### Numeric literals
-*Black* standardizes all numeric literals to use lowercase letters: `0xab`
-instead of `0XAB` and `1e10` instead of `1E10`. In Python 3.6+, *Black*
-adds underscores to long numeric literals to aid readability: `100000000`
-becomes `100_000_000`.

### Line breaks & binary operators
* adjacent string literals are now correctly split into multiple lines (#463)
-* code with `_` in numeric literals is recognized as Python 3.6+ (#461)
+* numeric literals are now formatted by *Black* (#452, #461, #464, #469):
-* numeric literals are now normalized to include `_` separators on Python 3.6+ code
- (#452)
+ * numeric literals are normalized to include `_` separators on Python 3.6+ code
+
+ * code with `_` in numeric literals is recognized as Python 3.6+
+
+ * most letters in numeric literals are lowercased (e.g., in `1e10` or `0xab`)
* cache is now populated when `--check` is successful for a file which speeds up
consecutive checks of properly formatted unmodified files (#448)
* note: the Vim plugin stopped registering ``,=`` as a default chord as it turned out
to be a bad idea (#415)
+* fixed formatting of lambda expressions with default arguments (#468)
