Deprecated

As admiral is still evolving, functions/arguments may need to be removed or replaced over time. In such cases, the function/argument will enter the following 6-month deprecation cycle:

  • In the first release (0-3 months), there will be a warning issued if you use the function/argument, but it will still be available to use.
  • In the following release (3-6 months), an error will be produced if you use the function/argument.
  • Finally, from the 3rd release (6 months) onwards, the function/argument will be removed from admiral and its documentation completely.

Note: Guidance on replacement functionality can be found in the warning/error message produced or in the function’s documentation.

Below, you can find a list of functions in the process of being deprecated:
