+Bitcoin Core version *0.15.2* is now available from:
+
+  <https://bitcoincore.org/bin/bitcoin-core-0.15.2/>
+
+This is a new minor version release, including various bugfixes and
+performance improvements, as well as updated translations.
+
+Please report bugs using the issue tracker at GitHub:

+
+How to Upgrade
+==============
+
+If you are running an older version, shut it down. Wait until it has completely
+shut 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 will
+be converted to a new format, which will take anywhere from a few minutes to
+half an hour, depending on the speed of your machine.
+
+The file format of `fee_estimates.dat` changed in version 0.15.0. Hence, a
+downgrade from version 0.15 or upgrade to version 0.15 will cause all fee
+estimates to be discarded.
+
+Note that the block database format also changed in version 0.8.0 and there is no
+automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading
+directly 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 previous
+releases, so if you run 0.15 and then decide to switch back to any
+older 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 and
+processing the entire blockchain.
+
+Compatibility
+==============
+
+Bitcoin Core is extensively tested on multiple operating systems using
+the 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 not
+frequently tested on them.
+
+
+Notable changes
+===============
+
+Denial-of-Service vulnerability CVE-2018-17144
+-------------------------------
+
+A denial-of-service vulnerability exploitable by miners has been discovered in
+Bitcoin Core versions 0.14.0 up to 0.16.2. It is recommended to upgrade any of
+the vulnerable versions to 0.15.2 or 0.16.3 as soon as possible.
