Minor updates involving cosmetic changes have been omitted from this list. See https://github.com/cowwoc/requirements.java/commits/master for a full list.

Version 9.0.0 - 2024/05/23

• Breaking changes:
  1. The library now requires JDK 21.
  2. Added a jackson module to validate JsonNode.
  3. Removed the Maven plugin and code generator.
     • The code generator was causing a "split package" issue because it was generating code into the same package in all dependent libraries.
     • This caused a “split package” error since only one module is allowed to export a package.
  4. Removed the use of native binaries. Colored DIFFs are still supported, but Windows requires the use of Windows Terminal (free download in Windows 10, built-in feature in Windows 11).
  5. Replaced validateThat() with checkIf().
  6. Replaced assertThat() with assert assumeThat().elseThrow().
  7. Added support for the built-in assert mechanism.
     • Asserts can be used with any type of validator, but are typically used with assumeThat().orElseThrow() and checkIf().orElseThrow().
  8. Use consistent parameter ordering across the entire API: (value, name)
     • Adding contextual information now looks like this: requireThat().withContext(value, name)
  9. Added Validator.apply(Consumer) to nest validations, and Validator.and(Validator) to combine validation results.
  10. Renamed Validator.getActual() to getValue().
  11. Replaced isBetweenClosed(min, max) with isBetween(min, true, max, true).
  12. Renamed StringValidator.isInteger() to asPrimitiveInteger() and isCharacter() to asPrimitiveCharacter().
  13. Improved performance by reducing memory allocation and the frequency of GC runs.
  14. Added support for primitive types to avoid boxing when possible.
  15. Dropped the isOneOf() and isNotOneOf() functionality yet again. I haven't figured out a good design for this yet.
  16. Added ObjectValidator.isX() methods to downcast to known types.
  17. Replaced thread context with Validators.getContext(), withContext(), removeContext().
  18. Added StringValidator.matches(regex).
• Bugfixes:
  • StringValidator/Verifier.asShort(), asInteger() and asLong() were not handling the case where a string could not be converted to a number.
  • Validators were only returning the first failure.

Version 8.0.10 - 2023/06/24

• Improvements:
  • Added CollectionValidator/Verifier.doesNotContainMixedNulls().

Version 8.0.9 - 2023/06/08

• Improvements:
  • Added StringValidator/Verifier.asShort(), asInteger(), asLong() and asBigDecimal().
  • Removed unused imports in the generated API files.

Version 8.0.8 - 2023/06/08

• Skipped due to deployment error

Version 8.0.7 - 2023/04/18

• Bugfixes
  • StringValidator.length(l -> l.isBetweenClosed(min, max)) was not throwing an exception on failure.

Version 8.0.6 - 2023/04/18

• No changes (deployed by mistake)

Version 8.0.5 - 2022/10/04

• Bugfixes
  • Configuration.toString(Map) did not print out the correct values.
  • The lock field of optimized exceptions is now transient.

Version 8.0.4 - 2022/10/04

• Improvements:
  • cleanStackTrace no longer strip public library methods that invoke user code (e.g. assertThat).

Version 8.0.3 - 2022/09/28

• Improvements:
  • Added StringValidator/Verifier.strip() and isStripped().
  • Added @CheckReturnValue to ObjectValidator/Verifier.getActual().

Version 8.0.2 - 2022/09/22

• Improvements:
  • Replaced use of synchronized keyword with StampedLock to improve compatibility with virtual threads.

Version 8.0.1 - 2022/09/18

• Improvements:
  • Instantiate exceptions 3% faster by using LambdaMetafactory instead of MethodHandle.invokeExact().
  • Updated list of 3rd-party licenses.
  • Updated look of documentation on Github (minor formatting changes).

Version 8.0.0 - 2022/09/18

• Breaking changes:
  • Replaced Requirements.assertThat(actual, name) by assertThat(requirements -> requirements.requireThat(actual, name)) and assertThatAndReturn(requirements -> requirements.requireThat(actual, name)). The latter is used for assertions with a return value. This change improves the runtime performance of assertThat() and reduces code duplication across the library.
  • Replaced ThreadRequirements.getContextMessage() by DefaultRequirements.getContextMessage().
  • Removed Object.isActualAvailable() in favor of Requirements.assertionsAreEnabled().
• Bugfixes:
  • DefaultRequirements was not thread-safe.
• Improvements
  • Added Configuration-related methods (except for withoutContext() and withoutAnyContext() which wouldn't have any effect) to DefaultRequirements.

Version 7.0.4 - 2022/08/22

• Improvements
  • Updated dependencies

Version 7.0.3 - 2022/07/17

Version 7.0.1 - 2022/07/11

• Bugfix: Fixed regression that prevented ThreadRequirements from being thread-safe.

