Hamcrest v3.0

Breaking Changes

• From version 3.0, the jar distributed to Maven Central is now compiled to Java 1.8 bytecode,
  and is not compatible with previous versions of Java. See Issue #331 and
  PR #411 for details. Developers who use Java 1.7 earlier can still depend upon hamcrest-2.2.jar.

Improvements

• FileMatchersTest simplification (PR #389)
• License cleanup (PR #414, PR #415, see also #264, #355, #396, and #399)

Java 9 module compatibility, along with numerous other improvements and bug
fixes.

Breaking Changes

Changes

• Publish a single jar hamcrest-2.1.jar
• Documentation updates
• Add implementation for CharSequence length matcher
• Fix for TypeSafeDiagnosingMatcher can't detect generic types for subclass
• Renamed IsCollectionContaining to IsIterableContaining
• Make Hamcrest an OSGI bundle
• Add StringRegularExpression matcher
• Fix StringContainsInOrder to detect if a repeated pattern is missing
• Add ArrayAsIterableMatcher
• Fix description for IsEqualIgnoringCase
• Fix JavaDoc examples
• Upgraded to Java 7
• Build with Gradle
• Publish a single jar java-hamcrest-2.0.0.0.jar

• Fix GH issue #25 - arrayContaining(null, null) cause NullPointerException
• Fix GH issue #36 - string matching on regular expressions

Hamcrest v2.1-rc4

Restore deleted classes to keep backwards compatibility with version 1.3, and mark them as deprecated.

Hamcrest v2.1-rc3

This fixes the problem that Maven has with interpreting pom-only artifacts. Both hamcrest-core and hamcrest-library artifacts now publish empty jars with a dependency on the hamcrest artifact.

Hamcrest v2.1-rc2

This release publishes pom-only artifacts for hamcrest-core and hamcrest-library for better backwards compatibility with previous releases.

Hamcrest v2.1-rc1
