About This Chart

This Zcash release schedule represents the current plan for upcoming zcashd releases as well as historical release dates. The chart is chronological, representing past to future from left to right. The vertical axis is used only for layout without other meaning.

Each release is represented as a rectangle whose left side corresponds to the release date when Electric Coin Company plans to release official source and binary packages for all supported platforms. The right side represents the anticipated end-of-support halt date when the node will shut down, which is approximately 16 weeks after the release date.

The releases are color-coded corresponding to the mainnet protocol those releases support, which also correlates to the first number in the release. Currently defined protocol release series are:

  • the 2.x Blossom zcashd release series (NU2),
  • the 3.x Heartwood zcashd release series (NU3),
  • the 4.x Canopy zcashd release series (NU4),
  • and the 5.x NU5 zcashd release series

The current date is represented as a red dot on the horizontal timeline. Activation dates for past protocol upgrades are represented as dashed vertical lines and for future upgrades, are represented as anticipated activation windows.