Version 7.0.0 - 2022/07/05

• Breaking changes
  • Removed thread-safety from most classes for performance-reasons. It seems like single-threaded usage is far more common.
  • Removed deprecated methods Configuration.putContext(), Configuration.removeContext() that were replaced by Configuration.withContext() and Configuration.withoutContext(), respectively.
  • Removed deprecated methods ThreadRequirements.putContext(), ThreadRequirements.removeContext(), ThreadRequirements.removeAllContext() that were replaced by ThreadRequirements.withContext(), ThreadRequirements.withoutContext() and ThreadRequirements.withoutAnyContext(), respectively.
• Improvements
  • Added default string converter for Set, Map and Throwable.
  • ArrayValidator: avoid converting array into a list until absolutely necessary.
  • Added Configuration.getContextMessage() and ThreadRequirements.getContextMessage().
  • Added Configuration.copy().
  • Added Configuration.withoutAnyContext().

• Deprecations
  • Warn that StringVerifier/Validator.asString() are no-op operations.
• Breaking changes
  • Increased minimum JDK version from 11 to 17.
  • Renamed com.github.cowwoc.requirements.annotations to com.github.cowwoc.requirements.annotation. You shouldn't need to change your source code, but the project will need to be rebuilt.

Version 6.0.4 - 2020/04/23

• Bugfixes
  • When list elements were unequal, but had the same string value, their types were not being compared.

Version 6.0.3 - 2020/04/19

• Improvements
  • If a failure message is longer than the terminal width, push the expected value from the failure message to the exception context. This helps failure messages remain readable in the face of long values.
  • Added GlobalConfiguration.getTerminalWidth(), withDefaultTerminalWidth(), withTerminalWidth().

Version 6.0.1 - 2020/04/15

• Improvements
  • Improved diff output for lists, multiline strings.

Version 6.0.0 - 2020/03/30

Version 5.2.2 - 2019/09/18

• Bugfixes
  • cleanStackTrace() was not being enforced if Throwable.printStackTrace(PrintWriter) was invoked.

Version 5.2.1 - 2019/08/31

• Bugfixes
  • ValidationFailureImpl.createMessageWithContext() was throwing NullPointerException if the context contained an empty line.

Version 5.2.0 - 2019/08/11

• Breaking changes
  • Removed PrimitiveArrayVerifier.
• Bugfixes
  • PrimitiveArrayVerifier.isNull(), isNotNull() was incorrectly showing up as deprecated.

Version 5.1.2 - 2019/07/29

• New features
  • Added ClassValidator.isSubtypeOf().
• Improvements
  • Configuration.putContext() now retains the order in which entries were inserted into the map. Note that insertion order is not affected if a key is re-inserted into the map.
  • ValidationFailure.getMessage() now includes the failure context.
  • asUri(), asUrl(), asInetAddress() now mention the actual value's expected type when it is null.
• Bug fixes
  • Multi-line diffs were sometimes incrementing line numbers when they shouldn't have.
  • Multi-line diffs were sometimes treating changed lines as duplicates.
  • asString() no longer fails if value is null. Instead, it converts the value to "null".

Version 5.1.1 - 2019/07/22

• Improvements
  • Textual diffs now use '+' for characters that needs to be added, '-' for characters that needs to be removed, and ' ' for identical characters. End of stream is marked with \0 even for single-line diffs.
  • Optimize thrown IOExceptions (improves efficiency when the stack trace is not consumed).
• Bug fixes
  • isPositive() was not failing for NaN.

Version 5.1.0 - 2019/07/16

• New features
  • Configuration (and all implementing Requirements) are thread-safe. Verifiers, Validators still assume single-threaded use.
• Breaking changes
  • Configuration methods now return updated configuration instead of this.
• Bug fixes
  • assertThat() was using the assertion status of MainConfiguration instead of Configuration by mistake.
  • GlobalConfiguration.isCleanStackTrace() was being ignored.

Version 5.0.0 - 2019/07/10

• New features

  • Added Requirements.validateThat(), an entry-point that aggregates multiple errors before returning feedback to the user.

• Breaking changes

  • Verifiers now assume single-threaded use. This allows us to make some performance optimizations at the cost of thread-safety.
  • Removed Configuration.getException(), withException(), withDefaultException() because they don't allow users to throw checked exceptions and removing them simplified the implementation. Users wishing to override the exception type should catch and wrap the thrown exception.
  • Replaced ObjectVerifier.getActualIfPresent() with getActual() and isActualAvailable() because the previous API could not differentiate between null and the value not being present.
  • length(Consumer<PrimitiveNumberVerifier<Integer>) and size(Consumer<PrimitiveNumberVerifier<Integer>) now take a Consumer<SizeVerifier> argument.
  • Renamed GlobalRequirements.isLibraryRemovedFromStackTrace() to cleanStackTrace().
  • Moved annotations from org.bitbucket.cowwoc.requirements.java.annotations to org.bitbucket.cowwoc.requirements.annotations.
  • Renamed ApiGenerator.apply() to writeTo().

