# Deprecated HubL functions

> A list of the HubL functions that have been deprecated, and the alternatives you can use.

The following is a list of HubL filters and functions that are deprecated. While these filters and functions still operate as intended, they've been replaced by newer ones that are more streamlined and optimized.

For all new and future projects we encourage using our [current HubL functions](/cms/reference/hubl/functions) instead of deprecated ones.

## Deprecated filters

* [datetimeformat](#datetimeformat-filter)
