+## [Unreleased]

+-   When `InlineArray` cannot hold any values because of misalignment, report it as capacity 0
+    instead of panicking at runtime. (#22)

 ## [0.6.4] - 2021-02-17
 
 ### FIXED
 
--  `InlineArray` can be used in recursive types again.
+-   `InlineArray` can be used in recursive types again.
 
 ### CHANGED
 
--  `InlineArray::new()` now panics when it can't store elements with large alignment
-    (this was UB prior to 0.6.3). Alignments of `usize` and smaller are always supported.
-    Larger alignments are supported if the capacity-providing type has sufficient alignment.
