# Important: #88158 - Replaced moment.js with luxon

See [forge#88158](https://forge.typo3.org/issues/88158)

## Description

The JavaScript library `luxon` is added to TYPO3 as a replacement for `moment.js`
that is [declared legacy](https://momentjs.com/docs/#/-project-status/). All code shipped by TYPO3 is migrated to `luxon`.

Albeit shipped `moment.js` is not considered being public API, it is worth
mentioning that said library is removed with TYPO3 v12.1.
