differential-dataflow breaking changes

--- failure function_requires_different_generic_type_params: function now requires a different number of generic type parameters ---

Description:
A function now requires a different number of generic type parameters than it used to. Uses of this function that supplied the previous number of generic types (e.g. via turbofish syntax) will be broken.
        ref: https://doc.rust-lang.org/reference/items/generics.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.47.0/src/lints/function_requires_different_generic_type_params.ron

Failed in:
  function arrange_core (4 -> 6 generic types) in /tmp/.tmp6PRX11/differential-dataflow/differential-dataflow/src/operators/arrange/arrangement.rs:336

--- 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/v0.47.0/src/lints/inherent_method_missing.ron

Failed in:
  ShutdownButton::press_on_drop, previously in file /tmp/.tmp00yTiS/differential-dataflow/src/operators/arrange/agent.rs:489
  ShutdownButton::press_on_drop, previously in file /tmp/.tmp00yTiS/differential-dataflow/src/operators/arrange/agent.rs:489

--- 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.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove

--- failure struct_missing: pub struct removed or renamed ---

Description:
A publicly-visible struct cannot be imported by its prior path. A `pub use` may have been removed, or the struct itself may have been renamed or removed entirely.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#item-remove

--- failure trait_added_supertrait: non-sealed trait added new supertraits ---

Description:
A non-sealed trait added one or more supertraits, which breaks downstream implementations of the trait
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#generic-bounds-tighten

--- failure trait_method_requires_different_generic_type_params: trait method now requires a different number of generic type parameters ---

Description:
A trait method now requires a different number of generic type parameters than it used to. Calls or implementations of this trait method using the previous number of generic types will be broken.
        ref: https://doc.rust-lang.org/reference/items/generics.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.47.0/src/lints/trait_method_requires_different_generic_type_params.ron

Description:
A public trait's associated type was removed or renamed.

This PR was generated with release-plz.

github-actions Bot and others added 2 commits May 29, 2026 20:54
Rewrite the release-plz autogenerated 0.24.0 sections in the style of
0.23.0: split into Added / Changed / Removed / Other, expand each bullet
into a prose explanation of what actually changed, fix the garbled #725
entry (`:populate_key`), and add the timely 0.30 / columnar 0.13 bump
(bf9b36f) that release-plz missed because it landed outside a PR.
Adds a closing summary of the breaking changes downstream consumers
need to migrate.

For dogsdogsdogs, surface what Spring cleaning actually changed in its
examples (`usize::max_value()` -> `usize::MAX`) and note the timely 0.30
tracking.
