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
