⚠ pumpkin-core breaking changes

--- failure enum_missing: pub enum removed or renamed ---

Description:
A publicly-visible enum cannot be imported by its prior path. A `pub use` may have been removed, or the enum itself may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.51.0/src/lints/enum_missing.ron

Failed in:
  enum pumpkin_core::branching::tie_breaking::Direction, previously in file /tmp/.tmpVwQXUj/pumpkin-core/src/branching/tie_breaking/tie_breaker.rs:23
  enum pumpkin_core::branching::branchers::alternating::BrancherToUse, previously in file /tmp/.tmpVwQXUj/pumpkin-core/src/branching/branchers/alternating/strategies/mod.rs:59

--- failure enum_variant_added: enum variant added on exhaustive enum ---

Description:
A publicly-visible enum without #[non_exhaustive] has a new variant.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#enum-variant-new
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.51.0/src/lints/enum_variant_added.ron

Failed in:
  variant Priority:UltraLow in /tmp/.tmpNersLg/Pumpkin/pumpkin-crates/core/src/propagation/propagator.rs:255

--- failure inherent_method_missing: pub method removed or renamed ---

Description:
A publicly-visible method or associated fn is no longer available under its prior name. It may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.51.0/src/lints/inherent_method_missing.ron

--- failure module_missing: pub module removed or renamed ---

Description:
A publicly-visible module cannot be imported by its prior path. A `pub use` may have been removed, or the module may have been renamed, removed, or made non-public.
