zcash_primitives-0.20.0: zcash_primitives release version 0.20.0

[0.20.0] - 2024-11-14
=====================

Added
-----
- A new feature flag, `non-standard-fees`, has been added. This flag is now
  required in order to make use of any types or methods that enable non-standard
  fee calculation.

Changed
-------
- MSRV is now 1.77.0.
- `zcash_primitives::transaction::fees`:
  - The `fixed` module has been moved behind the `non-standard-fees` feature
    flag. Using a fixed fee may result in a transaction that cannot be mined on
    the current Zcash network. To calculate the ZIP 317 fee, use
    `zip317::FeeRule::standard()`.
  - `zip317::FeeRule::non_standard` has been moved behind the `non-standard-fees`
    feature flag. Using a non-standard fee may result in a transaction that cannot
    be mined on the current `Zcash` network.

Removed
-------
- `zcash_primitives::transaction::fees`:
  - `StandardFeeRule` itself has been removed; it was not used in this crate.
    Its use in `zcash_client_backend` has been replaced with
    `zcash_client_backend::fees::StandardFeeRule`.
  - `fixed::FeeRule::standard`. This constructor was misleadingly named: using a
    fixed fee does not conform to any current Zcash standard. To calculate the
    ZIP 317 fee, use `zip317::FeeRule::standard()`. To preserve the current
    behaviour, use `fixed::FeeRule::non_standard(zip317::MINIMUM_FEE)`,
    but note that this is likely to result in transactions that cannot be mined.
