## Features
|
|
+
|
|
+- Add a new `--diff` option that can be used to only show lines surrounding
|
|
+ Git changes, i.e. added, removed or modified lines. The amount of additional
|
|
+ context can be controlled with `--diff-context=N`. See #23 and #940
|
|
+
|
|
## Bugfixes
|
|
## Other
|
|
## `bat` as a library
