    Fluid v4.
-   Deprecation: Method `TYPO3FluidFluidViewTemplatePaths->getPackagePath()`
    has been marked as deprecated. It will log a deprecation level error message when called in
    Fluid v4.

-   Deprecation: Trait `TYPO3FluidFluidCoreViewHelperTraitsCompileWithRenderStatic`
    has been marked as deprecated. It will log a deprecation level error message when called in
    Fluid v4. It will be removed in Fluid v5.
-   Deprecation: Trait `TYPO3FluidFluidCoreViewHelperTraitsCompileWithContentArgumentAndRenderStatic`
    has been marked as deprecated. It will log a deprecation level error message when called in
    Fluid v4. It will be removed in Fluid v5.
-   Deprecation: Static method `renderStatic()` on ViewHelpers that don't use `TYPO3FluidFluidCoreViewHelperTraitsCompileWithRenderStatic`
    or `TYPO3FluidFluidCoreViewHelperTraitsCompileWithContentArgumentAndRenderStatic`
    have been marked as deprecated. They will log a deprecation level error message when called in
    Fluid v4. `renderStatic()` will no longer be called in Fluid v5.
-   Deprecation: Variable names `true`, `false` and `null` will log a deprecation level error message because these
    identifiers will become a Fluid language feature with v4.

## 2.14 {#2-14}

-   Deprecation: Method `TYPO3FluidFluidViewAbstractTemplateView::initializeRenderingContext()`
    has been marked as deprecated. It will be removed in Fluid v4.
    Migration path is to call the rendering context directly via
    `TYPO3FluidFluidViewAbstractTemplateView::getRenderingContext()->getViewHelperVariableContainer()->setView()`
-   Deprecation: Method `TYPO3FluidFluidViewAbstractTemplateView::setCache()`
    has been marked as deprecated. It will be removed in Fluid v4.
    Migration path is to call the rendering context directly via
    `TYPO3FluidFluidViewAbstractTemplateView::getRenderingContext()->setCache()`
-   Deprecation: Method `TYPO3FluidFluidViewAbstractTemplateView::getTemplatePaths()`
    has been marked as deprecated. It will be removed in Fluid v4.
    Migration path is to call the rendering context directly via
    `TYPO3FluidFluidViewAbstractTemplateView::getRenderingContext()->getTemplatePaths()`
-   Deprecation: Method `TYPO3FluidFluidViewAbstractTemplateView::getViewHelperResolver()`
    has been marked as deprecated. It will be removed in Fluid v4.
    Migration path is to call the rendering context directly via
    `TYPO3FluidFluidViewAbstractTemplateView::getRenderingContext()->getViewHelperResolver()`
-   Deprecation: Method `TYPO3FluidFluidCoreViewHelperAbstractViewHelper->overrideArgument()`
    has been marked as deprecated. It will log a deprecation level error message when called in
    Fluid v4. It will be removed in Fluid v5.
    `TYPO3FluidFluidCoreViewHelperAbstractViewHelper->registerArgument()` now no longer throws
    an exception if an argument is already defined, so calls to
    `TYPO3FluidFluidCoreViewHelperAbstractViewHelper->overrideArgument()`
    can be replaced with `TYPO3FluidFluidCoreViewHelperAbstractViewHelper->registerArgument()`.

## 2.12 {#2-12}

-   Deprecation: Method `TYPO3FluidFluidCoreViewHelperAbstractTagBasedViewHelper->registerUniversalTagAttributes()`
    has been marked as deprecated. It will log a deprecation level error message when called in
    Fluid v4. It will be removed in Fluid v5.
    Arbitrary tags are automatically added by `AbstractTagBasedViewHelper`, single ViewHelpers
    find such arguments in `$this->additionalArguments` when the call to `registerUniversalTagAttributes()`
    is removed.
-   Deprecation: Method `TYPO3FluidFluidCoreViewHelperAbstractTagBasedViewHelper->registerTagAttribute()`
    has been marked as deprecated. It will log a deprecation level error message when called in
    Fluid v4. It will be removed in Fluid v5.
    Arbitrary tags are automatically added by `AbstractTagBasedViewHelper`, single ViewHelpers
    find such arguments in `$this->additionalArguments` when the call to `registerUniversalTagAttributes()`
    is removed. Alternatively, arguments registered using `registerArgument()` can be found in
    `$this->arguments`.
-   Deprecation: Test abstracts `TYPO3FluidFluidTestsBaseTestCase` and
    `TYPO3FluidFluidTestsUnitTestCase` have been marked as deprecated and
    will be removed in Fluid v4. Extend `PHPUnitFrameworkTestCase` directly.
