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. Should also work on most other Unix-like systems but is not frequently tested on them.
