New ZEN software (2.0.15) is available for download today, September 28th, 2018.

All mining pools, node operators, and Swing wallet users must upgrade to ZEN 2.0.15 prior to block 392512 which will occur around midnight on October 10th.

ZEN 2.0.15 replaces the current version 2.0.14, which is set to deprecate (no longer run). The major focus is on updating the Bitcoin Consensus algorithm. This is not a hard fork.

New binaries have been released. Please update your ZEN software before October 10th. The new 2.0.15 version will be available at https://github.com/ZencashOfficial/zen/releases/latest or through the APT repository by end of day 9/27/2018.

What happens if you do not upgrade before October 10th?

Swing wallet users: You will not be able to access your funds until you upgrade to the latest Swing wallet version.
