+### Switching between Ripgrep mode and fzf mode using a single key binding
+
+In contrast to the previous version, we use just one hotkey to toggle between
+ripgrep and fzf mode. This is achieved by using the `$FZF_PROMPT` as a state
+within the `transform` action, a feature introduced in [fzf 0.45.0][0.45.0]. A
+more detailed explanation of this feature can be found in a previous section -
+[Toggling with a single keybinding](#toggling-with-a-single-key-binding).
+
+[0.45.0]: https://github.com/junegunn/fzf/blob/master/CHANGELOG.md#0450

+When using the `transform` action, the placeholder (`\{q}`) should be escaped to
+prevent immediate evaluation.

 CHANGELOG
 =========
 
+0.46.0
+------
+- Added two new events
+    - `result` - triggered when the filtering for the current query is complete and the result list is ready
+    - `resize` - triggered when the terminal size is changed
+- fzf now exports the following environment variables to the child processes
+  | Variable           | Description                                                 |
+  | ---                | ---                                                         |
+  | `FZF_LINES`        | Number of lines fzf takes up excluding padding and margin   |
+  | `FZF_COLUMNS`      | Number of columns fzf takes up excluding padding and margin |
+  | `FZF_TOTAL_COUNT`  | Total number of items                                       |
+  | `FZF_MATCH_COUNT`  | Number of matched items                                     |
+  | `FZF_SELECT_COUNT` | Number of selected items                                    |
+  | `FZF_QUERY`        | Current query string                                        |
+  | `FZF_PROMPT`       | Prompt string                                               |
+  | `FZF_ACTION`       | The name of the last action performed                       |
+  - This allows you to write sophisticated transformations like so
+    ```sh
+    # Script to dynamically resize the preview window
+    transformer='
+      # 1 line for info, another for prompt, and 2 more lines for preview window border
+      lines=$(( FZF_LINES - FZF_MATCH_COUNT - 4 ))
+      if [[ $FZF_MATCH_COUNT -eq 0 ]]; then
+        echo "change-preview-window:hidden"
+      elif [[ $lines -gt 3 ]]; then
+        echo "change-preview-window:$lines"
+      elif [[ $FZF_PREVIEW_LINES -ne 3 ]]; then
+        echo "change-preview-window:3"
+      fi
+    '
+    seq 10000 | fzf --preview 'seq {} 10000' --preview-window up \
+                    --bind "result:transform:$transformer" \
+                    --bind "resize:transform:$transformer"
+    ```
+  - And we're phasing out `{fzf:prompt}` and `{fzf:action}`
+- Changed [mattn/go-runewidth](https://github.com/mattn/go-runewidth) dependency to [rivo/uniseg](https://github.com/rivo/uniseg) for accurate results
+    - Set `--ambidouble` if your terminal displays ambiguous width characters (e.g. box-drawing characters for borders) as 2 columns
+    - `RUNEWIDTH_EASTASIAN=1` is still respected for backward compatibility, but it's recommended that you use this new option instead
