Notable changes

RPC Changes

• getdeprecationinfo has several changes:
  • It now returns additional information about currently deprecated and disabled features.
  • A new end_of_service object that contains both the block height for end-of-service and the estimated time that the end-of-service halt is expected to occur. Note that this height is just an approximation and will change over time as the end-of-service block height approaches, due to the variability in block times. The end_of_service object is intended to replace the deprecationheight field; see the Deprecations section for additional detail.
  • This RPC method was previously only available for mainnet nodes; it is now also available for testnet and regtest nodes, in which case it does not return end-of-service halt information (as testnet and regtest nodes do not have an end-of-service halt feature.)
• Several z_sendmany failures have moved from synchronous to asynchronous, so while you should already be checking the async operation status, there are now more cases that may trigger failure at that stage.

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:

• deprecationinfo_deprecationheight: The deprecationheight field of getdeprecationinfo has been deprecated and replaced by the end_of_service object.
