 ## Change Log
 
+### 18.3a2 (unreleased)
+
+* ignore empty bracket pairs while splitting. This avoids very weirdly
+  looking formattings (#34, #35)
+
+* remove a trailing comma if there is a single argument to a call
+
+* fixed missing space in numpy-style array indexing (#33)
+
+* fixed spurious space after star-based unary expressions (#31)
+
+
+### 18.3a1
+
+* added `--check`
+
+* only put trailing commas in function signatures and calls if it's
+  safe to do so. If the file is Python 3.6+ it's always safe, otherwise
+  only safe if there are no `*args` or `**kwargs` used in the signature
+  or call. (#8)
+
+* fixed invalid spacing of dots in relative imports (#6, #13)
+
+* fixed invalid splitting after comma on unpacked variables in for-loops
+  (#23)
+
+* fixed spurious space in parenthesized set expressions (#7)
+
+* fixed spurious space after opening parentheses and in default
+  arguments (#14, #17)
+
+* fixed spurious space after unary operators when the operand was
+  a complex expression (#15)
