+### Empty lines
+
+*Black* will allow single empty lines left by the original editors,
+except when they're added within parenthesized expressions.  Since such
+expressions are always reformatted to fit minimal space, this whitespace
+is lost.
+
+It will also insert proper spacing before and after function definitions.
+It's one line before and after inner functions and two lines before and
+after module-level functions.  *Black* will put those empty lines also
+between the function definition and any standalone comments that
+immediately precede the given function.  If you want to comment on the
+entire function, use a docstring or put a leading comment in the function
+body.

 ### Editor integration

+Any tool that can pipe code through *Black* using its stdio mode (just
+[use `-` as the file name](http://www.tldp.org/LDP/abs/html/special-chars.html#DASHREF2)).
+The formatted code will be returned on stdout (unless `--check` was
+passed).  *Black* will still emit messages on stderr but that shouldn't
+affect your use case.
+
+There is currently no integration with any other text editors. Vim and
 Atom/Nuclide integration is planned by the author, others will require
 external contributions.

 ## Change Log
 
+### 18.3a3
+
+* don't remove single empty lines outside of bracketed expressions
+  (#19)
+
+* added ability to pipe formatting from stdin to stdin (#25)
+
+* restored ability to format code with legacy usage of `async` as
+  a name (#20, #42)
+
+* even better handling of numpy-style array indexing (#33, again)
+
+
+### 18.3a2
+
+* changed positioning of binary operators to occur at beginning of lines
+  instead of at the end, following [a recent change to PEP8](https://github.com/python/peps/commit/c59c4376ad233a62ca4b3a6060c81368bd21e85b)
+  (#21)
+
+* 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
+
+* if top level functions were separated by a comment, don't put four
+  empty lines after the upper function
+
+* fixed unstable formatting of newlines with imports
+
+* fixed unintentional folding of post scriptum standalone comments
+  into last statement if it was a simple statement (#18, #28)
+
+* 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
