v6.0.0

zend v6.0.0

Zend 6.0.0 has the same deprecation schedule as Zend 5.0.7. It is expected to deprecate on Mainnet at block #1872068, which will occur on November 13th 2025, at approximately 06:00 AM UTC.

Important Notes

This version is a release designed to support the Horizen migration by introducing the following features (implemented in #662):

• a hard fork (HF) that prevents the propagation of all transactions except coinbase transactions across the network. (Note: certificate processing will continue to function as usual.)

• the fork will activate on mainnet at block height 1807300 around 2025-07-23 04:30:00 UTC.

• the fork is active on testnet since block height 1700420, mined around 2025-06-16 08:00:00 UTC.

• a new optional configuration flag that accepts a block height value. Once the node reaches this specified height, it will cease processing any new incoming blocks.

Important Notes

Shielded pool removal

• PR #628 implements ZenIP-42207, which introduces a hard fork fully disabling the shielded pool from zend. After the hard fork, it will no longer be possible to submit and process transactions involving shielded (z-) addresses, thus transparent-to-shielded, shielded-to-shielded and shielded-to-transparent transactions will be completely disallowed.

• PR #628 as a consequence of ZenIP-42207, the following RPC commands

  • z_sendmany
  • z_mergetoaddress

  have been partially disabled, as after the hard fork they are only allowed to submit transparent-to-transparent transactions (check inline documentation for additional details).

Bugfixes and Minor Changes

• All the RPC commands interacting with the shielded pool - hence, all the RPC commands starting with z_ or zc_ (for instance z_getbalanace or zc_raw_joinsplit) - are now deprecated; a warning message has been included in the help body of these commands #628
• Fix for build error on recent compilers, including gcc v13 and clang v14, and with recent glibc (version 2.36); alignment of compiler optimization flags on clang and gcc on Linux #629
