+PIVX Core version v5.2.0 is now available from:  <https://github.com/pivx-project/pivx/releases>
+
+This is a new major version release, including various bug fixes and visual improvements.
+
+Please report bugs using the issue tracker at github: <https://github.com/pivx-project/pivx/issues>
+
+Mandatory Update
+==============
+
+PIVX Core v5.2.0 is a mandatory update for all users. This release contains a protocol upgrade (to `70922`), new consensus rules and improvements that are not backwards compatible with older versions. Users will need to update their clients before enforcement of this update goes into effect.
+
+Update enforcement is currently scheduled to go into effect at the following block height:
+```
+Mainnet: 2,927,000
+```
+Masternodes will need to be restarted once both the masternode daemon and the controller wallet have been upgraded.
+
+Note: In preparation for the enforcement, upgraded peers will start rejecting non-upgraded peers few hours before the enforcement block height, we recommend everyone to be updated at max a day before the final time.
+
+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/PIVX-Qt (on Mac) or pivxd/pivx-qt (on Linux).
+
+Sapling Parameters
+==================
+
+In order to run, PIVX Core now requires two files, `sapling-output.params` and `sapling-spend.params` (with total size ~50 MB), to be saved in a specific location.
+
+For the following packages, no action is required by the user:
+- macOS release `dmg` binaries will use the params that are bundled into the .app bundle.
+- Windows installer `.exe` will automatically copy the files in the proper location.
+- Linux `PPA/Snap` installs will automatically copy the files in the proper location.
+
+For the other packages, the user must save the param files in the proper location, before being able to run PIVX v5.2.0:
+- macOS/Linux `tar.gz` tarballs include a bash script (`install-params.sh`) to copy the parameters in the appropriate location.
+- Windows `.zip` users need to manually copy the files from the `share/pivx` folder to the `%APPDATA%\PIVXParams` directory.
+- self compilers can run the script from the repository sources (`params/install-params.sh`), or copy the files directly from the `params` subdirectory.
+
+Compatibility
+==============
+
+PIVX Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.12+, and Windows 7 and later.
+
+PIVX Core should also work on most other Unix-like systems but is not frequently tested on them.
