1.1.2

• Exclude clojure.core/Inst to avoid warnings in Clojure 1.9 alphas

1.1.1

• Fix (at least some) AOT issues around PSimpleCell/SimpleVCell, by replacing with atom/AtomicReference.

1.1.0

• *Deprecate schema.experimental.generators and schema.experimental.complete. Find them in their new home in the separate schema-generators project.
• BREAKING change the internal details of collection specs (should only be an issue for custom collection schemas that don't rely on helpers one-element or all-elements).
• Fix generation for sequence schemas containing a non-trailing s/optional element.

1.0.6

• Install a pprint method that uses the explain, in addition to an ordinary print-method. Should fix large prints and stack overflows while pprinting schemas, or with plugins such as pretty.

1.0.5

• Fix completion through non-map collections

1.0.4

• Attempt to resolve issues with AOT compilation by moving typehint on use-fn-validation var to callsites.
• Update generators, bump minimum version of test.check to 0.9.0. Generators will only work under Clojure 1.7.0+.

• Add constrained schema for postconditions (replaces (both x (s/pred ...)))

1.0.1

• Catch and report exceptions in guards the same as preconditions, rather than allowing them to propagate out.

1.0.0

• New schema backend, which is faster, simpler, and more declarative, enabling more applications and simplifying tooling. Users of built-in schema types should experience very little or no breakage, but tooling or custom schema types will need to be updated. As a concrete example of an application that's enabled, schema now experimentally supports test-check style generation from schemas, as well as completion of partial inputs.
• BREAKING Changes to the core Schema protocol will break existing third-party schema tooling and schema types.
• BREAKING Records coerced to an ordinary (non-record) map schema are now converted to maps, rather than retaining their record type.
• Deprecate s/either in favor of s/cond-pre, s/conditional, or schema.experimental.abstract-map-schema. As of this release, either no longer works with coercion.
• Deprecate s/both in favor of improved s/conditional.
• Deprecate schema.core/defrecord+; moved to new schema.potemkin namespace.
• s/pred can more intelligently guess the predicate name
• record schemas can now coerce values to corresponding record types.
• New experimental abstract-map-schema that models super/subclasses as maps.
• Improved explains explains for leaf schemas, especially in Clojurescript.

0.4.4

• Fix ClojureScript warnings about map->Record constructors being redefined.
• Add queue schemas
• Configurable maximum length for values in error messages
• Fix potential memory leaks after many redefinitions of s/defn or s/defrecord.

0.4.3

• Fix longstanding AOT compilation issue when used with Clojure 1.7.0-RC1 and later.

0.4.2

• Add recursive schema support for ClojureScript
• Add ns metadata to defschema

0.4.1

• Fix some harmless warnings when using Schema with the latest version of ClojureScript (due to the addition of positional constructors for deftype).

0.4.0

• BREAKING Remove support for old ^{:schema ..} style annotations. :- schema is the preferred way, but metadata-style schemas are still allowed for valid Clojure typehints.
• BREAKING Remove support for bare :- Protocol annotations (use :- (s/protocol Protocol) instead).
• BREAKING Remove deprecated macros (defn, defrecord, etc) from schema.macros. The identical versions in schema.core remain.
• BREAKING Remove potemkin as a dependency, and the *use-potemkin* flag. To get the old behavior of potemkin defrecords, you can still bring your own potemkin and use schema.core/defrecord+ in place of schema.core/defrecord.

0.3.7

• Add coercion handler for s/Uuid from string input

0.3.6

• Support java.util.List instances as valid data for sequence schemas

0.3.5

• Make primitive schemas work better in some cases under partial AOT compilation

0.3.3

• Fix bug in defschema which clobbered metadata, breaking s/protocol in Clojure in 0.3.2.

0.3.2

• Fix s/protocol in Clojure (didn't work properly with extends created later)
• Fix ClojureScript (Closure) warning about reference to global RegExp object.
• Add set-compile-fn-validation! function to turn off emission of validation globally, and turn off emission of validation code for non- ^:always-validate functions when assert is false.

0.3.1

• Fix Clojurescript compilation warnings/errors from accidental references to clojure.data/diff and class inside error messages.

0.3.0

• BREAKING increase minimum clojurescript version 2120 to support :include-macros
• Deprecate direct use of schema.macros in client code -- prefer canonical versions in schema.core in both Clojure and ClojureScript, using :include-macros true in cljs.
• Deprecate old ^{:s schema} syntax for providing schemas.
• Deprecate *use-potemkin* flag and behavior to default to potemkin s/defrecords in Clojure; in future releases, you will have to provide your own potemkin and explicitly opt-in to this behavior.
• (Hopefully) fix issues with AOT compilation, by removing dependence on potemkin/import-vars.
• Add isa schema for Clojure hierarchies.
• Preserve the types of maps (including Records) when coercing with map schemas.
• Smarter code generation in s/defrecord to avoid dead code warnings
• Fix printed form of s/Str in ClojureScript
• Make some internal fns public to simplify third-part schema extensions
• Walking records with map schemas preserves the record type
• Proper explain for s/Str

0.2.6

• Memoize walker computation, providing much faster checker compilation for graph-structured schemas

0.2.5

• Replace cljs-test with headless clojurescript.test.

0.2.0

• breaking change: Cross-platform leaves String and Number are now Str and Num (the former caused warnings and broke AOT).
• Replaced core Schema protocol method check with walker, for increased speed and versatility
• Support for schema-driven transformations/coercion
• Schemas for primitive arrays (longs, etc)
• Schematized letfn

0.1.10

• Remove non-dev dependency on cljx

0.1.9

• Support for pre/postcondition maps in s/defn
• Support for recursive schemas in Clojure
• Fixes for sm/defn and sm/defrecord with cljs advanced compilation
