerability exploitable by miners has been discovered in |
| 65 | +Bitcoin Core versions 0.14.0 up to 0.16.2. It is recommended to upgrade any of |
| 66 | +the vulnerable versions to 0.15.2 or 0.16.3 as soon as possible. |
