# Breaking: #106118 - Property DataHandler->storeLogMessages removed {#breaking-106118-1738942498}

See [forge#106118](https://forge.typo3.org/issues/106118)

## Description {#description}

The public property
`\TYPO3\CMS\Core\DataHandling\DataHandler->storeLogMessages` has
been removed without substitution. It should no longer be used by extensions.

## Impact {#impact}

Setting or reading the property in an extension will now raise a PHP warning-
level error.

## Affected installations {#affected-installations}

Instances with extensions that access this property are affected. This should
be a very rare use case. No TYPO3 Extension Repository (TER) extensions were
affected during verification. The extension scanner is configured to find
usages as a weak match.

## Migration {#migration}

The property has been removed. Any code setting or reading it from
`\TYPO3\CMS\Core\DataHandling\DataHandler` instances should be removed. The
`DataHandler->log()` method now always writes the given `$details`
to the `sys_log` table.
