Mandatory Update

ION Core v3.1.0 is a mandatory update for all users. This release contains new consensus rules and improvements that are not backwards compatible with older versions. Users will have a grace period of one week to update their clients before enforcement of this update is enabled.

The new Spork Key implementation is scheduled for GMT: Thursday, 7. February 2019 00:00:01.
The old Spork key will be rejected GMT: Wednesday, 13. February 2019 00:00:01. Users must upgrade prior to this time.

Users updating from a previous version after GMT: Wednesday, 13. February 2019 00:00:01 will require a full resync of their local blockchain from either the P2P network or by way of bootstrap.

How to Upgrade

Shut down old client, ensure the shutdown process has completed fully (this process may take some time). Find the appropriate installer/files for your OS at: https://github.com/ioncoincore/ion/releases On Windows: Run the installer for version 3.1.x. MacOS: Copy the new ionQT to /Applications/ION-Qt Linux: Replace iond/ion-qt (on Linux).

Compatibility

ION Core is extensively tested on multiple operating systems using
the Linux kernel, macOS 10.8+, and Windows Vista and later.

Microsoft ended support for Windows XP on April 8th, 2014,
No attempt is made to prevent installing or running the software on Windows XP, you
can still do so at your own risk but be aware that there are known instabilities and issues.
Please do not report issues about Windows XP to the issue tracker.

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

xION Updates

xION Staking

xION Staking is here! xION staking will be activated on the morning of the Sunday, 6. January 2019 00:00:01.
With the release of xION staking, there are effectively 2 versions of xION, xION minted on the 3.0.6 ION wallet or lower, and xION minted on ION 3.1.x wallet version or higher.
New features in this release will require the use of xION v2, xION minted on this wallet release 3.1.x or later. If you currently hold xION v1 and wish to take advantage of xION staking and deterministic xION, you will need to redeem the xION v1 to yourself and remint xION v2.
Note: To find your xION version, click the privacy tab, then the xION Control button then expand the arrows next to the desired denomination.

Deterministic xION Seed Keys

xION is now associated with a deterministic seed key. With this seed key, users are able to securely backup their xION, and restore to another wallet. xION can also be transferred from wallet to wallet without the need of transferring the wallet data file.

Updated xION minting

xION minting now only requires 1 additional mint (down from 2) to mature. xION mints still require 20 confirmations. Mints also require that the 'second' mint is at least two checkpoints deep in the chain (this was already the case, but the logic was not as precise).

xION Search

Users will now have the ability to search the blockchain for a specific serial # to see if a xION denomination has been spent or not.