• Bug fixes

  • CollectionVerifier<T>.isNotEqualTo(Object value) should return true when value is not of type <T> (as opposed to throwing an exception).
  • Improved diff color scheme for IntelliJ IDEA.
  • Don't diff booleans.
  • Terminal.setEncodingImpl() wasn't actually setting the encoding unless the platform was Windows.

Version 4.0.6-RC - 2019/03/06

• Breaking changes
  • Removed Configuration.getConfiguration()

Version 4.0.5-RC - 2019/03/06

• New features
  • Java 11 support.
  • Added Object.isNotInstanceOf().
  • Added ThreadRequirements to specify contextual information on a thread-local level.
• Breaking changes
  • All method parameters except for addContext() order their parameters as (value, name). This is the original method ordering from version 3.x.
    • Here is a regular expression to help automate the change. It isn't perfect (so be sure to review the changes) but it will handle most cases.
    • Replace: requireThat\("(.+?)", (.+?)\)\.
    • With : requireThat($2, "$1").
  • Renamed Requirements to DefaultRequirements and Verifiers to Requirements. You should be statically importing DefaultRequirements from now on, and instantiate Requirements if you wish to override the default configuration.
  • Renamed GlobalConfiguration to GlobalRequirements.
  • ComparableVerifier.isBetween() now expects an exclusive upper-bound. Please use ComparableVerifier.isBetweenClosed() for the old functionality (when you need an inclusive upper-bound).
  • Renamed groupId from org.bitbucket.cowwoc to org.bitbucket.cowwoc.requirements. artifactId has also changed slightly.
  • Verifier methods that always return true or false are now @Deprecated and throw an exception explaining why the method should not be invoked.
  • Removed deprecated TerminalEncoding.detect() method.
  • Renamed GlobalConfiguration.getAvailableTerminalEncodings() to listTerminalEncodings().
  • Renamed GlobalConfiguration.apiInStacktrace() to removeLibraryFromStacktrace().
  • Renamed Object.isIn() to isOneOf(), isNotIn() to isNotOneOf().

Version 4.0.0-RC - 2017/07/30

• Breaking changes
  • Swapped order of the name and value parameters for all methods except addContext(). All methods now take parameters in the same order: (name, value)
    • Here is a regular expression to help automate the change:
    • Replace: requireThat\((.+?), "(.+?)"\)\.
    • With : requireThat("$2", $1).
  • Methods isEquals(), isNotEquals() now compare to Object instead of T.
    • This enables requireThat("actual", someInteger).isEqualTo(someNumber) which was previously not possible.
  • Textual diff omits "Diff" if lines are identical.
  • Removed Configurable.addContext(String key, Supplier<String> value).
  • Configurable.getContext() is now @Beta because the return type might change in the future.
• New features
  • Added Configurable.withStringConverter(), withoutStringConverter().
  • Added verifiers for char values.
• Bugfixes
  • If actual != expected but the String representations were equal, the output should have contained the actual value, but did not.

  • Added InetAddressVerifier.isIpV4(), InetAddressVerifier.isIpV6().
  • Added OptionalVerifier.contains().
  • Added ArrayVerifier.asCollection() and CollectionVerifier.asArray().
  • Added support for ANSI colors under Windows 10 build 14931 (and later) but this requires the use of a native library
  • Added support for ANSI 24-bit colors for platforms that support it.
• Breaking changes
  • Separated project into requirements-core module for Core JDK classes and requirements-guava for Guava classes.
  • Replaced AssertionVerifier and RequirementVerifier by Verifiers. The neat thing about this class is that it exposes different functionality based on the modules present on the compiler classpath.
  • Any method that returns a new verifier (e.g. MapVerifier.keySet()) is expected to provide an overload that consumes the verifier instead of returning it. This mechanism replaces ObjectVerifier.isolate() which has been removed.
  • Renamed MultimapVerifier.entrySet() to MultimapVerifier.entries()
  • Removed StringVerifier.isEmailFormat() because it wasn't adding sufficient value (there is no good way to validate emails offline).

• Bugfixes
  • ANSI colors outputted on Windows 10 versions that did not support it; fixed.
  • Collection.size().isIn(Range), Map.size().isIn(Range) and String.length().isIn(Range) were outputting unicode characters; fixed.
  • ComparableRequirementsImpl.isGreaterthanOrEqualTo() was outputting the wrong parameter name.
