Notable changes

Fixes

This release fixes an issue that could potentially cause a node to crash with the log message "The wallet's best block hash <hash> was not detected in restored chain state. Giving up; please restart with -rescan."

RPC Changes

  • z_sendmany will no longer select transparent coinbase when "ANY_TADDR" is used as the fromaddress. It was already documented to do this, but the previous behavior didn’t match. When coinbase notes were selected in this case, they would (properly) require that the transaction didn’t have any change, but this could be confusing, as the documentation stated that these two conditions (using "ANY_TADDR" and disallowing change) wouldn’t coincide.

Deprecations

The following features have been deprecated, but remain available by default. These features may be disabled by setting -allowdeprecated=none. 18 weeks after this release, these features will be disabled by default and the following flags to -allowdeprecated will be required to permit their continued use:

  • gbt_oldhashes: the finalsaplingroothash, lightclientroothash, and blockcommitmentshash fields in the output of getblocktemplate have been replaced by the defaultroots field.

The following previously-deprecated features have been disabled by default, and will be removed in 18 weeks:

  • legacy_privacy
  • getnewaddress
  • getrawchangeaddress
  • z_getbalance
  • z_gettotalbalance
  • z_getnewaddress
  • z_listaddresses
  • addrtype
  • wallettxvjoinsplit

The following previously-deprecated features have been removed:

  • dumpwallet
  • zcrawreceive
  • zcrawjoinsplit
  • zcrawkeygen

Platform Support

  • CentOS 8 has been removed from the list of supported platforms. It reached EoL on December 31st 2021, and does not satisfy our Tier 2 policy requirements.

Daira Hopwood (6): Add tl::expected. refs #4816 The std::expected proposal has unnecessary instances of undefined behaviour for operator->, operator*, and error(). Make these into assertion failures (this still conforms to the proposal). Refactor HaveShieldedRequirements to use tl::expected (example with a void T) and rename it to CheckShieldedRequirements. tl::expected follow-up to address @str4d's comments. Cleanup after removing dumpwallet. Change the time that the wallet will wait for the block index to load from 5 minutes to 2 hours.
