# Deprecation: #78650 - TemplateService->splitConfArray {#deprecation-78650}

See [forge#78650](https://forge.typo3.org/issues/78650)

## Description {#description}

The method `TemplateService->splitConfArray` which has been used for building the "optionSplit"
functionality has been marked as deprecated.

The method is now moved to a new class called `TypoScriptService`, effectively removing the
dependency on `$TSFE->tmpl` within a ContentObject.

## Impact {#impact}

Calling `TemplateService->splitConfArray` will throw a deprecation warning.

## Affected Installations {#affected-installations}

Any installation using an extension that calls this method.

## Migration {#migration}

Use the new method `TypoScriptService->explodeConfigurationForOptionSplit` instead.
