====================

Licensing
---------
- The license for this crate is now "MIT OR Apache-2.0". The license
  exception that applied to the Zcash and Zebra projects, other projects
  designed to integrate with Zcash, and certain forks of Zcash, is no longer
  necessary. For clarity, this is intended to be a strict relaxation of the
  previous licensing, i.e. it permits all usage that was previously possible
  with or without use of the license exception.

Added
-----
- `orchard::builder`:
  - `bundle`
  - `BundleMetadata`
  - `BundleType`
  - `OutputInfo`
- `orchard::bundle::Flags::{ENABLED, SPENDS_DISABLED, OUTPUTS_DISABLED}`
- `orchard::tree::Anchor::empty_tree`

Changed
-------
- Migrated to the `zip32` crate. The following types have been replaced by the
  equivalent ones in that crate are now re-exported from there:
  - `orchard::keys::{DiversifierIndex, Scope}`
  - `orchard::zip32::ChildIndex`
- `orchard::builder`:
  - `Builder::new` now takes the bundle type to be used in bundle construction,
    instead of taking the flags and anchor separately.
  - `Builder::add_recipient` has been renamed to `add_output` in order to
    clarify than more than one output of a given transaction may be sent to the
    same recipient.
  - `Builder::build` now takes an additional `BundleType` argument that
    specifies how actions should be padded, instead of using hardcoded padding.
    It also now returns a `Result<Option<(Bundle<...>, BundleMetadata)>, ...>`
    instead of a  `Result<Bundle<...>, ...>`.
  - `BuildError` has additional variants:
    - `SpendsDisabled`
    - `OutputsDisabled`
    - `AnchorMismatch`
  - `SpendInfo::new` now returns a `Result<SpendInfo, SpendError>` instead of an
    `Option`.
- `orchard::keys::SpendingKey::from_zip32_seed` now takes a `zip32::AccountId`.

Removed
-------
- `orchard::bundle::Flags::from_parts`
