[Unreleased]

[0.1.229] - 2026-11-12

• Add the defclosedrecord option :value-type true. It defines the record as a value class through value-type (org.hugoduncan/value-type 0.1.127 or later, which must be on the class path). A value record:

  • has only its declared fields and no metadata, so a record with at most 64 bits of fields can flatten;
  • throws at read for a map literal with an undeclared key;
  • is non-nil in each field that has ^:non-nil metadata and a class tag.

  clojure.walk/macroexpand-all of a value record throws value-type :not-installed. See doc/value-type-records.md.

[0.1.190] - 2026-10-29

• Add defclosedrecord, a record that rejects undeclared keys and prevents removal of declared keys.
