+- Reset opts in some functions affected by `GLOB_SUBST` (#334)
+- Support widgets starting with dashes (ex: `-a-widget`) (#337)
+- Skip async tests in zsh versions less than 5.0.8 because of reliability issues
+- Fix handling of newline + carriage return in async pty (#333)
+
+

 ### Suggestion Strategy
 
-Set `ZSH_AUTOSUGGEST_STRATEGY` to choose the strategy for generating suggestions. There are currently two to choose from:
+`ZSH_AUTOSUGGEST_STRATEGY` is an array that specifies how suggestions should be generated. The strategies in the array are tried successively until a suggestion is found. There are currently two built-in strategies to choose from:
 
-- `default`: Chooses the most recent match.
-- `match_prev_cmd`: Chooses the most recent match whose preceding history item matches the most recently executed command ([more info](src/strategies/match_prev_cmd.zsh)). Note that this strategy won't work as expected with ZSH options that don't preserve the history order such as `HIST_IGNORE_ALL_DUPS` or `HIST_EXPIRE_DUPS_FIRST`.
+- `history`: Chooses the most recent match from history.
+- `match_prev_cmd`: Like `history`, but chooses the most recent match whose preceding history item matches the most recently executed command ([more info](src/strategies/match_prev_cmd.zsh)). Note that this strategy won't work as expected with ZSH options that don't preserve the history order such as `HIST_IGNORE_ALL_DUPS` or `HIST_EXPIRE_DUPS_FIRST`.
