+## [2.1.1] - 2020-09-08
 ### Changed
 - Polls will be hidden with status content if "Collapse posts with subjects" is enabled and the post is collapsed.
 
 ### Fixed
+- Network fetches don't pile up anymore but wait for previous ones to finish to reduce throttling.
 - Autocomplete won't stop at the second @, so it'll still work with "@lain@l" and not start over.
 - Fixed weird autocomplete behavior when you write ":custom_emoji: ?"
 
+
 ## [2.1.0] - 2020-08-28
 ### Added
