1 Optional Integer NA Support Pandas has gained the ability to hold integer dtypes with missing values. This long requested feature is enabled through the use of extension types. Note: IntegerArray is will infer to integer dtype. The display of the Series will also use the NaN to indicate missing values in string outputs. (GH20700, GH20747, GH22441, GH21789, GH22346) ```python In [1]: s = pd.Series([1 may be changed at a future date. See Nullable Integer Data Type for more. ## 1.1.2 Accessing the values in a Series or Index Series.array and Index.array have been added for extracting the array backing

Servlet ModelAndView and View objects as handler method return values * default attribute names for annotated handler method return values are consistently derived from the declared type * added & ^{*} $ BeanWrapperImpl trims an enum candidate value before matching it against the available enum values $ ^{*} $ BeanWrapperImpl resolves the target type for a generically typed bean property, performing any) * PropertyOverrideConfigurer is able to properly override target bean definitions behind a scoped proxy decorator * added "nullValue" property to PropertyPlaceholderConfigurer, allowing

CustomizableTraceInterceptor properly escapes all "\" and "$" symbols in replacement values Package org.springframework.beans * revised GenericTypeAwarePropertyDescriptor for compatibility JDK 1.6 (avoiding NPE) * TypeMismatchException shows type description for mismatching JDK proxy values (listing their implemented interfaces) * CustomNumberEditor explicitly removes all inline whitespace HandlerMethodInvoker does not eagerly copy entire model Map in order to avoid lazy initialization of attribute values $ ^{*} $ Servlet AnnotationMethodHandlerAdapter throws ambiguity exception in case of equivalent

FreeMarker "formSingleSelect" macro also accepts options from a sequence (list) as both labels and values Package org.springframework.validation * clarified that BindingResult's "getPropertyEditorRegistry()" detects session-scoped JSTL LocalizationContext/Locale attributes and merges them with its own context * JstlView and (JspAware)RequestContext consistently use JSTL Config class for scoped attribute access "type" attribute into "method", accepting strongly typed @RequestMappingMethod enum values * revised AnnotationMethodHandlerAdapter's resolution of multiple matching handler methods to
