+## Breaking changes

+- `epi_slide` interface has major breaking changes.
+  - All variables are now dot-prefixed to be more consistent with tidyverse
+    style for functions that allow tidyeval.
+  - The `before/after` arguments have been replaced with the `.window_size` and
+    `.align` arguments.
+  - `names_sep` has been removed. If you return data frames from your
+    computations:
+    - without a name, they will be unpacked into separate columns without name
+      prefixes
+    - with a name, it will become a packed data.frame-class column (see
+      `tidyr::pack`).
+  - `as_list_col` has been removed. You can now directly return a list from your
+    slide computations instead. If you were using `as_list_col=TRUE`, you will
+    need to wrap your output in a list.
+  - Ungrouped slides are no longer allowed in `epi_slide`. If you used this for
+    geographic aggregation up to national, consider using `sum_groups_epi_df`.
+  - Added `sum_groups_epi_df` to allow aggregation across key columns prior to
+    sliding.
+- `epix_slide` interface has major changes.
+  - All variables are now dot-prefixed to be more consistent with tidyverse

+    slide computations instead. If you were using `as_list_col=TRUE`, you will
+    need to wrap your output in a list.
+- `as_epi_df()` now checks that every group has unique time values and errors if
+  this is not the case. The same check is performed at the beginning of
+  `epi_slide()`. This check is currently not enforced in dplyr operations (like
+  for joins, mutates, or select), but we plan to add it in the future.
+- `as_epi_df()` or `as_epi_archive()` no longer accept `additional_metadata`.
+  Use the new `other_keys` arg to specify additional key columns, such as age
+  group columns or other demographic breakdowns. Miscellaneous metadata are no
+  longer handled by `epiprocess`, but you can use R's built-in `attr<-` instead
+  for a similar feature.
+
 ## Improvements
 
 - Added `complete.epi_df`, which fills in missing values in an `epi_df` with
   `NA`s. Uses `tidyr::complete` underneath and preserves `epi_df` metadata.
-- Inclusion of the function `revision_summary` to provide basic revision information for `epi_archive`s out of the box. (#492)
