+## Breaking changes:
+
+* `epix_slide` has been made more like `dplyr::group_modify`. It will no longer
+  perform element/row recycling for size stability, accepts slide computation
+  outputs containing any number of rows, and no longer supports `all_rows`.
+  * To keep the old behavior, manually perform row recycling within `f`
+    computations, and/or `left_join` a data frame representing the desired
+    output structure with the current `epix_slide()` result to obtain the
+    desired repetitions and completions expected with `all_rows = TRUE`.
+* `epix_slide` will only output grouped or ungrouped tibbles. Previously, it
+  would sometimes output `epi_df`s, but not consistently, and not always with
+  the metadata desired. Future versions will revisit this design, and consider
+  more closely whether/when/how to output an `epi_df`.
+  * To keep the old behavior, convert the output of `epix_slide()` to `epi_df`
+    when desired and set the metadata appropriately.
+
+## Improvements:
+
+* `epi_slide` and `epix_slide` now support `as_list_col = TRUE` when the slide
+  computations output atomic vectors, and output a list column in "chopped"
+  format (see `tidyr::chop`).
+* `epi_slide` now works properly with slide computations that output just a
+  `Date` vector, rather than converting `slide_value` to a numeric column.

   * Slide functions now keep any grouping of `x` in their results, like

+* Additional `epi_slide` changes:
+  * When using `as_list_col = TRUE` together with `ref_time_values` and
+    `all_rows=TRUE`, the marker for excluded computations is now a `NULL` entry

 * Additional`epix_slide` changes:
   * `epix_slide`'s `group_by` argument has been replaced by `dplyr::group_by` and
