-#' Functions renamed in phsmethods 0.2.1 (Dec 2021)
-#'
-#' @description
-#' `r lifecycle::badge('deprecated')`
-#'
-#' phsmethods 0.2.1 renamed a number of functions
-#' to improve code clarity. The old functions no longer
-#' work and will error. At the next update they will be
-#' removed completely.
-#'
-#' * `postcode()` → `format_postcode()`
-#' * `age_group()` → `create_age_groups()`
-#' * `fin_year()` → `extract_fin_year()`
