+CHANGELOG
+=========
+
+2.6.0
+-----
+
+ * deprecated OptionsResolverInterface
+ * [BC BREAK] removed "array" type hint from OptionsResolverInterface methods
+ setRequired(), setAllowedValues(), addAllowedValues(), setAllowedTypes() and
+ addAllowedTypes()
+ * added OptionsResolver::setDefault()
+ * added OptionsResolver::hasDefault()
+ * added OptionsResolver::setNormalizer()
+ * added OptionsResolver::isRequired()
+ * added OptionsResolver::getRequiredOptions()
+ * added OptionsResolver::isMissing()
+ * added OptionsResolver::getMissingOptions()
+ * added OptionsResolver::setDefined()
+ * added OptionsResolver::isDefined()
+ * added OptionsResolver::getDefinedOptions()
+ * added OptionsResolver::remove()
+ * added OptionsResolver::clear()
+ * deprecated OptionsResolver::replaceDefaults()
+ * deprecated OptionsResolver::setOptional() in favor of setDefined()
+ * deprecated OptionsResolver::isKnown() in favor of isDefined()
+ * [BC BREAK] OptionsResolver::isRequired() returns true now if a required
+ option has a default value set
+ * [BC BREAK] merged Options into OptionsResolver and turned Options into an
+ interface
+ * deprecated Options::overload() (now in OptionsResolver)
+ * deprecated Options::set() (now in OptionsResolver)
+ * deprecated Options::get() (now in OptionsResolver)
+ * deprecated Options::has() (now in OptionsResolver)
+ * deprecated Options::replace() (now in OptionsResolver)
+ * [BC BREAK] Options::get() (now in OptionsResolver) can only be used within
+ lazy option/normalizer closures now
+ * [BC BREAK] removed Traversable interface from Options since using within
+ lazy option/normalizer closures resulted in exceptions
+ * [BC BREAK] removed Options::all() since using within lazy option/normalizer
+ closures resulted in exceptions
+ * [BC BREAK] OptionDefinitionException now extends LogicException instead of
+ RuntimeException
+ * [BC BREAK] normalizers are not executed anymore for unset options
+ * normalizers are executed after validating the options now
+ * [BC BREAK] an UndefinedOptionsException is now thrown instead of an
+ InvalidOptionsException when non-existing options are passed
