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.)

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.
