v2.4.0 (2026-07-17)

• Dependency: on Clojars
• Versioning: Break Versioning

This is a minor feature and maintenance release focused on more predictable error matching, assertion behaviour, and diagnostics. It should be a safe upgrade for all typical users of v2.3.x. Please see the linked commit messages below for details.

- Peter Taoussanis

Minor behaviour changes

• matching-error's 2-arity now also matches nested causes (a loosening; some previously non-matching calls may now match).
• New compile-time validation turns previously-compiling malformed assertions like (have [:n= 2 3] x) into compile errors.
