Wait until it has completelyshut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)or `bitcoind`/`bitcoin-qt` (on Linux).The first time you run version 0.15.0 or higher, your chainstate database willbe converted to a new format, which will take anywhere from a few minutes tohalf an hour, depending on the speed of your machine.The file format of `fee_estimates.dat` changed in version 0.15.0. Hence, adowngrade from version 0.15 or upgrade to version 0.15 will cause all feeestimates to be discarded.Note that the block database format also changed in version 0.8.0 and there is noautomatic upgrade code from before version 0.8 to version 0.15.0. Upgradingdirectly from 0.7.x and earlier without redownloading the blockchain is not supported.However, as usual, old wallet versions are still supported.Downgrading warning-------------------The chainstate database for this release is not compatible with previousreleases, so if you run 0.15 and then decide to switch back to anyolder version, you will need to run the old release with the `-reindex-chainstate`option to rebuild the chainstate data structures in the old format.If your node has pruning enabled, this will entail re-downloading andprocessing the entire blockchain.Compatibility==============Bitcoin Core is extensively tested on multiple operating systems usingthe Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.Bitcoin Core should also work on most other Unix-like systems but is notfrequently tested on them.Notable changes===============Denial-of-Service vulnerability CVE-2018-17144-------------------------------A denial-of-service vulnerability exploitable by miners has been discovered inBitcoin Core versions 0.14.0 up to 0.16.2. It is recommended to upgrade any ofthe vulnerable versions to 0.15.2 or 0.16.3 as soon as possible.0.15.2 Change log=================### Build system- #11995 `9bb1a16` depends: Fix Qt build with XCode 9.2(fanquake)- #12946 `93b9a61` depends: Fix Qt build with XCode 9.3(fanquake)- #13544 `9fd3e00` depends: Update Qt download url (fanquake)- #11847 `cb7ef31` Make boost::multi_index comparators const (sdaftuar)### Consensus- #14247 `4b8a3f5` Fix crash bug with duplicate inputs within a transaction (TheBlueMatt, sdaftuar) ### RPC- #11676 `7af2457` contrib/init: Update openrc-run filename (Luke Dashjr)- #11277 `7026845` Fix uninitialized URI in batch RPC requests (Russell Yanofsky) ### Wallet- #11289 `3f1db56` Wrap dumpwallet warning and note scripts aren't dumped (MeshCollider)- #11289 `42ea47d` Add wallet backup text to import*, add* and dumpwallet RPCs (MeshCollider)- #11590 `6372a75` [Wallet] always show help-line of wallet encryption calls (Jonas Schnelli)### bitcoin-tx- #11554 `a69cc07` Sanity-check script sizes in bitcoin-tx (TheBlueMatt)### Tests- #11277 `3a6cdd4` Add test for multiwallet batch RPC calls (Russell Yanofsky)- #11647 `1c8c7f8` Add missing batch rpc calls to python coverage logs (Russell Yanofsky)- #11277 `1036c43` Add missing multiwallet rpc calls to python coverage logs (Russell Yanofsky)- #11277 `305f768` Limit AuthServiceProxyWrapper.\_\_getattr\_\_ wrapping (Russell Yanofsky)- #11277 `2eea279` Make AuthServiceProxy.\_batch method usable (Russell Yanofsky)Credits=======Thanks to everyone who directly contributed to this release:- fanquake- Jonas Schnelli- Luke Dashjr- Matt Corallo- MeshCollider- Russell Yanofsky- Suhas Daftuar- Wladimir J. van der LaanAnd to those that reported security issues:- awemany (for CVE-2018-17144, previously credited as "anonymous reporter")
