--- failure enum_marked_non_exhaustive: enum marked #[non_exhaustive] ---

Description:
A public enum has been marked #[non_exhaustive]. Pattern-matching on it outside of its crate must now include a wildcard pattern like `_`, or it will fail to compile.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#attr-adding-non-exhaustive
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.50.0/src/lints/enum_marked_non_exhaustive.ron

Failed in:

--- failure enum_struct_variant_changed_kind: An enum struct variant changed kind ---

Description:
A pub enum's struct variant with at least one pub field has changed to a different kind of enum variant, breaking access to its pub fields.
        ref: https://doc.rust-lang.org/reference/items/enumerations.html
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.50.0/src/lints/enum_struct_variant_changed_kind.ron

--- failure method_parameter_count_changed: pub method parameter count changed ---

Description:
A publicly-visible method now takes a different number of parameters, not counting the receiver (self) parameter.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#fn-change-arity
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.50.0/src/lints/method_parameter_count_changed.ron

Failed in:
  zip::extra_fields::DataStreamAlignment::new takes 1 parameters in /tmp/.tmpmot2wZ/zip/src/extra_fields/data_stream_alignment.rs:18, but now takes 2 parameters in /tmp/.tmpMDNzwV/zip2/src/extra_fields/data_stream_alignment.rs:20
  zip::extra_fields::ExtendedTimestamp::try_from_reader takes 2 parameters in /tmp/.tmpmot2wZ/zip/src/extra_fields/extended_timestamp.rs:59, but now takes 3 parameters in /tmp/.tmpMDNzwV/zip2/src/extra_fields/extended_timestamp.rs:59

--- 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
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.50.0/src/lints/struct_missing.ron

Review Summary

This PR updates the version from 9.0.0-pre3 to 9.0.0-pre3.1 and adds corresponding changelog entries.

Critical Issue Found

There is a logic error in the release date that must be corrected before merge. The changelog entry specifies "2026-08-16" which is a future date and appears to be a typo introduced by the automated release tool (release-plz). This should be corrected to "2025-08-16" to accurately reflect the actual release date.

The version bump in Cargo.toml is correct and consistent with the changelog.
