Notable changes

Removal of Fee Estimation

The estimatefee RPC call, which estimated the fee needed for a transaction to be included within a target number of blocks, has been removed. The fee that should be paid under normal circumstances is the ZIP 317 conventional fee; it is not possible to compute that without knowing the number of logical actions in a transaction, which was not an input to estimatefee. The fee_estimates.dat file is no longer used.

Platform Support

• Ubuntu 18.04 LTS has been removed from the list of supported platforms. It reached End of Support on May 31st 2023, and no longer satisfies our Tier 2 policy requirements.
